High capacity battery electrode with improved binder, structure and performance

摘要

There is provided an anode material composition for a metal-ion battery comprising an active material coating, a current-conducting collector, and a conductive intermediate layer that bonds the active material coating to the current collector. The active material coating has a capacity loading of at least 2 mAh / cm ² and has a capacity of about 8 vol. % To about 160 vol. % Volume expansion and about 4 vol. During one or more subsequent charge-discharge cycles. % To about 50 vol. % / RTI by volume.
