Abstract
- Abstract MnSe and Co0.85Se embedded in nitrogen‐doped carbon nanofibers (MnSe/Co0.85Se/N‐CNFs) were synthesized by electrospinning and high‐temperature calcination, and evaluated for the first time as sodium/potassium‐ion battery anode material via constant current charge/discharge, cyclic voltammetry, electrochemical impedance spectroscopy.Ex‐situ XRD revealed the potassium storage mechanism of MnSe/Co0.85Se/N‐CNFs, indicating that its capacity was mainly provided by the conversion reaction. Compared with MnSe/N‐CNFs and Co0.85Se/N‐CNFs, the reversible capacity and cycling performance of MnSe/Co0.85Se/N‐CNFs were significantly improved due to the synergistic effect of bimetals. The MnSe/Co0.85Se/N‐CNFs electrode showed a charging capacity of 262.3 mAh g−1 after 700 cycles at 1 A g−1 in Na‐ion batteries and a discharge capacity of 183.4 mAh g−1 after 400 cycles at 0.1 A g−1 in K‐ion batteries, The results showed that binder‐free binary metal MnSe/Co0.85Se/N‐CNFs have a certain development prospect as anode for sodium/potassium‐ion batteries.
