PROBLEM TO BE SOLVED: To provide a high capacity lithium secondary battery whose cycle service life is long and which uses intercalative reaction and deintercalative reaction of a lithium ion as charge-discharge reaction. SOLUTION: A lithium secondary battery is composed of at least a negative electrode 101, a separator 104, a positive electrode 102, electrolyte 103, a current collecting electrode and a battery case 107. The electrolyte is composed of salt of an organic fluorine-silicon compound containing at least a silicon element, a fluorine element and a carbon element. |
