Lithium-ion batteries are currently the most widely used rechargeable batteries due to the excellent properties. Transition metal nitrides are expected to be used as efficient anode materials for lithium-ion batteries benefiting from their low and flat charging-discharging plateau, good reversibility and high capacity. This paper aims to review the research progress on transition metal nitrides and their composites synthesized by physical and chemical methods for applications of lithium-ion batteries. The key issues existed in transition metal nitrides and the viable route to improve the performance of transition metal nitrides based lithium-ion batteries are also discussed.
