Abstract

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.
