Improved Na⁺/K⁺ Storage Properties of ReSe₂-Carbon Nanofibers Based on Graphene Modifications.

ABSTRACT: Rhenium diselenide (ReSe₂) has caused considerable concerns in the field of energy storage because the compound and its composites still suffer from low specific capacity and inferior cyclic stability. In this study, ReSe₂ nanoparticles encapsulated in carbon nanofibers were synthesized successfully with simple electrospinning and heat treatment. It was found that graphene modifications could affect considerably the microstructure and electrochemical properties of ReSe₂-carbon nanofibers. Accordingly, the modified compound maintained a capacity of 227 mAh g^-1 after 500 cycles at 200 mA g^-1 for Na⁺ storage, 230 mAh g^-1 after 200 cycles at 200 mA g^-1, 212 mAh g^-1 after 150 cycles at 500 mA g
