In a nonaqueous electrolyte secondary cell having positive and negative electrodes made of a material capable of doping and removing (de-doping) lithium and a nonaqueous electrolyte prepared by dissolving an electrolyte in a nonaqueous solvent, flake-like graphite which is highly crystalline and has high electron conductivity is added as a conductor agent to the positive and negative electrodes. In addition to this flake-like graphite, granular carbon having specific physical properties or carbon black is added as the conductor agent. As a result, a nonaqueous electrolyte secondary cell having a long cycle life and a high reliability can be obtained. |
