With the advancement of society and science and technology, the development and utilization of green energy and the continuous upgrading and updating of the electronics industry, the demand for energy storage technology is increasing, lithium-ion batteries are on the cusp of this new technological era, and have attracted the attention
of researchers at home and abroad in recent decades.
At present, the negative active materials used in commercial lithium-ion batteries are all graphite, and its actual specific capacity is about 360mAh/g, which greatly limits the energy density
of the overall battery.
Silicon materials, due to their theoretical specific capacity of 4200mAh/g, are more than 10 times that of graphite, which has attracted the input of many research groups around the world
.
Recently, the University of Waterloo in Canada successfully developed a new graphene silicon-based lithium-ion battery, this innovative technology will increase the specific energy density of the current commercial lithium-ion battery by 40%-60%, and extend the cycle life to more than 2000 times, which greatly promotes the development process of high-energy and long-life lithium-ion batteries, and promotes the accelerated growth
of the industrial chain in the field of related electronics and energy storage.
At present, this technology has completed the initial small test stage, and it is conservatively expected that this new graphene silicon-based lithium-ion battery will enter the market
next year.
