The cathodic decomposition of propylene carbonate in lithium batteries

Abstract Cathodic decomposition of propylene carbonate (PC) on the graphite electrode in lithium batteries is investigated galvanostatically and potentiostatically. A new reaction process of PC decomposition is proposed, in which the PC decomposition reaction completes with the formation of the lithium intercalated compound (GIC). The process is also argued theoretically and experimentally. Many experimental results support this process.
