Electrolyte solvation structure as a stabilization mechanism for electrodes

Rechargeable batteries with high capacity, power and safety are urgently required for current future technological demands. The solid electrolyte interphase (SEI) layer has a dominant impact on battery cyclability the solvate is key factor that determines SEI layer. In this perspective, we first review recent advances in understanding influences of composition solvation chemistry structure electrolytes seems to be root cause stability electrodes during cell cycling. We then discuss strategy manipulate by adjusting compositions electrolytes, including solvent, salt, concentration additive. Finally, concisely challenges characterizing solvates at electrode|electrolyte interface. This refreshes our factors stable interfaces pursuit high-performance systems.
