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.

Mechanical grinding of graphite, soft carbon coke, or hard carbon over the range of 20-80 hours produces carbon powders which may be incorporated into secondary lithium battery electrodes to yield improved reversible lithium intercalation capacity of up to about 708 mAh/g, thus approximating Li.sub.2 C.sub.6, with irreversible intercalation of only about 328 mAh/g.
