摘要：
A silicon anode comprising a hybrid binder at a blending ratio of 10-90 wt. % for use in a Li-ion battery is provided. The combination of a hybrid binder in the Si anode for use in a rechargeable Li-ion cell shows the unexpected result of extending the cycle life and a balancing effect between adhesion strength and first cycle efficiency.
