<P>PROBLEM TO BE SOLVED: To provide a battery with cycle characteristics improved. <P>SOLUTION: Electrolyte solution is provided together with a cathode 21 and an anode 22, and a separator fitted between the cathode 21 and the anode 22 has the electrolyte solution impregnated. The anode 22 is provided with an anode collector 22A, an anode active material layer 22B provided at the anode collector 22A, and a coating 22C provided at the anode active material layer 22B. The coating 22C contains hexafluoride di-lithium zirconate, and is formed by a dipping treatment or a coating treatment using solution containing the same. Since chemical stability of the anode 22 is improved, decomposition of the electrolyte solution is restrained as compared with the case in which no coatings 22C are provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
