Effect of roll ratio between double roll on the characteristics of negative electrode
Effects of two different roll ratios between double roll on the characteristics of negative electrode and bat-tery performance were investigated.The results showed that the rebound rate of electrode rolling thickness,peel strength,baking thickness,electrolyte infiltration thickness,full charge thickness,first efficiency of the battery and battery thickness were slightly smaller than that of the single roll process,in which the larger the proportion of the first roll was,the smaller the proportion of the second roll was,and the result also gradually decreased.The amount of residual battery fluid is reversed.There are many factors affecting the internal resistance of the battery,they are less related to the rolling process.
