Electrochemical cell and negative electrode therefor

A secondary electrochemical cell comprising a positive electrode and a negative electrode and an electrolyte, said positive electrode comprising an active material of a chalcogen or a transition metal chalcogen, said negative electrode comprising a particulate mixture of lithium-aluminum alloy and electrolyte and a material selected from graphitized carbon, an aluminum-iron alloy or mixtures thereof, said lithium-aluminum alloy being present in the range of from about 45 to about 80 percent by volume of the negative electrode, said electrolyte being present in an amount not less than about 10 percent by volume of the negative electrode, said graphitized carbon being present in the range of from about 1 to about 10 percent by volume of the negative electrode, said aluminum-iron alloy being present in the range of from about 3 to about 10 percent by volume of the negative electrode, said electrolyte containing lithium ions providing ionic communication between said positive and negative electrodes.
