This invention pertains to a ceramic material that can be used in electrodes for lithium ion secondary batteries. The ceramic material contains Sn, Si, O, and C that contains at least 1 volume% metal-phase Sn wherein the weight ratios among these elements in the ceramic material is Sn 1: Si 0.001 to 100: O 0.001 to 100: C 0.0 01 to 100. This metallic tin is formed by thermal reduction by carbon. |
