| description | The invention discloses an electrolyte for improving the cycling stability of hard carbon and application of the electrolyte in an energy storage sodium ion battery, and relates to the technical field of battery electrolytes.The electrolyte for improving the cycling stability of the hard carbon comprises an organic solvent, sodium salt and an electrolyte additive, the molecular formula of the electrolyte additive is Na3AlF6, the mass percentage of the electrolyte additive is 0.1 wt%-2.0 wt%, the mass percentage of the sodium salt is 10 wt%-20 wt%, and the mass percentage of the organic solvent is 80 wt%-90 wt%. The invention aims to design and develop an electrolyte system for forming a stable SEI film on the surface of a hard carbon negative electrode aiming at the poor cycling stability of an existing energy storage sodium battery, so that the cycling stability of the energy storage sodium battery is improved.
