## Summary

The demand for renewable resources and electric vehicles is increasing as non-renewable resources become unsustainable. To meet this demand, better batteries are essential to stabilize the evolving energy landscape. Understanding and monitoring the fundamental mechanisms that govern battery operation throughout its life cycle is crucial for maximizing performance and longevity. However, current knowledge of a commercial battery's health status is limited to basic measurements such as current, voltage, temperature, and impedance. Operando characterization techniques have emerged as a way to track commercial battery properties under realistic conditions, providing valuable chemical, thermal, and mechanical data that can revolutionize the development and utilization strategies of lithium-ion devices. These techniques include electrical sensors, optical fibers, acoustic transducers, X-ray-based imaging, and thermal imaging using IR cameras or calorimetry. By utilizing these non-destructive operando characterization techniques, researchers can gain a deeper understanding of degradation mechanisms, reduce time and cost associated with battery testing, and enhance overall battery performance throughout its entire life cycle. This review explores the latest advances in these techniques and their potential to improve the comprehension of battery behavior over time. The authors Charlotte Gervillie-Mouravieff, Wurigumula Bao, Daniel A Steingart, and Ying Shirley-Meng provide valuable insights into how these methods can contribute to the sustainable development of energy storage solutions for the future.
