This technology is the use of polysiloxane technology to develop high-energy silicon negative electrode materials. After years of research, it has successfully discovered and developed a series of methods that can greatly improve the performance of silicon materials, including the suppression of volume expansion problems during charge and discharge The occurrence of irreversible phenomena in the cycle life will further increase the amount and future of silicon materials used in current lithium-ion batteries.Silicon has a very high energy density, so it has always been a material that the industry is eager to commercialize. However, the reaction of silicon and lithium ions causes the volume of the alloy to expand rapidly, which leads to the cracking of the material and the resulting cracked surface easily reacts with the electrolyte. The above problems occur repeatedly, which ultimately leads to poor cycle life of the material and limited application. This technology can complete the improvement of the above problems and complete the development of ultra-high energy density lithium-ion batteries (> 1200 Wh / l).This technology will be used in all lithium-ion battery-related products, including 3C electronics, electric vehicles, electronic components that require high power, and energy storage. Especially for the design of the next generation of ultra-high energy density (> 500Wh / kg;> 1200Wh / l) lithium-ion battery, this battery will use high content silicon material as the negative electrode so that graphite/carbon and other materials commonly used in the past will be used Elimination will further reduce the global problem of carbon demand and emissions.
