One-step construction of mesh-like CoSe <sub>2</sub> microflowers for magnesium–lithium hybrid batteries with enhanced rate performance
Magnesium-lithium hybrid-ion batteries are a potential energy storage device possessing fast ion migration kinetics and high safety. A CoSe<sub>2</sub> was prepared using a one-step solvothermal preparation of mesh-like microflowers, which can provide shorter paths for ion diffusion and buffer space for volume changes during electrochemical reactions. The discharge specific capacity is maintained at 361.9 mAh g<sup>-1</sup> after 500 cycles at 1 A g<sup>-1</sup>. In addition, the CoSe<sub>2</sub> has a high-rate performance, with 452.0 mAh g<sup>-1</sup> discharge capacity at 0.2 A g<sup>-1</sup>, and a 332.0 mAh g<sup>-1</sup> discharge capacity at 2 A g<sup>-1</sup>. This work confirms that CoSe<sub>2</sub> is an appropriate cathode material for high-performance magnesium-lithium hybrid-ion batteries.
