<P>PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery with good discharging capacity, high efficiency discharge characteristic and cycle characteristic. <P>SOLUTION: In the non-aqueous electrolyte secondary battery, a positive electrode 3 containing LiCoO<SB>2</SB>with the surface coated by LiNiO<SB>2</SB>or manganic acid lithium, a cathode 4 containing cathode active material and non-aqueous electrolyte containing ester of cyclic carboxylic acid are provided. In the non-aqueous electrolyte secondary battery, LiCoO<SB>2</SB>is used in nuclei of anode active material and by covering the surface with LiNiO<SB>2</SB>or manganic acid lithium, the deterioration of the activity of LiCoO<SB>2</SB>is suppressed and the cycle characteristic, etc., are improved. <P>COPYRIGHT: (C)2004,JPO |
