PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery that can be used for a long period. SOLUTION: This battery is composed of a positive pole 21, capable of absorbing and discharge lithium, a negative pole 22 made of a substance capable of absorbing and discharging a lithium metal, a lithium alloy or lithium or a conductive substance, a separator 3 provided between both poles, a non- aqueous electrolyte 1 impregnated in the separator 3, and a battery container 5. In this case, non-aqueous electrolyte contains a heteroocyclic compound, made of one or two types to be selected from a group of triazine and its derivative, 2-(2-benzo triazol)-P-cresol and its derivative or coumarine and its derivative. The negative pole 22 is preferably surface-treated with a treatment liquid containing the above heterocyclic compound. |
