摘要:
A lithium secondary battery comprising a positive electrode, a negative electrode, and a nonaqueous electrolyte, wherein the positive electrode or the negative electrode is an electrode obtained by depositing a thin film of active material capable of lithium storage and release on a current collector, the thin film is divided into columns by gaps formed therein in a manner to extend in its thickness direction and the columnar portions are adhered at their bottoms to the current collector, and the nonaqueous electrolyte contains at least one selected from phosphate ester, phosphite ester, borate ester and carboxylic ester having a fluoroalkyl group.
