The active material contains LixNiyMzO2 (0.8<x<1.5, 0.8<y+z<1.2, 0≤z<0.35; M is at least one element selected from Co, Mg, Ca, Sr, Al, Mn and Fe) having a half-value width in a range of 2.0 to 50 mu m at an average particle diameter of its particle size distribution. The binder is fluorine rubber or polyvinylidene fluoride. The electrically conductive agent is graphite when the binder is polyvinylidene fluoride. <IMAGE> |
