Abstract
A method of making a negative electrode, the electrode made thereby and a secondary electrochemical cell using the electrode. Lithium, silicon and nickel is alloyed in a prescribed proportion forming an electroactive material, to provide an improved electrode and cell.
Claims8
A negative electrode composition comprising a ternary alloy consisting essentially of alloyed to a silicon-nickel substrate, lithium being in a range of from about 0.1 to about 70 atom percent, silicon being in a range of from about 17 to about 57 atom percent, and nickel being in a range of from about 13 to about 43 atom percent.
A secondary electrochemical cell having a positive electrode and a negative electrode, and an electrolyte, said positive electrode comprising a ternary alloy composition consisting essentially of an active material of a transition metal chalcogenides, said negative electrode comprising a formed particulate of a lithium alloy on a silicon and nickel substrate, and said electrolyte comprising lithium and halide ions providing ionic communication between said positive and negative electrodes.
