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.
