PURPOSE:To prevent collapse and to increase strength by forming a lithium- aluminum alloy electrode useful as a negative electrode for nonaqueous secondary battery by mixing lithium-aluminum alloy powder with aluminum powder, then press-molding the mixture. CONSTITUTION:Lithium-aluminum alloy powder having a particle size of 200-500 mesh obtained by sieving is uniformly mixed with 5-20wt% aluminum powder. The mixture is filled in a mold having a shape of electrode and pressed at room temperature, or at a temperature lower than the melting point of aluminum powder but higher than room temperature to manufacture a lithium- aluminum alloy electrode used for a negative electrode of nonaqueous secondary battery. By use of aluminum powder, binding action is increased to strengthen the electrode so as to be free from collapse. Therefore, a secondary battery having high energy density and high charge-discharge efficiency is obtained. |
