ABSTRACT:
This invention relates to lithium-germanium containing electrodes for electrical energy storage batteries, batteries containing such electrodes and a process for fabrication of such electrodes from materials in the charged and uncharged state. The electro-chemically active material may be a binary alloy of lithium-germanium or ternary alloys of lithium-germanium-silicon and lithium-germanium-aluminum. Negative electrodes for electrical storage batteries fabricated according to this invention provide batteries having improved stability over prior art lithium containing electrodes and provides a particularly advantageous negative electrode for use in lithium-metal sulfide batteries having improved stability.
