New development of anode in lithium-ion batteries

Electrode material plays a key role in the manufacture and application of lithium ion batteries. The development of high performance lithium ion batteries mainly depends on the new anode materials. Research on lithium ion batteries focus on modifing commercialized anode material and developing new anode material. The latest studies on anode materials for lithium ion batteries were reviewed ,including lithium alloys, transition metal nitrides, and transition metal phosphides. The charge/discharge reaction mechanisms and electrochemical performances of alloys were discussed specially. The developing trend of the anode material was prospected and the most promising anode material for lithium ion batteries was also proposed. The results show that commercialization of alloys is the key to enhancing the capacity of lithium ion batteries.
