<P>PROBLEM TO BE SOLVED: To provide a secondary battery aiming at a longer life. <P>SOLUTION: The secondary battery 10 has its power generating element 109 housed and sealed in outer package members 106, 107, and a cathode terminal 104 connected to a cathode plate 101 and an anode terminal 105 connected to an anode plate 103 are led out from the outer package members 106, 107. The power generating element 109 is provided with an electrode plate containing the anode plate 103 having an anode mixture in which two kinds of graphitization-retardant carbon materials having capacity different from each other are mixed with a binder such as PVDF and dispersed in a solvent such as NMP coated on an anode side current collector 104a. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
