摘要:PROBLEM TO BE SOLVED: To provide a lithium ion secondary battery in which the probability of self discharge is reduced even when a very minute amount of metal powder is mixed therein.SOLUTION: In a lithium ion secondary battery, a separator including a modified spot where Raman peaks corresponding to a C=C stretch and a C-C stretch in a conjugate system are observed is used. The modified spot is preferably provided on a negative electrode side of the separator. The negative electrode may include a metal-made projecting portion at a position corresponding to the modified spot of the separator.SELECTED DRAWING: Figure 2
