1D MnSe@carbon nanofiber as a high-rate anode for sodium-ion batteries: electrochemical and ex situ mechanistic investigation of Na+ charge storage

1D MnSe@CNF was synthesized by means of an electrospinning technique. The MnSe@CNF anode exhibited an enhanced specific capacity of 725 mA h g −1 . The deconvolution of the cyclic voltammetry profiles revealed that Na + charge storage was a blend of diffusion and significant capacitive storage.
