Abstract Li–O 2 batteries (LOBs), which possess immense theoretical energy densities, have been widely recognized as a promising technology to revolutionize electrochemical storage. However, the severe overpotential induced by sluggish redox reaction kinetics significantly hinders their practical application. To address this challenge, photocathodes incorporated into LOBs, leveraging photovoltage compensate for charging voltages and achieve ultralow overpotential. Nevertheless, comprehensive review of photocathode in LOBs is still lacking. This timely aims introduce pivotal role photo‐assisted strategy provides an updated overview utilized LOBs. After demonstrating mechanisms reaction, research progress application various comprehensively reviewed. Special emphasis placed on critical correlation between material design key challenges including reduced potential/improved discharging potential, alleviated electrolyte decomposition, suppressed photogenerated carrier recombination, broadened spectral response ranges, decoupled mass transport electron transfer, modulated charge/discharge mechanisms. Finally, future directions development systems are The current important insight cathode state‐of‐the‐art favorable high‐performance
