Lithium hydride negative electrode for rechargeable lithium batteries

摘要

A lithium battery comprises a negative electrode composition that uses lithium hydride and a second metal. The negative electrode composition is activated by infusing lithium into particles of the second metal hydride to form lithium hydride and the second metal. As the battery is discharged lithium is released from the electrode and the second metal hydride formed. Charging of the battery re-infuses lithium into the negative electrode composition with the re-formation of lithium hydride.
