    New CO tolerant catalysts used in the new PEM fuel cell

    battery news 3 Comments

    Research team at Cornell University July 26 announced that it has developed a new stability and resistance to platinum CO / anode of titanium oxide tungsten (Pt/Ti0.7W0.3O2) electro-catalyst can be applied to PEM fuel cells. The results were published in the Journal of the American Chemical Society.

    In front of the fuel cell cars and phones used in the challenges of electronic commerce is to develop low cost, sustainable and effective catalyst for hydrogen oxidation. Platinum is currently used as a catalyst but it is vulnerable to low levels of CO (10ppm) poisoning, which lead to significantly reduced performance. Other studies show that platinum oxide, in particular, tungsten, showing a high tolerance to CO. However, the disadvantage of tungsten is low electronic conductivity.

    To resolve this problem, Hector Abruña Cornell team led by Dr pass titanium dioxide (TiO2), titanium dioxide is used in fuel battery as a catalyst. electronic conductivity of titanium dioxide is much less than the conventional carbon support. But the team that can enable them to improve the cation substitution.

    Cornell team synthesized platinum nanoparticles on the conductivity of the burden of Ti0.7W0.3O2 above.

    The first test showed that Pt/Ti0.7W0.3O2 Pt / C and PtRu / C catalyst is more stable. After 500 cycle time, the catalyst for a new integrated Coulomb loss was only 0.5% while commercial E-TEK PtRu / C catalyst is higher than 30%. And Pt / C and PtRu / C catalysts, new materials also show, there is always high H2 oxidation activity and higher CO tolerance, the work of the U.S. Department of Energy and the Centre on energy support.

    Carbon nanotubes make li-ion battery energy storage and life double, can be listed soon

    battery news No Comments

    Massachusetts Institute of Technology researchers has found that the use of materials for lithium battery cathode of carbon nanotubes to obtain the charge efficiency and charge storage capacity than most lithium batteries of high-end quality. The battery electrode using the technique of cascade through the positive without additives, high density and function of the composition of carbon nanotube multi-walled titanium oxide lithium is extremely negative battery electrode thickness only a few microns.
      
    Energy production of lithium per unit weight than conventional electrolytic capacitors to 5 times more power than conventional lithium ion batteries 10 times during the life cycle of thousands of performances over a lithium battery with nanotubes carbon battery life.

    The new lithium batteries for smart phones and other portable electronic products the user is probably good news, but the current of the battery with carbon nanotubes is still in the labs. Controlling the spread of the main reasons for the new battery is made with carbon nanotubes in the battery electrode substrate before the batteries need to dissolve in two different soaking liquid, and this process is extremely long. Currently, the most viable solution proposed is sprayed through the substrate material irreplaceable carbon nanotubes to replace the dissolved solution in the process of the battery of soaking time.

    Although this electrode can be used in small portable devices at first, but further study will be used for large equipment, such as cars. I believe that carbon nanotubes can be listed near the battery, then use the smartphone users will no longer be sufficient for the problems of cell phone battery and sentence.

    The researchers made the new solar cell, can do the clothes power generation

    battery news No Comments

    University of Southern California researchers have successfully developed a very flexible transparent film of carbon atoms in the material, and used to create organic photovoltaic cells. The researchers reported that carbon materials are widely used, such as curtains and is expected to produce solar energy on their own clothes.

    Researchers in a new academic journal, “Nano-American Chemical Society” the report said the new material, called graphene, a layer of conductive carbon atoms excellent, only a few atoms thick and the use of graphene can be organic photovoltaic cells convert light into electrical energy. Now, researchers have been able to make graphene a variety of sizes, the largest is 150 square centimeters.

    However, this efficiency graphene organic photoelectric conversion of solar cells is lower than the silicon solar cells. Per square meter solar silicon solar battery can light 1000 watts in 14 watts of power, while the same area of graphene organic photovoltaic cells can be translated to 1.4 watts of power. However, graphene low cost organic photovoltaic cells, and good flexibility, the demand outlook so.

    In Ake Lewis participated in the study, for example, the new material can be converted into household curtains and even clothes made of will power. Right now, people can wear jogging clothes in the sun for example, during the loading of the mobile phone or audio-visual equipment.

    Applied Materials stop selling turnkey thin-film solar

    battery news No Comments

    Applied Materials said Wednesday to stop new sales of its “turnkey” SunFab thin-film solar manufacturing line and concentrate on silicon solar and LED lighting.

    The restructuring of its Energy and Environmental Solutions business will lead to the elimination of 400 to 500 positions and a third-quarter charge between $375 million and $425 million.

    Applied Materials had been selling SunFab, an integrated line of equipment to manufacture amorphous silicon thin-film solar panels, but the business has been losing money for months.

    In a statement, Applied Materials CEO Mike Splinter said Applied Materials will seek growth by selling equipment for making crystalline silicon solar panels and LED lighting.

    The company will stop sales of SunFab but will continue to sell individual pieces of equipment for thin-film manufacturing. Another technology Applied plans to pursue is electrochromatic glass, also called “smart glass,” which can change tint or color automatically.

    Many companies have developed new thin-film solar battery technologies in the past decade but most companies have had trouble bringing thin-film to market at large scale because of competition from silicon solar panel providers and incumbent thin-film providers, such as First Solar.

    Nissan investigate the best warranty of Leaf battery

    battery news 2 Comments

    General Motors announced the Chevrolet Volt will get an extended 8-year or 100,000-mile warranty on its battery. Now Nissan has sent electronic surveys asking participants about how long the Leaf’s battery warranty should be.

    The survey was sent to consumers who have reserved a Leaf with a $99 reservation fee. According to Nissan, that is more than 9,500 people.

    Nissan is apparently asking participants to report on the lowest level of warranty coverage they’d accept before not considering the Leaf.:

    The year and mileage on the survey range from 10 years or 200,000 miles to a basic three-year, 36,000-mile powertrain warranty that we see on most cars today.

    Another question asks respondents if five years or 60,000 miles is a good enough to seriously consider a Leaf. Nissan’s survey also asks respondents if they would cancel their reservation if the warranty ended up being five years or 60,000 miles. That sort of makes us think that this is the warranty Nissan was shooting for before GM’s announcement. The survey goes on to ask whether or not an eight-year, 100,000-mile warranty would change the buyer’s opinion of the Nissan brand.
