Lithium secondary battery.

摘要

A lithium secondary battery which comprises a positive electrode made of vanadium pentoxide as a principle component, a negative electrode made of lithium absorbing alloy, and an electrolyte prepared from an organic solvent dissolved with lithium salt. The lithium absorbing alloy is an allow containing aluminum as a principle component, and the amount of lithium absorbed by the alloy is not greater than 8 wt% relative to the weight of the vanadium pentoxide and not smaller than 4 wt% relative to the alloy containing the aluminum as the principal component.
