Electrochemical cell and negative electrode therefor
A secondary electrochemical cell is disclosed with the positive and negative electrodes separated by a molten salt electrolyte with the negative electrode comprising a particulate mixture of lithium aluminum alloy and electrolyte and an additive selected from graphitized carbon, raney iron or mixtures thereof. The lithium aluminum alloy is present in the range of from about 45 to about 80 percent by volume of the negative electrode, and the electrolyte is present in an amount not less than about 10 percent by volume of the negative electrode. The additive of graphitized carbon is present in the range of from about 1 to about 10 percent by volume of the negative electrode, and the raney iron additive is present in the range of from about 3 to about 10 percent by volume of the negative electrode.
