A high-rate free-standing Na3V2(PO4)3 symmetric full cell for sodium-ion batteries†
Abstract
Na3V2(PO4)3 nanoparticles are encapsulated in carbon nanofibers (NVPCNF), and the electrochemical properties of the cathode, anode and full cell are studied. A low viscous-high ionic conductivity dimethoxyethane-based electrolyte is deployed to boost the kinetics, resulting in excellent electrochemical performances.
