[Object] The object is to provide a negative
electrode material for a
lithium secondary battery, wherein a
sulfide-based negative
electrode with water-resistant properties can exert excellent cycle characteristics and high output performance while maintaining a high
discharge capacity and there is no
precipitation of
lithium dendrites during charge at low temperature.[Means for Solving Problems] A negative
electrode material for a
lithium secondary battery comprising
sulfur and
sulfide glass including the following components (i) and (ii):(i) at least one or more elements selected from a group consisting of Sb, As, Bi, Ge, Si, Cu, Zn, Pd, In and Zr; and(ii) at least one or more elements selected from a group consisting of Se, Te, Ga, Sn, Pb, Cd, Al, Fe, Mg, Ca, Co, Ag, Sr, P and Ba,wherein the ratio of the above components is
sulfur: 40-80 mol %, (i): 1-50 mol % and (ii): 1-50 mol %, respectively.
