A simplified profile imitating the micro-hybrid driving mode is performed on the lead acid batteries to evaluate the effect of the modified negative electrode design with half carbon paste as part of negative plate under high rate partial-state-of-charge operation (HRPSoC). In this work, we report that the half side carbon paste replacing half of the spongy lead negative paste in negative plate has significantly improved the cyclability of lead-acid batteries under high rate partial-state-of-charge operation. This is mainly attributed to the high specific surface area and conductivity of the carbon black. In addition it minimises the formation of irreversible lead sulfate at the negative plate. Thus, half carbon black on negative plate in lead acid battery eventually improves the performance characteristics of lead-acid cells under HRPSoC cycling
