The success of General Motors Corporation to develop battery materials
According to the report from British Green Car web site,Autel MaxiDAS DS708 researchers of General Motors technicians from MEDA Engineering and Technical Services and HRL Labs have made significant breakthrough on the battery technology hand in hand.
Famous energy materials academic Journal, “Journal of Power Sources” reported that the researchers of General Motor have developed silicon-tin composite as a new type of electrode material for lithium ion battery.
It is reported that silicon and stannum are the best materials as negative electrode, and they have superior theoretical specific capacities. However, in practice, during the process of charge and discharge, with the enter and exit of Lithium ion, the capacity will expand and shrink and then it is easy to break to led the mechanical degradation and cause the damage on electrode.
However now, the new c3 star material developed by GM, including an Nano-structure to isolate the materials. This material is used to implant the silicon nano particle seperated from Silicon tin alloys into the template, which can reduce the mechanical degradation and protect it from the appearance and expansion of microcrack.
