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.
为了在锂离子电池中同时实现高电压稳定性和低温性能，提出了一种含多阴离子的高熵电解质。多阴离子不仅降低了去溶剂化自由能，还有助于形成富含无机成分的固体电解质界面（CEI）层。优化后的电解质能够使NCM523在25℃和-20℃下都能稳定循环。
