    To extend laptop battery life laptop users have been a concern, and now this question has had a better solution. Last week, Apple introduced the iBook’s battery can be six hours of continuous use.

    PC makers and chip companies to introduce power management technology, can save the battery for extended usage time. Texas Instruments Unitrode acquisition this week, the company that specializes in the manufacture parts with power management features vendors, Texas Instruments said that these products are analog semiconductors the fastest growing market. Intel also will launch a new technology known as Geyserville, power management will result in significant changes. Is estimated that the power problem will no longer be troubled by notebook computers.

    Geyserville the notebook when you plug in an electrical outlet, may have desktop-like efficiency, if only the battery, the machine will use a lower power consumption; general high power consumption for high-functional notebook PCs, able to lower the status of the efficiency of use for two hours.

    In general, the higher functions of notebook computers, power consumption increased. Intel mobile products department said Frank Spindler, vice president of marketing, Geyserville improve the efficiency of the notebook, but would not spend more power.

    Apple’s iBook also uses power management technology, when the computer is still time to enter the resting state, iBook’s new feature is available in this time of information storage, access to a rest state, this time using the iBook only a small amount of electricity. Some observers for the iBook to have six hours of electricity expressed doubts, but Apple spokesman said that six hours is a conservative estimate.

    Spindler said wait and see attitude, he considered that the use of calculating the number of hours the battery will depend on what was the use of a software and computer system configuration, so the calculation method will vary.

    China is the world’s second largest energy producer, is also the world’s second largest energy consumer. In the accelerated process of urbanization and industrialization, today’s energy problem has become a limiting rapid and healthy development of China is an important bottleneck. The increasing scarcity of traditional energy and the environment is getting worse, greatly promoted the development of new energy sources. Adjust the energy structure, developing a rich, clean new energy sources not only to achieve energy, economic and environmental development of the inevitable choice, but also reduce the reliance on international oil and ensure energy security. It is foreseeable that China will soon be large-scale development of new energy. Large-scale development of new energy sources and promote energy-saving environmental protection an urgent need planning large-capacity storage industry, which for the battery company’s future development has brought great opportunities and challenges. Who can occupy the development of new energy market opportunities, who will be able to compete in an invincible position to effectively resist the financial crisis.

    New energy vehicles into the weak link in the battery operation

    New energy saving and environmental protection advantages of car is very consistent with the sustainable development of China’s current uphold the concept and build a resource-intensive and environment-friendly society concept. The development of new energy vehicles in China to fulfill the responsibility of world powers together to combat climate change, an important path. As China’s policy of support for the increase, its technological level, China’s development of new energy automotive industry will be growing, there has emerged BYD, Chery and so have greater influence in the new energy vehicles on behalf of companies.

    To further promote the industrialization of new energy vehicles the process to address the high-tech product marketing, the size and cost of the initial contradiction between the promotion of a wider application of new energy vehicles, Science and Technology and Ministry of Finance jointly launched the “10 City, 1000″ application of electric vehicle demonstration project. Decided three years to develop 10 cities each year, each city in public transport, rent, public, municipal, postal areas such as introduction of new energy vehicles to carry out 1000 model run, and strive to make the country the size of the operation of new energy vehicles in 2012 accounted for automobile market share of 10%.

    Experts pointed out that under the current policy to stimulate the emergence of some enterprises in order to obtain state financial assistance funds, not from the accumulation of independent intellectual property rights to strengthen R & D to start, but wait to buy foreign key components of batteries and control system assembly, this so-called “systems integration” and its potential danger is that the core technology of electric vehicles in China are still are neither master, “assembling” the popularity of easily lead to a significant slowdown in the pace of independent innovation. The new energy vehicles three key components of batteries, motors, electric control, domestic enterprises is the weakest link in the battery, for battery performance, reliability, and product functions are still exploring, is far from the level of mass production. This means that the battery companies to win market, we must continuously improve the product cost in order to compete for new energy markets in the war come to the fore.

    The battery industry, relying on the global high-end industrial cluster event

    The huge market potential will require a high-quality event for the industry to promote the rapid growth of the power battery industry.

    Recently, Swedish scientists have used cellulose produced by algae, like paper-thin, lightweight, flexible battery can be used to track products from the origin to the shelf’s whereabouts, or used to track baggage through the airport security whereabouts. Related research published in the latest issue of “Nano Letters” on.

    Electrochemical reaction on the work of the battery, each cell contains two electrodes (cathode and anode), the two electrodes immersed in electrolyte. Now widely used in mobile phones and laptop computers in the lithium battery anode from the carbon composition of lithium cobalt oxide cathode by the constitution, dissolved organic lithium salt containing electrolyte. When the battery is when you pass on the power electronic North Korea embarked on the cathode, forcing positively charged lithium-ion away from the cathode into the anode, when the battery discharge, the current from the anode for lithium-ion to return to the cathode.

    Albert Te Milan Uppsala University in Sweden and his colleagues invented a result of the battery from the seaweed extract made from the cellulose (paper is extracted from trees or cotton, made from cellulose). Algae cellulose fiber is more slender, make a larger surface area of the battery so that it can store more charge.

    However, the fiber itself is not conductive, Milan because of the team using a common conductive polymer polypyrrole (polypyrrole) to surround fiber. Polypyrrole is usually amorphous black solid, insoluble does not melt at 200 ℃ when the decomposition can be conductive. The researchers report their submerged algae fibers, resulting in a mixture can be conductive. Then, they are in such compounds in the manufacture of a new battery poles, using filter paper soaked in salt water as electrolyte.

    The new cell consists of two cellulose electrodes and caught in the salt-impregnated filter paper composition, looks like a sandwich, two cellulose electrodes located in between two glass slides. Poles attached to the platinum with the formation of conductive contact with the outside world. In the polypyrrole chemical changes occurred in storage and release of power, in which the molecules exist in two forms, that is the term called “oxidation state” and “restore state”, when these two states of the molecules to form loops, that is to generate electricity. The battery can be charged within a few seconds, but after 100 charge-discharge performance does not appear large losses.

    Dr. Milan are due to find a business for this scientific and technological achievements “mother.” At present, the efficiency of algal cells is only one-third of lithium-ion battery, which although not a substitute for lithium batteries, but there are also a unique display their abilities, can be used with a small radio devices, luggage tags, using the signal to Luggage regulators to track the location of baggage; also be used for “smart” packaging materials, such as with electronic display box. In addition, Dr. Milan battery can also be due to the recent successful development of the transistor components of paper-based charge.

    Only in the UK, every year more than 100,000 tons of medium-density fibreboard (MDF) has been discarded by the furniture industry, however, abandoned fibreboard now have a new use. According to “New Scientist” magazine recently reported that the waste fibreboard in the case of non-combustion can be converted into electrical energy. Micro-energy generation technologies that can help reduce the plant to obtain energy from external resources consumption, but also in the generation process can produce more storage emissions.
    With the building trade in the past 30 years the rapid development of tens of thousands of medium-density fiberboard into the market. This cheap fibreboard, flexible, and will not be the same as the timber was broken and has become very popular furniture manufacturing industry, one of the materials.
    United Kingdom University of St Andrews and his team of John Owen said that the medium density fiberboard in the minimum can be modified for a direct carbon fuel cell (DCFC) to provide power. Direct carbon fuel cell is a highly efficient, clean fuel cell technology, its principle is that carbon and oxygen and re-gasification Needless to directly produce electricity through the electrochemical reaction, the efficiency of up to 80% fuel utilization rate of about 100% .
    As a result of a direct carbon fuel cell will not be wasted heat, the efficiency of internal combustion engine capacity of up to 2 times, has been developed to molten carbonate, solid oxide and molten hydroxide as the electrolyte of a wide range of direct carbon fuel cell. Although the use of a direct carbon fuel cell will emit carbon dioxide, but gas is a clean way on the release, unlike the burning of carbon fuel emissions produced by the same mixture of nitrogen and other wastes, which greatly reduces carbon capture the difficulty of avoiding the emission of atmospheric pollution, pollution control and energy conservation on the importance of reducing emissions.
    Owen and his research team first of all, the high temperature at 500 ℃ under nitrogen environment broken MDF carried out so as to remove water vapor and other volatile gases. Owen said that this process will enable low-cost medium-density fiberboard is a step up, portable, easy to be sent to the space required. Subsequently, the researchers treated fiberboard made from dried powder, mixed with lithium and potassium carbonate as the electrolyte fuel cell. At 500 ℃ in temperature to between 800 ℃, the mixture will lead to medium-density fiberboard with carbon and oxygen into the cells within the combination of electron ionization and produces carbon dioxide, and to generate the required current.
    The battery can be made in current density of 200 milliamperes per square centimeter provide 100 milliwatts per square centimeter of power, which means that a side length of 10 cm square current of the battery in the case of 20 amps produce 2 volts. This and other types of direct carbon fuel cell is similar, can be applied to large-scale power plants.
    Technical University of Delft, the Netherlands, although the Kass Moss expressed support for the study, in the future, direct carbon fuel cell may be a major role in the chemical decomposition of hydrogen gas, and other types of fuel cells to provide energy after the consumption of the remaining carbon. But the use of medium density fiberboard and other small-scale waste of energy generated in the market can still find room for development.
    At the same time,Kass Moss also would like to see more information on the data medium density fiberboard. In his view, the research team only shows that the number great enough fiber, the researchers still need to further quantify the real data to the realization of this study provide support.
    China’s Harbin Engineering University Materials Science and Chemical Engineering College Professor Cao Dianxue view, looking for direct carbon fuel cell powered by the new raw materials that fuel cell technology is an important aspect of the success of his team of Owen for the non-traditional energy sources also said that innovation the praise of Italy.
