Abstract

A rechargeable lithium/chlorine (Li/Cl₂) battery is a promising candidate for energy storage applications. However, the highly corrosive thionyl chloride (SOCl₂) solvent in the conventional electrolyte has hindered their practical production and application. Here, we discover that methyl chlorodifluoroacetate (MCDFA), a mild ester, can serve as an effective alternative to SOCl₂ to solve the above challenge. The resultant battery using the MCDFA-based electrolyte exhibits a wide operation temperature range from −40 °C to 120 °C, a significant enhancement over conventional rechargeable Li/Cl₂ batteries, and is also competitive among state-of-the-art wide-temperature Li metal batteries. Our results offer an effective strategy to address the corrosivity of the SOCl₂-based electrolyte in rechargeable Li/Cl₂ batteries, and open a new avenue for practical and sustainable energy storage applications.

采用酯基电解质的宽温锂/Cl2电池

可充电锂/氯（Li/Cl2）电池是一种很有前途的储能应用。然而，传统电解液中存在的腐蚀性很强的亚硫酰氯（SOCl2）溶剂阻碍了其实际生产和应用。在这里，我们发现氯二氟乙酸甲酯（MCDFA）是一种温和的酯，可以作为SOCl2的有效替代品来解决上述挑战。使用基于mcdfa的电解质的所得电池显示出从- 40°C到120°C的宽工作温度范围，比传统的可充电锂/Cl2电池有显着增强，并且在最先进的宽温度锂金属电池中也具有竞争力。我们的研究结果为解决可充电Li/Cl2电池中socl2基电解质的腐蚀性提供了有效的策略，并为实际和可持续的储能应用开辟了新的途径。
