NON-AQUEOUS ELECTROLYTIC SOLUTION AND LITHIUM SECONDARY BATTERY

摘要

A lithium secondary battery excellent in electric capacitance, cyclic characteristics and retention characteristics, and a non-aqueous electrolyte capable of being advantageously used for the production of such a lithium secondary battery. The non-aqueous electrolyte comprises an electrolyte dissolved in a non-aqueous solvent containing cyclic carbonate, chain carbonate and vinylene carbonate, and has a reduction potential with referen ce to lithium of less than 1 volt and/or a minimum mixing amount of an organic chlorine compound; and the lithium secondary battery uses in combination thi s non-aqueous electrolyte and a cathode and an anode consisting of graphite having a crystal face interval (d002) of up to 0.34 nm.
