The main methods to improve the energy density of lithium-ion battery, including exploiting the high capacity and high dis- charge voltage anode materials or negative materials. The several kinds of typical anode and negative materials with high energy density in recent research progressions were summarized, including anode materials such as multi-electrons reaction material, lithium rich material, the polyanion compounds and LiNi0.5 Mn1.5O4 ; negative materials such as hard carbon, silicon based negative materials and tin based negative materials. The characteristics and the electrochemical behaviors of various materials were introduced, emphasis was placed on the discussion of the typical methods of preparations and recent progress. Finally, the development trend and application prospects of lithium-ion battery with the high energy density were forecasted.
