Abstract
A lithium secondary batteryis configured such that an electrode body, in which a cathode and an anode are stacked via a separator impregnated with an electrolyte, is housed in a battery casehaving a substantially cylindrical square shape and that an openingof the caseis blocked by a lidFurther, the lidis provided with a cathode terminaland an anode terminaland such terminals are respectively connected, inside the battery caseto an internal cathode collection terminaland an internal anode collection terminalA non-aqueous electrolyte used for the lithium secondary batterycontains, as a specific compound, for example, LiBOB, and an initial content of such specific compound relative to a capacitance of the anode is 0.04 to 0.5 [(mol/kg)/(mF/cm)].
