Facile preparation of bimetallic cobalt-copper selenide nanosheets as stable cathode materials for rechargeable magnesium batteries
Source abstract
Abstract
The pursuit of novel cathode materials with excellent performance is the key to promoting the application of rechargeable magnesium batteries (RMBs). Herein, bimetallic copper-cobalt selenide (CuCo 2Se 4) as a cathode material for RMBs, synthesized via a microwave-assisted method. In contrast to the monometallic selenide (Co 0.85Se), CuCo 2Se 4 exhibits a high reversible capacity of 108 mAh g −1 at 50 mA g −1 after 80 cycles, and a superior rate capability (90 mAh g −1 at 200 mA g −1 ). The crystal phase transition of the conversion electrode material during the cycles is analyzed using ex-situ XRD technology. The enhanced stability of bimetallic selenide provides a good experimental support for the preparation of high-performance rechargeable magnesium batteries based on bimetallic strategy.
