Improvement of Interphase Stability of Hard Carbon for Sodium-Ion Battery by Ionic Liquid Additives

Improvement of Interphase Stability of Hard Carbon for Sodium-Ion Battery by Ionic Liquid Additives

Hard carbon (HC), which is one of the anode materials widely used in commercial sodium-ion batteries at present, suffers from a thick and unstable solid electrolyte interface (SEI) layer formed by the self-reduction in traditional carbonate-based electrolytes on its surface. This phenomenon impacts...
