Abstract:
1. A negative active material for a non-aqueous electrolyte rechargeable battery comprising lithium vanadium oxide having a full width at a half maximum of 0.09 to 0.11 degrees at a (003) plane measured by X-ray diffraction, wherein the lithium vanadium oxide has a formula of Li a M b V c O 2+d wherein 1.0≦a≦1.1, 0≦b≦0.5, 0.5≦c≦1.0, 0≦d≦0.5, b+c=1, and M is an element selected from the group consisting of Mg, Zr, Ti, Cr, Mn, Fe, Co, Ni, Nb, Ta, and combinations thereof prepared by mixing a vanadium compound and a lithium compound subjected to a first firing to obtain Li adding a lithium compound to the Li
