Battery News

Beginning July 1 implementation of “new energy companies as automobile manufacturing and rules of access management products,” which states that “the use of lead in car battery acid passenger hybrid clean cars of electric and pure electric vehicles and the use of nickel-metal hydride Powered hybrid is classified among the products mature. “Before the loudest voices were included in the stage of vehicle development lithium battery, not a wide-scale promotion of the column.
Performed in Frankfurt, Germany Frankfurt Auto Show, to Daimler - Benz, Volkswagen, Toyota car dealer, represented expressed their optimism about the development of lithium batteries, and a series of hybrid vehicles powered by lithium batteries to reduce emissions carbon vehicles. Such as the Toyota van in carbon emissions of a mere 60 g / km (average annual emissions of ordinary cars 5.000 kilograms).

Then, the outlook for lithium batteries at the end?

New car electrical components is the most important driving force of batteries, electric motors and the system of energy conversion control. The new energy vehicles demanding on the battery, you must have a higher specific energy, high specific power, fast charge and discharge performance deep, and requires the lowest possible cost, life also long as possible. Therefore, the battery pack is a technical threshold of the highest, is also the most concentrated benefits.

Lithium batteries in the rapid growth phase

Car manufacturers usually choose to use lithium batteries as a power driving new energy vehicles, the value of industrial production has enormous potential.
The traditional lead-acid batteries, nickel-cadmium batteries and nickel-hydride technology of metals of the battery itself is relatively mature, but they are used in automotive batteries as power, there are still major problems . Li-ion battery has a small, lightweight, high voltage (which is nickel-cadmium batteries, nickel-hydrogen batteries 3 times) that the energy of large (up to 165WH / kg, nickel-hydrogen batteries 3 times), cyclical long-term self - a low rate, no memory effect, no pollution, safety, and good, a great choice for car manufacturers as a new power battery energy lithium car battery.

China Lithium-ion battery industry started late in Japan, but the very rapid development in recent years, particularly in the food-lithium battery research and development ion have invested considerable financial and material resources. Lithium Chinese automotive-ion battery R & D project was the 863 “national” key project, much of the equipment to perform the localization and the introduction of multi-national materials has been self-built production lines and support, the plants have more than one, were the formation of large-scale production, intense market competition.

Automotive Li-ion battery industry because of enormous value inherent potential of electric vehicles, suppliers of battery materials upstream and downstream of the automakers have begun to enter the automotive battery. Li-ion battery is behind the price of hot cars on the plug-in hybrids (also known as plug-in hybrid electric vehicles) and pure electric vehicles, the market prospects of recognition and R & D capabilities of their current concerns.

As the United States Ford, Toyota, Mitsubishi, Nissan, Hyundai, France, Courreges, Ventury and other companies have launched their own lithium Motor Vehicle Program. While the domestic automaker BYD, Geely, Chery, Lifan, ZTE and other car firms also have their own hybrid and pure electric powered by lithium battery.
Therefore, the development cycle, the current market for automotive lithium battery is out of the start-up stage and began undergoing rapid growth.

Insufficient to solve the load and over-discharge phenomena

The level of security and the vehicle battery power management system is the bottleneck of the development of lithium batteries.
Currently, Chinese companies in BYD downstream Wanxiang Group, Shenzhen BAK Battery, Tianjin Lishen Battery and U.S. joint ventures Myers. Currently the only control of the vehicle battery pack lithium iron phosphate production technology of large scale, BYD Company, has officially launched its self-developed lithium-E6 Battery Powered F3DM pure electric vehicles and hybrids.

Currently, however, hinder the development of lithium-bottlenecks are ion battery: safety performance and vehicle power management system battery.
Automakers based on safety, oriented concept, the battery safety has presented a very high demand. As the supply voltage of 12V vehicle battery or 24V single power lithium-voltage ion battery is 3.7 V, it must be used by multiple cells in series, but difficult to achieve because of the burden and discharge the battery completely homogeneous, resulting in the battery discharge appears imbalance that occurs under load and over-discharge phenomenon, the situation will lead to a sharp deterioration in battery performance, eventually leading to all group of cells does not work, or even scrapped significantly affect battery life and reliability.
Therefore, lithium-ion battery power for good purposes, materials needed, batteries, systems management, taking into account the mechanical and other aspects. Therefore, firms in upstream and downstream should work together on drums as a core material, the management system requests formation of an industry group, would be conducive to technological progress and system costs.

Average price of materials, manufacturers continue to realize the localization and improved techniques
Barriers Lithium battery cathode materials with high entry, the minimum capacity, the anode materials for the industrialization of China has been achieved, the technology and the electrolyte membrane is still dependent on imports.

The lithium batteries can be divided into electrode (positive / negative) materials, separator and electrolyte. Material for Li-ion battery cathode is at the heart of the current cobalt oxide lithium, lithium manganese, lithium and nickel-cobalt-manganese-based lithium iron phosphate. Ze Yi graphite anode material, solid particles of carbon-based, amid the positive and negative electrodes while the electrolyte and battery separator.

As barriers to entry, material of the lithium battery cathode is the smallest capacity, which is the chain industry as a whole, the most promising aspect. Cathode materials currently in production companies are: China Baoan, CITIC Anhée Shanshangufen, BYD.

Compared with the cathode materials, anode materials, graphite, particles of solid carbon, which represents the proportion of low cost batteries, lithium, and the servant who has been achieved industrialization. Currently engaged in business in lithium battery cathode material production are the first three of the Chinese national security, capacity Shanshangufen shahi long. It is noteworthy that the negative electrode materials present in any position to meet market demand mainly domestic, but with the growing popularity of vehicles, new energy future, this application will be a massive shortfall.

Manufacturers of household batteries supporting electrolyte has been performed mainly at national level. Lithium hexafluorophosphate electrolyte main raw material, which represents about 50% of the cost of the electrolyte, its production cost is 10 yuan / ton, the price of 40 yuan / ton, gross margin reached 75%, but the market has been widely Electric Kanto Chemical Industry, SUTERAKEMI-FA, Morita chemistry, several Japanese companies a monopoly.

Divide the Department of Li-ion materials technology, barriers to higher value-added material, the gross margin is generally 70% or more, representing the cost of lithium batteries 20 ~ 30%. It is reported that the car needed to 1000-2000 m2 membrane. Currently, a serious shortage of market supply diaphragm, the most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Domestic firms can produce only stars membrane technology source, Jinhui High-Tech two technologies are relatively mature.

Upstream to find the resources and technical barriers to a breakthrough in
Lithium iron phosphate power battery cathode materials, investment opportunities the most promising, but reserves are limited, the process technology for the simultaneous separation of lithium carbonate is only a few hands of foreign companies .

Power Lithium iron phosphate battery cathode materials, investment opportunities the most promising, the key raw materials, lithium iron phosphate is lithium carbonate, lithium carbonate from mineral resources in nature reserves are limited, with strong regional and scarcity of resources belonging to rare. Thus, in the chain of new energy automotive industry, the strategic resources of lithium carbonate become particularly important.

Currently, the Global Fund, lithium carbonate industry, the status quo, the threshold of significant resources, capacity is highly concentrated. At the end of 2007, major international manufacturers have SQM in Chile, the United States, FMC and Germany Chemta the total annual capacity of 78,000 tonnes, representing 80% of global market share. With the company producing the large scale must have reserves of lithium resources are more abundant in salt lake resources, mineral rights, making the resources of industry with higher barriers to entry, secondly, the vast majority of the planet’s resources are at high magnesium salt type lithium lowest of the high-and low magnesium lithium separation of brine purification of lithium carbonate in the process technology is very difficult, but these techniques only a small number of foreign companies rests in their hands, so that the area is very technical obstacles.

The current national production of lithium carbonate businesses mainly in Tibet, mining, CITIC Guoan, Western Mining Group, Qinghai Salt Lake Group, the four companies, while the extraction of Tibet and CITIC Guoan has accounted for the vast majority, the two companies in 2008, lithium carbonate Total production over 4000 tons.

It is estimated that each new type of electric vehicle needs about 0.08 tons of lithium carbonate, lithium batteries, once the engine of large scale application of new energy vehicles in 2012 that cars energy news on demand of lithium carbonate will reach 5 million tons. While domestic prices of industrial lithium carbonate years to 4.5 yuan / ton level of lithium carbonate price of 7 yuan / ton, the high purity lithium carbonate price is as high as 10 yuan / ton involved in local projects of the new as it is used Salt Lake brine extraction of lithium carbonate production costs 10,000 ~ 1.5 yuan / ton. Therefore, the market generally felt that the profitability of products of lithium carbonate is very high.

Afternoon of yesterday, the allocation of elite business meeting will be on site smoke “,” contest organizers from around the world the book program, 688 copies of a selection of six projects are competitive high international level of high technology products.

Zhang Xia-Chang to play alone. He first took a piece of paper, and he soon came to a shirt pocket, less than one cubic centimeter of the black object, “This is my invention of the stack of paper,” stack of paper with white contrast, as the thin, less than half a millimeter thick at the scene was immediately attracted.

Shortly after, Zhang Xia-Chang withdrew a map of the lithium battery and replace the battery from the invention of paper, “Happy Birthday to You!” Immediately echoed at the scene.

The provisions of this competition, entrepreneurship Elite Award winning project must be completed within 6 months after registration corporation, the capital of at least three million yuan, the equivalent of 300 million yuan foreign currency. Company to complete the registration and the capital of any place, within 1 month after, Ningbo National Hi-Tech Zone to offer 100 yuan as “the business elite Award.”

Thin flexible paper battery in 2007 by the U.S. Time Magazine as “the best innovations of 2006, one of eight”, the same year, Zhang Xia-Chang also won the Phoenix Satellite TV and other media on behalf from “2006 Award of Chinese influence in the world. ”

What piles of paper? “This is the stack of paper, he uses one side galvanized on one side of the thin layer of paper coated with manganese dioxide as a conductor, each thickness is less than 0.5 mm, and Soft paper. These two spots are the positive and negative poles. “Xia-Shang your pocket and thick card-sized Business Golf-sized” pieces of paper, said: “For example, we Now look at a newspaper that has only text and static images, they are installed on paper in the stacks of newspapers, you’ll be able to run a newspaper
  
In the “2006 China in the World Award” ceremony, someone said enthusiastically: “With the piles of paper, after the laptop can be very practical!” Later, also said: “The document will be the advent of battery to solve the energy crisis of human improvement! “Zhang Xia-Chang true that this is a media and public opinion in the piles of paper that came when the common misreading.” Compared with ordinary button battery, the battery voltage of 1.5 V, the cost of very low (a few minutes to a few cents each), materials, environmental protection, and has advantages such as garbage, the size and shape of flexible, easy-to-application integration. can be used as cosmetics, smart cards, musical greeting cards, the membrane epidermal Human Drug permeable permeable products skin care, paper, LED, electronic paper, sensors and identification tags Radio frequency (commonly known as RFID) products such as Power Supply to avoid the traditional batteries to produce metals, lithium and alkaline compounds the problem of leakage.
  
This soft, low-cost battery will be a great comfort. Use it to produce the electronic tags can replace the labels with traditional bar code, smart. Zhang Xia-Chang, for example, imagine that in the supermarket, the customer can simply select dozens of bags of different kinds of food and other items on the carts pushed to the fund, where next to each item on the packaging of electronic tags will be placed on the reading signal, the client may leave after the payment, without staff, and the fight against the theft rate was 100%.

The greatest advantage of laptops is mobility, provide the basis for all this is the battery. In the energy-saving technology and battery technology being a time when there is no breakthrough to fully optimize the battery and master the use of a number of related techniques would be helpful. However, laptop battery life is longer, often dissatisfied with the charge, and even shows the battery is damaged, it must pay particular attention to the use of certain skills dell Inspiron 6400 battery,dell Inspiron 640m battery.

First, choose the best time to repair
Laptop battery there is an inevitable part of aging, almost all of the repair methods are trial “deep charge deep-release” principle, in order to ease the laptop battery memory effect. Undeniably, however, the depth of the charge and discharge operation will not be good for the laptop battery itself, is a must not to do this method. If the battery life to merely reduce the dozens of minutes, then care should be taken to this method of operation. In addition, the pool of laptop battery manufacturers has been optimized, there is no self-depth again to upgrade the battery charge and discharge capacity argument. However, exactly when you need the depth of charging and discharging is very difficult to master, after all, every time the electricity consumed are not the same, it is suggested we BatteryMon with this professional software.

BatteryMon is a specifically for the small laptop battery monitoring software, especially for those who are not built-in power management chips and software, machine, it will undoubtedly help a lot of great help. BatteryMon most salient feature is able to discharge curve, and the installation will run automatically. A good performance of the battery will have a very regular discharge curve, as shown, basically a grid for every drop of time are probably the same. If found to have a very unusual beating, then it is necessary for cell “deep charge deep-release” repair dell Inspiron 700m battery,dell Inspiron 710m battery.
Second, “deep charge deep-release” of the basic method
Batteries correction is an effective way to deal with aging batteries, in general, the various brands of notebooks will have a dedicated battery calibration software. For example, IBM’s ThinkPad series of discharge dedicated software, recommended for all to use IBM notebook users. But the program need to be repeated three times to get the best results. Download the software and the implementation of discharge, the system will be prompted to create installation disks. Use the installation disk boot PCDOS, unplug the AC power supply prompted, discharge the software will automatically discharge control. When everything after the notebook will automatically shut down, and then we can be connected to AC power for charging, time control in the 9 ~ 12 hours, repeated for 2 or 3 times can be.

For the laptop battery activation, our key software to find a suitable discharge. Unfortunately, if your laptop is not specialized discharge software, you can be shut down in the BIOS and Windows power management features, and then do not run any programs where the battery runs out, and then in the boot state to 80% of charge , repeated a few times also equivalent to manually “deep charge deep release.” In fact, this approach aims to make continuous small current laptop battery discharge, which discharge status in our daily use is unlikely to be achieved, the effect of the discharge and those dedicated basically the same software dell Inspiron 8500 battery,dell Inspiron 8600 battery,dell Inspiron 9200 battery.

An external laptop battery could be the perfect solution for those who must use the very mobile conveniences of the laptop, but need the power availability of the larger desktop models. With technology and business on the go growing by leaps and bounds, business men and women (or anyone who has come to depend upon the extreme conveniences of these travel computers) are discovering the challenges that come with being dependent upon mobile networks. The reality of having technology, business, personal information, clients, and files at the one’s fingertips at all times has developed an new style of commercial industry. More businesses than ever before have employees and subcontractors that are no longer in office, but on the road, working from home, or taking care of business while flying to new clients and countries around the world.

And so, the business world has changed. But, the challenges of having access to business systems twenty-four-seven has emerged and company tasks cannot be accomplished when that gold old constant computer companion has died for lack of battery power. But, never fear, there has been a response to the need for mobile light-weight, additional power and the result is the external notebook computer battery.

Work and play today equate to work and play on the go. This is a reality of the culture that we live in. As companies continue to expand to world wide enterprises and productions increase to meet the needs of many societies, combining office tasks and travel are necessary. The demands upon technology are high, however. Not only do we need technology to be lighter and easier to manage on an airplane or in the back of a taxi cab, but we need it to accomplish more, know more, file more, and offer more running time. Initially, manufacturers attempted to make better batteries that would last longer, and some have been successful. But, now the external laptop battery is the device that is providing the best solution. Anyone who uses a laptop daily will want to investigate the different models that are available on the market and discover that the amazing external notebook computer battery can add valuable work time by added uninterrupted power.

The new models of external power offer the same mobility that the latest laptop computers are offering. Some of the external laptop battery options available are less than one-half inch thick and weigh less than two pounds. These models will fit into almost any computer case and become part of the necessary accessories that users will need at all times. External notebook computer battery packs can be charged apart from the computer, giving the user the ability to charge in another location. Most of the models on the market will adapt to several of the major manufacturer’s models, as well. Different batteries advertise different power times, but most have a run time of five hours with some boasting an eight hour continuous run time. Run time will also depend upon what types of programs are being used on the computer. Programs that require more power, such as games, can drain a battery of power. And with the length of some international flights, additional run time offered from an external source could come in very handy.

Some computer manufactures offer external laptop battery packs as an option with certain models. There are also several manufacturers that make external batteries adaptable to most computers. There are some of these power sources that also come with car adapters, so batteries can be charged without an electrical outlet source. These power sources can usually be used with DVD players, cell phones, electronic games, and cell phones. Those wanting to find a way to extend the running time of their computers can begin price comparison shopping online where many of these power sources are advertised.

When looking for the right power source to extend computer running time, it may be wise to talk to others who have experience in electronics and accessories. As with any new device that enters the market, there are usually a few bugs to work out and the prices come down as the instrument is produced by more manufactures. The Bible, God’s Word of wisdom to man, explains that getting the counsel of experts will always lead to making wise decisions and choices. Take time and to not only price-compare when shopping for external notebook computer battery packs, but speak with salesmen and the manufacturer of the laptop, as well.

Consumers will want to also beware of cheaper batteries that are available through the Internet. Poor quality external laptop battery sources do exist in this competitive market. When a battery is as much as thirty percent cheaper than comparable models on the market, consumer may want to assume that the piece has been assembled with cells that do not meet UL standards. Check for UL standards before buying any battery power source.

Float charging is most commonly used for backup and emergency power applications where the discharge of the battery is infrequent. During float charging the charger, battery, and load are connected in parallel. The charger operates off the normal power supply which provides current to the load during operation. In the event of normal power supply failure, the battery provides backup power until the normal power supply is restored. Since most equipment requires alternating current, a rectifier circuit is usually added between the battery and the load. Float chargers are typically constant-voltage chargers that operate at a low voltage. Operating the charger at a low voltage, usually less than about 2.4 V per cell, keeps the charging current low and thus minimizes the damaging effects of high-current overcharging.

For valve-regulated batteries, an important consideration when float charging is the possible occurrence of a phenomena called “thermal runaway”. The best way of preventing thermal runaway is through the use of a temperature-compensated battery charger. A temperature-compensated charger adjusts the float voltage based upon battery temperature. Temperature-compensated chargers will increase the reliability and prolong the life of the battery/charger system. They are especially useful for batteries located in areas where temperatures may be significantly above ambient conditions.
