摘要
Abstract
The slurry,mixed by Cobalt Acid Lithium and conductive graphite,binder (PVDF) in the proportion 90％ ∶3％ ∶ 7％ (mass fraction),and type 563048P Soft-package Lithium-ion Batteries was manufactured through winding with the capacity of 850 mAh.The effect of the material particles for positive plate surface was discussed.At the same time,the effects of granules for battery production process and electrochemical performance were studied.The results show that when using smaller mesh and don't use recycle material in the process of being mixed slurry,the short circuit ratio of roll core falls by 90％,the fraction defective of voltage decay of K value reduces 3/4,and the capability of keeping electricity and cycle performance are improved,and the capacity remains above 94％ after 300 cycles.关键词
