    Abstract: The present invention relates to a negative material for a non-aqueous rechargeable battery and a non-aqueous rechargeable battery including the same. The negative material for a non-aqueous rechargeable battery includes lithium vanadium oxide that is obtained by mixing a lithium compound such as lithium carbonate (Li2CO3) and a vanadium compound such as vanadium pentaoxide (V2O5) with an organic acid such as oxalic acid ((COOH2) to obtain an organic acid salt precursor and firing the organic acid salt precursor. The negative material for a non-aqueous rechargeable battery can improve charge and discharge characteristics of a non-aqueous rechargeable battery due to uniform composition.
