A New Type of Activated Acetylene Black and PbSO4 Hybrid Material as A High-performance Lead-carbon Batteries Anode Additive

Abstract

Acetylene black (AB) is used extensively as a primary carbon material additive for traditional lead-acid batteries negative electrodes. Here we prepared an activated acetylene black@PbSO4 hybrid composite (PPA) via a simple microwave method to replace the original AB material as a more suitable anode carbon material additive for lead-carbon batteries. In battery performance tests, addition of acetylene black@PbSO4 composite can greatly improve the electrochemical activity of the negative plate. The high-rate partial charge state (HRPSoC) life of the lead-carbon battery with 5 wt% acetylene black@PbSO4 hybrid composite reaches nearly 26000 times, which is 33.1 times that of the blank battery (785). The composite in the negative electrode can also effectively suppress the hydrogen evolution effect caused by the addition of AB in the negative electrode plate.
