Dual-ion batteries are emerging energy storage devices with dual-ion-involved charge mechanisms. In this work, we have proposed SnO2 as an anode for dual-ion battery (DIB) applications a restricted potential window (<1 V vs. Li/Li+). More importantly, the choice of electrolyte will be ethylene carbonate-free solvents, known their film-forming abilities. Unfortunately, it hinders anion intercalation into graphitic structures. Fluoroethylene carbonate (FEC) has been used additive, which allows...
