Abstract
The lithium secondary battery of this invention uses a nonaqueous electrolyte including lithium tetrakis(pentafluorophenyl)borate as a part or whole of an electrolytic salt. As a result, the lithium secondary battery exhibits better charge-discharge cycle performance than a lithium secondary battery using a conventional lithium salt as the electrolytic salt.
Claims7
