CARBON MATERIAL, PRODUCTION METHOD AND USE THEREOF |
摘要 |
A carbon material includes carbon particles having a graphite structure, the particles having a carbonaceous material deposited on at least a portion of the surface thereof, and fibrous carbon. In the carbon material, the carbonaceous material is obtained by subjecting a composition containing a polymer to heat treatment. The fibrous carbon is preferably deposited to the carbon particles through a carbonaceous material obtained by subjecting a composition containing a polymer. As a result, when the carbon material is used as a negative electrode active material for a secondary battery, the electrical conductivity can be improved and large current load enduring characteristics and cycle characteristics can be improved. By coating the carbonaceous material onto the carbon particles having a graphite structure, destruction of the graphite structure by the polyethylene carbonate-based electrolytic solution can be prevented. |
