Li-ion battery |
| abstract |
PROBLEM TO BE SOLVED: To provide a high capacity retention rate after a plurality of cycles and to provide a long cell cycle life. A prelithiated silicon anode for a Li-ion cell containing 5 to 12 wt.% PVDF binder is provided. In a special example, the conductive additive can be added at less than 5 wt.%. The anode containing PVDF binder is prelithiated following Si anode fabrication prior to cell assembly. The combination of pre-lithiation and PVDF in a Si anode for a rechargeable Li-ion cell shows the unexpected result of extended cycle life. [Selection diagram] Fig. 3 |
