Despite the inherent long cycle life of Li−S batteries under normal operating conditions, ensuring their stable performance in extreme temperatures, particularly below 0 °C and above 60 °C, is imperative for expanding their application range. This review aims to comprehensively summarize recent advancements in the field of Li−S batteries, with a primary focus on their electrochemical performance and longevity under extreme temperature conditions.

Abstract

In electrochemical energy storage (EES), lithium-sulfur (Li−S) batteries have recently gained recognition for their exceptional theoretical specific capacity, making them stand out among a wide range of cutting-edge energy storage technologies. While Li−S batteries demonstrate a long cycle life under regular conditions, expanding their application scenarios is crucial for their future development. Specifically, ensuring stable battery operation in extreme temperature environments, such as below 0 °C and above 60 °C, becomes paramount. Thus, this review aims to summarize the recent progress of Li−S batteries in extreme temperature ranges and analyse the processability of critical materials within these batteries at extreme temperatures. Ultimately, this review presents insights and potential prospects for Li−S battery systems operating within a wide temperature range, contributing to advancing energy storage devices capable of functioning across various temperatures.
