  • Negative electrode for nonaqueous electrolyte solution battery and nonaqueous electrolyte solution battery having the same
    Patent number: 8778541
    Abstract: A negative electrode used for a nonaqueous electrolyte solution battery having nonaqueous electrolyte solution containing lithium ion includes a metal carbon composite material. The metal carbon composite material has a porous carbon material having cavities, and a metal material made of metal to reversibly store or emit lithium ion. The metal material is arranged on a surface of the porous carbon material including inner surfaces of the cavities. The porous carbon material has a mass of 1-65 mass % when the metal carbon composite material is defined to have a mass of 100 mass %.
