PROBLEM TO BE SOLVED: To provide a lithium secondary cell which comprises a positive elec trode, a negative electrode, and nonaqueous electrolyte, and the positive elec trode or the negative electrode is an electrode formed by depositing an activator thin film storing/releasing lithium on a current collector 10, and the activator thin film 11 is split into pillar shape by cuts 12 formed in the direction of thick ness, and a bottom part of the pillar shaped part closely contacts the surface 10a of the current collector 11, and charging and discharging property is im proved. SOLUTION: A nonaqueous electrolyte contains at least one kind of compound out of the compounds expressed by general formula: LiBF(C6 H5-p Fp )3 , (in the formula, p represent an integer of 1-5), LiB(C6 H5-q Fq )4 , (in the formula, q represent an integer of 1-5), LiB[C6 H5-r (CF3 )r ]4 , (in the formula, r represent an integer of 1-5), as a solute. |
