Abstract
A mixed carbon material is useful for an electrode of a nonaqueous secondary battery. The material has two component materials: carbon material A and carbon material B. Both materials have high capacity and rapid charge-discharge characteristics. Carbon material A, a multilayer-structure material containing an amorphous carbon covering the surface of a graphitic particle, has particularly excellent charging-discharging properties. Carbon material B has particularly excellent electrical conductivity properties. A battery with an electrode having the mixed carbon material can have both rapid charge-discharge characteristics and high cycle characteristics.
