发明名称 LITHIUM SECONDARY BATTERY
摘要 <P>PROBLEM TO BE SOLVED: To suppress deterioration of battery characteristics of various kinds in storage under high temperature conditions by improving a non-aqueous electrolyte in a lithium secondary battery which is provided with a positive electrode, a negative electrode, and the non-aqueous electrolyte prepared by dissolving a solute in a non-aqueous solvent. <P>SOLUTION: The lithium secondary battery is provided with the positive electrode 1, the negative electrode 2, and the non-aqueous electrolyte. Lithium salt having an oxalato complex as anion is admixed into the non-aqueous solvent with at least one film forming agent selected from a group consisting of vinylene carbonate, vinyl ethylene carbonate, ethylene salfite, and fuluoroethylene carbonate. <P>COPYRIGHT: (C)2006,JPO&NCIPI
