Seeking for superior electrode materials is a significant project in lithium-ion battery research interests. In this paper, pure MnSe was synthesized via a simple hydrothermal method, which exhibits high crystalline and lamellar plate microstructure by systematical characterization analysis. Further, the as-synthesized MnSe was investigated for electrochemical performance as anode material of lithium-ion battery via correlative measurements. In the half-cell tests, the MnSe lithium-ion battery has delivered large specific capacity (302.7 mAh g −1 at 0.2 C), proper voltage platform, excellent rate performance, satisfactory reversibility, and outstanding ionic conductivity. It should be noted that the capacity retention of battery can reach up to 70.8% even after 3000 times cycle at 5.0 C current density, demonstrating remarkable cycle stability. This work not only reveals superior performance of MnSe materials from a different perspective but also provides a potential practical candidate for lithium-ion battery anode.
