Abstract: The traditional lead-acid batteries are mainly used for automobile and various internal combustion engine starting, wireless communication base stations and renewable energy storage; however, their negative plates are easily sulfated under partial-state-of-charge duty, then their charging capacity and cycle life are greatly reduced. Lead-carbon battery is a new type of lead-acid battery, in which a carbon material with high specific surface area and conductivity is added into a negative plate, and has excellent rate discharge performance and higher PSoC cycle life. Lead-carbon battery has a good application prospect in energy storage and hybrid electric vehicle, so these years the study of the mechanism of carbon materials in lead-carbon battery becomes a hot research topic. This paper reviewed the recent progresses in research on the mechanisms of carbon materials in lead-carbon batteries, mainly focused on the construction of conductive network, double-layer capacitance storage, improvement of pore structure, increase of electrochemical reaction dynamics and other aspects, as well as the research work of our group in Pb-C batteries.
