Transition metal dichalcogenides have emerged as promising materials in the energy field due to their unique structural arrangement. In this work, ordered flower-like WSe2 nanosheet was successfully synthesized through a simple hydrothermal method and showed excellent performance as a cathode in rechargeable Mg-ion batteries.
Transition metal dichalcogenides (TMDs) have emerged as a promising material in the energy field due to their unique structural arrangement. In this work, ordered flower-like WSe2 nanosheet was synthesized through simple one-step hydrothermal method, and its cathode application for rechargeable Mg-ion batteries was assessed. The WSe2 cathode exhibits a high reversible capacity above 265 mAh g(-1) at 50 mA g(-1), excellent cycling life of 90% initial capacitance that can be ceaselessly harvested for 100 cycles at 50 mA g(-1), and superior rate capability of 70% initial capacitance maintained even at the current density of 500 mA g(-1). This work paves the way for the application of WSe2 cathode in Mg-ion and other rechargeable batteries. (C) 2020 Elsevier Inc. All rights reserved.
