| abstract |
Object: To provide a battery negative electrode material exhibiting both a merit of high specific capacity obtained by using Si, and a merit of high cycle durability obtained by using a non-graphitizable carbon material. n Resolution Means: A negative electrode material ( 1 ) of a battery of the present invention includes silicon material areas ( 10 ) made of a silicon material, and a carbon material area ( 20 ) made of a carbon material. The carbon material area ( 20 ) is formed in a surrounding area of the silicon material area ( 10 ), separated by a cavity ( 30 ) at least at a portion. In addition, an (002) average interlayer spacing d 002 of the carbon material area ( 20 ) determined by powder X-ray diffraction is from 0.365 nm to 0.390 nm. The battery negative electrode material 1 is manufactured through: a step (a) of melting and mixing or dissolving and mixing with an organic material composition, a coated silicon material that has been coated with silicon oxide; a step (b) of removing the silicon oxide; and a step (c) of carbonizing an organic material constituting the organic material composition. |
