Abstract
The negative electrode of an electrochemical cell with lithium as the electroactive species includes a metal silicide. This metal silicide can be an alloy (that is, a multimetallic silicide) that reacts with lithium and acts as a reversible lithium reservoir during cell operation. Electrochemical cells in accordance with the invention have excellent kinetics and higher theoretical specific energy that the Li-Si binary alloys presently used in some thermal batteries. Magnesium silicide, calcium silicide and molybdenum silicide are particularly preferred materials for these negative electrodes due to their thermodynamic properties.
