Abstract:

The principle and classification of overcharge protection additives for lithium ion secondary batteries are described. The redox shuttle additives consist of metallocene compounds，polypyridine complexes，thiophene anthracene and derivatives，fennel benzene and derivatives，and anisole and its derivatives. The electric polymer additives consist of biphenyl，cyclohexyl benzene，esters and derivatives，and N-phenyl. The overcharge protection mechanism and research progress of these two types of additives are introduced. The development of overcharge protection additives is discussed.
