<P>PROBLEM TO BE SOLVED: To provide a carbon electrode of improved charge and discharge reactivity. <P>SOLUTION: The carbon electrode for a polymer battery contains polymers having polarity, lithium salts, and hard-carbon particles to which lithium ions are charged and discharged by electric charging and discharging. The surfaces of the hard-carbon particles 11a and 11b are at least partly coated with easily graphitized carbon or graphitic carbon 13a, 13b. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
