<P>PROBLEM TO BE SOLVED: To satisfy both of a charge/discharge cycle property and a large battery capacity. <P>SOLUTION: Since an added organic additive controls a negative electrode active material surface to be active and suppresses increase in an inner impedance by adding the organic additive to a negative electrode mixture layer 12 including an alloy and an inter-metal compound containing lithium capable of enlarging the battery capacity and an element capable of forming the alloy as a negative electrode active material, both of the cycle property and the large battery capacity can be satisfied. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
