Photocathode Design in Photo‐Assisted Li‐O2 Batteries: Status and Perspectives
ABSTRACT Li‐O2 batteries with an ultrahigh theoretical energy density of up to 3500 W·h/kg have drawn extensive attention as future energy storage technologies. However, large discharge/charge overpotentials (> 1 V) and unsatisfactory cycling performance are the main obstacles for practical appli...

| description | ABSTRACT Li‐O2 batteries with an ultrahigh theoretical energy density of up to 3500 W·h/kg have drawn extensive attention as future energy storage technologies. However, large discharge/charge overpotentials (> 1 V) and unsatisfactory cycling performance are the main obstacles for practical applications. Recently, integrating photocatalysis into Li‐O2 batteries has emerged as a promising method to mitigate overpotentials, but the rational design of photocathodes with excellent photoelectrochemical activity and stability remains challenging. This review focuses on recent research progress on the reaction mechanisms in photo‐assisted Li‐O2 batteries and the development of photocathodes. We present several strategies for tailoring catalytic materials from the perspectives of material selection and its catalytic performance optimization, aiming to provide a fundamental understanding and insights into the design of efficient photocathodes. The key challenges in constructing high‐performance photocathodes and potential strategies were also discussed, offering insights for the development and application of efficient photocathodes in photo‐assisted Li‐O2 batteries. |
