Abstract

We report a simple and scalable synthesis of MnSe₂ nanocubes as the Na-ion battery anode materials. The as-prepared MnSe₂ nanocubes electrode achieves a four-electron reaction with an enhanced reversible capacity 249 mAh g⁻¹ at 0.1 A g⁻¹ and a 90.8% capacity retention after 100 cycles, which could be attributed to the particle-size decreasing from micrometer to nanometer scale and the usage of diglyme-based electrolyte. This work envisions the great potential of nano-sized metal selenides toward Na⁺ ion storage.
