PURPOSE:To give high electron conductivity to a positive electrode by small amount of metal and obtain a lithium battery having small internal resistance and large discharge capacity by applying chemical plating of metal to positive active material powder. CONSTITUTION:By applying chemical plating of metal to positive active material powder having poor electron conductivity, high electron conductivity can be given to the active material powder in spite of smaller volume occupation compared with addition of nickel powder. Accordingly, a lithium battery having small internal resistance and large discharge capacity. For example, nickel, chromium, gold, or platinum is used as a metal for applying chemical plating to the positive active material. For example, V2O5, TiO2, V6O13, WO3 or CoO2 is used as the positive active material having poor electron conductivity. |
