Abstract

A collaborative manipulation strategy of proper heat treatment and self-customized hydrofluoroether-based electrolyte design has been proposed for boosting the sodium-ion storage kinetics of Prussian white cathodes. Improved monoclinic phase stability and electrolyte–cathode compatibility are responsible for an impressive discharge capacity of 148.4 mA h g⁻¹ and excellent electrode reversibility.
