Multi-anion high-entropy electrolytes enabling lithium-ion batteries with enhanced voltage tolerance and wide-temperature operability

Year: 2025

Type: article

Abstract: To achieve high-voltage stability and low-temperature performance simultaneously in lithium-ion batteries, a high-entropy electrolyte with multi anions is proposed. The multi anions not only lows the solvation-free energy, but also contributes to the formation of inorganic-rich CEI layer. The optimized electrolyte enables stable cycling of NCM523 at both 25 °C and -20 °C.
