Abstract Lithium‐ion batteries (LIBs) and sodium‐ion (SIBs) have recently received considerable attention in electrical energy storage (EES) systems due to their sustainability, high density, superior conversion efficiency. However, with the expansion of application scenarios, ability operate under extreme conditions, especially low temperatures, is becoming increasingly important. Therefore, extending operating temperature electrochemically stable safe LIBs SIBs has become a critical research topic. In this review, failure mechanism conditions at same time problems faced by electrolyte electrode materials are discussed, various targeted optimization strategies proposed. Additionally, performance such environments compared, drawing an instructive understanding. Finally, summary perspective presented for improving battery electrochemical respectively. Overall, review aims provide design guidelines future conditions.
