Influence of different carbon materials on performance of lead carbon negative electrode

Different proportions of granulated carbon black and activated carbon added in the negative paste of lead acid batteries. Partial state of charge state (PSoC) cycle times are tested respectively through constant-current charge-discharge. Carbon material and negative active materials (NAM) were characterized by SEM and XRD. The results show that both granulated carbon black and activated carbon can incorporate in lead to form the structure of lead carbon which may significantly improve the PSoC cycle performance.
