| 摘要 | An object is to increase the conductivity of an electrode including active material particles and the like, which is used for a battery. Two-dimensional carbon including 1 to 10 graphenes is used as a conduction auxiliary agent, instead of a conventionally used conduction auxiliary agent extending only one-dimensionally at most, such as graphite particles, acetylene black, or carbon fibers. A conduction auxiliary agent extending two-dimensionally has higher probability of being in contact with active material particles or other conduction auxiliary agents, so that the conductivity can be improved. | ||||||
