    Researchers at the University of Weston
    in Canada used the University of Saskatchewan's Canadian Light Source (CLS) to conduct battery technology research and found that applying carbon to lithium-ion rechargeable battery components extends its life to 50 percent.
    that thin carbon-based coatings extend battery life
    -
    solves the problem many consumers face, namely, that rechargeable batteries become less charged over time.
    Li is a Mitacs Project Fellow at The University of Weston's School of Engineering and a leading researcher in battery technology

    . "A thin carbon-based coating has been applied to the aluminum foil that conducts current in rechargeable batteries, and although this is a small change, we found that the carbon-based coating protects the foil from electrolyte corrosion in high-pressure and high-energy environments, resulting in a 50% higher battery capacity than a battery without a carbon coating," she said. Dr
    Lee is a member of the Weston Clean Energy Advanced Materials Group, which is run by Andy Sun. Researchers at Weston University worked with 3M Canada, which provides carbon coatings, and CLS, which provides the synchron accelerator light energy needed to test coatings, to study battery technology.
    3M Canada's ultra-thin coatingaluminum foil is typically used as an electrode setr for rechargeable lithium-ion batteries. This aluminum foil is highly conductive, light in quality and low in cost, but the new generation of batteries presents new challenges for the collection, which requires greater chemical stability to prevent corrosion of cathode electrolytes for longer battery life.
    team tested an ultra-thin coating of graphene produced by 3M Canada, although they had not yet found a new material for cathode.
    with the
    development of battery technology
    , Dr. Li regards electric vehicles as the main application area of battery technology, which is a green energy project in general.
    : "We are very concerned about the use of battery technology to promote the formation of a new clean energy environment. For humans, oil resources are not a long-term option, and when converting to green energy, we need clean secondary energy storage facilities. An important
    for a green futurebecause of the conductivity, flexibility and accessability of thin carbon coatings, this material could be an important means of developing battery technology for a greener future. For years, the Andy Sun team has been using the synchron accelerator light energy provided by CLS to develop more advanced batteries.
    Andy Sun said, "Without synchron accelerator light energy, it's hard to understand the chemical and electrochemical reactions of batteries." But synchron accelerator technology can tell us what kind of reaction will happen and provide very important guidance for the design of future battery materials. In
    X-ray

    team also used very bright X-rays from CLS to observe chemical changes on the surface of precision batteries in operation. The results show that the coating can play an effective role in both high-pressure and high-energy environments, which is very important for applications such as electric vehicles.
