Abstract
A chargeable lithium secondary cell comprising a positive electrode composed mainly of vanadium pentaoxide, a negative electrode of a compound of lithium with niobium pentaoxide and an electrolyte of an organic solvent in which a lithium salt is dissolved, wherein resistance to overdischarge is obtained by a constitution that the molar ratio of the niobium pentaoxide to vanadium pentaoxide is from not less than 0.5 to not more than 1 and the molar ratio of the total litium contained in the positive and negative electrodes to vanadium pentaoxide is from not less than 1.1 to not more than 2.
