The problems of hydrogen evolution and sulfation in the negative electrode of lead-acid battery are the main factors limiting the performance of lead-acid battery.A lot of research focuses on the additives in the negative electrode.In this paper,the effect of acetylene black-coated lead and its oxide composite material on the performance of lead-acid battery was studied.The experimental results show that the addition of composite electrode can effectively restrain the hydrogen evolution problem,reduce the phenomenon of sulfation and prolong the life of the electrode.
