Abstract:
The present invention relates to a negative active material for a lithium ion battery and a lithium ion battery including the negative active material. The negative active material for a lithium ion battery includes a hexagonal lithium vanadium composite oxide including lithium, vanadium, and magnesium. The lithium and the vanadium are included in a mole ratio within a range of 1.15≦Li/V≦1.35, and the magnesium and the vanadium are included in a mole ratio within a range of 0.01≦Mg/V≦0.06. The present invention provides a negative active material for a lithium ion battery having a stable crystal structure, excellent high rate of charge and discharge, and good charge and discharge cycle characteristics.
