摘要

镁锂混合离子电池是一种具有快速离子迁移动力学和高安全性的潜在储能装置。采用一步溶剂热法制备网状微花制备CoSe2，网状微花可以为离子扩散提供更短的路径，并为电化学反应过程中的体积变化提供缓冲空间。放电比容量在1 A g-1下循环500次后保持在361.9 mAh g-1。此外，它还具有较高的倍率性能，在0.2 A g-1时的放电容量为452.0 mAh g-1，在2 A g-1时的放电容量为332.0 mAh g-1。该研究证实了CoSe₂是高性能镁锂混合离子电池的合适正极材料。

One step construction of Mesh-like CoSe2 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. The CoSe2 were prepared using one-step solvothermal preparation of mesh-like microflowers, which can provide shorter paths for ion diffusion and can provide buffer space for volume changes during electrochemical reactions. The discharge specific capacity is maintained of 361.9 mAh g-1 after 500 cycles at 1 A g-1. In addition, it has high rate performance with 452.0 mAh g-1 discharge capacity at 0.2 A g-1, and has 332.0 mAh g-1 discharge capacity at 2 A g-1. This work confirms that CoSe₂ is an appropriate cathode material for high performance Magnesium-lithium hybrid-ion batteries.
