ELECTROLYTIC SOLUTION AND SECONDARY LITHIUM BATTERY CONTAINING THE SAME

摘要

PURPOSE: An electrolytic solution is provided to improve stability of a battery by forming a conductive high polymerized film on an anode surface so as to interrupt over current. CONSTITUTION: An electrolytic solution for a secondary lithium battery is obtained by adding a monomer of conductive high polymers to non-soluble solvent. The monomer of conductive high polymers is one selected from a group of pyrrole, aniline, thiophene and derivate thereof, which are electrically chemically before and after 4V against lithium potential. The non-soluble solvent is an organic solvent such as cyclic or chain carbonate.
