Building rechargeable batteries for subzero temperature application is highly demanding for various specific applications including electric vehicles, grid energy storage, defense/space/subsea explorations, and so forth. Commercialized nonaqueous lithium ion batteries generally adapt to a temperature above −20 °C, which cannot well meet the requirements under colder conditions. Certain improvements have been achieved with nascent materials and electrolyte systems but have mainly been restrained to discharge and within a small rate at temperatures above −40 °C. Moreover, the recharging process of batteries based on the graphite anode still faces huge challenges from the simultaneous Li⁺ intercalation and potential Li stripping at subzero temperatures. Revealing the temperature-dependent evolution of physicochemical and electrochemical properties will greatly benefit our understanding of the limiting factors at low temperature, which is of significant importance.

推广低温充电电池

构建用于零下温度应用的可充电电池对各种特定应用（包括电动汽车、电网储能、国防/太空/海底探索等）的要求很高。商业化的非水锂离子电池一般适应-20℃以上的温度，在较冷的条件下不能很好地满足要求。新生材料和电解质系统已经取得了某些改进，但主要是限制在-40°C以上的温度下放电和小速率。此外，基于石墨阳极电池充电过程中仍然面临着来自同时李巨大挑战⁺零下温度下的嵌入和潜在的锂剥离。揭示物理化学和电化学性质的温度依赖性演变将极大地有助于我们理解低温下的限制因素，这具有重要意义。
