Effect of the pitch-based carbon anode on the capacity loss of lithium-ion secondary battery

摘要

The total capacity loss of lithium-ion secondary cell is reduced by engineering the pitch-based carbon anode through one or more of the following methods;attaining a high degree of graphitization,minimizing the surface oxygen concentration,attaining a large crystal size L_c,degassing,and use of PVDF inplace of teflon as the binder.
