Hollow-Structured Carbon-Coated Co<sub>x</sub>Ni<sub>y</sub>Se<sub>2</sub> Assembled with Ultrasmall Nanoparticles for Enhanced Sodium-Ion Battery Performance

Transition metal selenides are considered one of the most promising materials for sodium-ion battery anodes due to their excellent theoretical capacity. However, it remains challenging to suppress the volume variation and the resulted capacity decay during the charge–discharge process. Herein, hollo...
