The optimization of batteries is a challenge for sustainable human development. Batteries have played pivotal role in reducing greenhouse gas emissions across diverse sectors, including light and heavy transportation, power generation, stationary energy storage, industrial processes, thereby mitigating environmental pollution. Despite these advancements, comprehensive understanding battery operational processes remains elusive. Critical aspects, such as reaction mechanisms, side reactions, ion transport, the formation solid electrolyte interphases (SEI) are still not fully elucidated. Recently, with continuous improvement synchrotron-related technology, advantages X-ray absorption spectroscopy (XAS) research materials become more prominent, providing an important skill materials. This review focuses on application XAS lithium-ion (Li-ion) batteries, all-solid-state (ASSBs) lithium–sulfur (Li–S) demonstrates key analyzing interface changes between electrode electrolytes optimizing performance. Moreover, technology enables researchers to monitor structural chemical state under real-world operating conditions real time, theoretical basis development safer, environmentally friendly, cost-effective significant progress made by study materials, challenges remain, difficulty capturing fast dynamic time. In future, advances will need be further developed conjunction other characterization methods gain deeper insights.
