At the same time, the synthesis method and improvement scheme of the anode material can be applied to the next generation electric vehicle and the medium and large energy storage system.
Lithium Grid News: The Korea Institute of Science and Technology announced that it has used the lithium-rich manganese- nickel-cobalt-manganese oxide (LMR) material to produce a new anode material that can overcome the surface heating phenomenon. This technology can improve the performance of electric vehicle batteries . The research was published in the international academic journal Nano Letters.
LMR materials have higher energy density and safety than other anode materials, but the crystal structure will be unstable during charge and discharge. This phenomenon mainly occurs on the surface of anode material particles, which has limitations in commercial applications. The Korean technology keeps the surface of the LMR anode material stable, thereby forming a surface structure that rapidly transmits lithium ions, suppressing the heating phenomenon of the material, and the manufacturing process is simple and convenient.
The research results show that the new material maintains its original characteristics when it is subjected to high-speed charge and discharge more than 300 times in 2 minutes. This technology can shorten the charging time and increase the driving distance. At the same time, the synthesis method and improvement scheme of the anode material can be applied to the next generation electric vehicle and the medium and large energy storage system.
