ABSTRACT The development of high‐performance energy storage systems requires several key attributes, including high and power density, cost‐effectiveness, safety, environmental sustainability. Among the various potential technologies, lithium–sulfur batteries stand out as a promising contender for future solutions due to their exceptional theoretical specific density (2600 Wh kg⁻¹) relatively capacity (1675 mAh g⁻¹). However, commercialization faces significant challenges, such low sulfur loading, rapid degradation, poor cycling stability. At heart these issues lies limited understanding complex conversion chemistry involved in batteries. In recent years, progress has been made elucidating reaction mechanisms, thanks use both ex situ characterization techniques. Methods optical spectroscopy, time‐of‐flight secondary ion mass spectrometry, synchrotron X‐ray, neural network analysis have demonstrated great uncovering redox processes lithium polysulfides underlying significantly advancing research battery systems. This review focuses on major advancements research, particularly study electrocatalytic mechanisms using emerging We discuss aspects accurately revealing through advanced diagnostic methods, well main challenges techniques face. Finally, we explore prospects commercialization.

Abstract At present, electronic devices such as electric vehicles and mobile phones have increasing requirements for battery energy density. Lithium–sulfur batteries (LSBs) a high theoretical density are considered potential choice realizing the next generation of (2600 W h kg −1 ) batteries. However, actual LSBs is much lower than due to poor conductivity sulfur, serious LiPSs shuttle, low sulfur utilization, so on. Many lightweight materials characterized by surface area designability. The reasonable design modify can reduce proportion inactive substances optimizing electrochemical performance, which crucial improving LSBs. few reviews discuss effect on from perspective whole system. Herein, application in six aspects: liquid electrolyte, solid cathode, anode, separator, current collector discussed. significance use further improvement summarized prospected.
