PROBLEM TO BE SOLVED: To provide a secondary battery that restrains degradation of nonaqueous electrolyte by suppressing the effect of HF in the nonaqueous electrolyte and improves cycle characteristics. SOLUTION: The lithium secondary battery is equipped with an electrode body 1, which is wound or laminated with a positive electrode plate 2 and a negative electrode plate 3 having a separator in-between, and uses a nonaqueous electrolyte containing lithium compound as an electrolyte. Three dimensional siloxane compound is contained in one of the positive electrode plate 2, negative electrode plate 3, separator 4 or the nonaqueous electrolyte. |
