Abstract: This paper reviews the research and development of electrochemical synthesis of succinic acid at home and abroad. The cathode materials，anode materials，electrolytic cells and membrane materials are introduced and their characteristics are summarized. Lead and its alloy are still adopted as cathode by industrial manufacture because of their favorable performance. The most suitable anode materials are ruthenium oxides based titanium or alloy of titanium. It is necessary to develop Ti or Ti/TiO2 electrodes and promote their application in the future.
