FIRE RETARDANT ELECTROLYTIC SOLUTION AND SECONDARY LITHIUM BATTERY CONTAINING THE SAME

摘要

PURPOSE: A fire retardant electrolytic solution for a secondary lithium battery is provided to improve the stabilization of a battery by adding a phosphoric acid solvent to a carbonate solvent. CONSTITUTION: In a fire retardant electrolytic solution for a secondary lithium battery, a phosphoric acid solvent is mixed with a carbonate solvent containing no oxygen. A non-organic addition such as a metal oxide or a metal halogen chemical combination is added. The carbonate solvent is cyclic or chain carbonate.
