<P>PROBLEM TO BE SOLVED: To provide a battery capable of improving cycle property. <P>SOLUTION: A cathode active substance layer 12 is formed by forming a precursor layer containing active substance particles 12A containing Si and Li as constitutional elements, and heating it afterwards. By the above, the active substance particles 12A are sintered, fused, and stuck to each other, and three-dimensionally integrated. The active substance layer can be sufficiently sintered at a low heating temperature of 600°C by the lithium contained. The precursor is formed by making the precursor absorb lithium evaporated, after making a cathode current collector carry Si particles. <P>COPYRIGHT: (C)2007,JPO&INPIT |
