ABSTRACT:
A highly safe non-aqueous electrolyte secondary cell with excellent self-extinguishing property or flame retardancy is provided which comprises an anode, a cathode, a non-aqueous electrolyte in which an Li-salt as a supporting salt is dissolved in an organic solvent, and a separator. When a high crystalline carbon material such as graphite is used as cathode active substances, it is possible to provide a non-aqueous electrolyte secondary cell whose charging/discharging life is lengthened, whose interface resistance at the non-aqueous electrolyte can be reduced, and which has excellent discharging characteristics at low temperature.
