摘要

H_3NOHCl is used for the first time as anode material for lithium-ion batteries. Electrochemical results show that H_3NOHCl with particle size of 4-12 μm can deliver an initial charge capacity of 1018.6 mAh g~(-1), which is much higher than commercial graphite. After 30 cycles, the reversible capacity can be kept at 676.1 mAh g~(-1) at 50 mA g~(-1). Up to 50 cycles, H_3NOHCl still maintains a lithium storage capacity of 368.9 mAh g~(-1). Even cycled at 200 mA g~(-1), H_3NOHCl can deliver a charge capacity of 715.7 mAh g~(-1). It suggests that H_3NOHCl has high lithium storage capacity, excellent cycling stability and outstanding rate performance. Besides, the electrochemical reaction between H_3NOHCl and Li is also investigated by various ex-situ techniques. It can be found that H_3NOHCl irreversibly decomposes into Li_3N and LiCl during the initial discharge process and LiNO_2 can be formed after a reverse charge process.
