Abstract
Li-O2 batteries, which have high energy density, face some disadvantages in commercialization. To solve this, the potential of plasmonic materials, specifically gold nanoparticles can be used for enhancing the performance of rechargeable Li-O2 batteries. By incorporating these gold nanoparticles onto conventional cathodes, we demonstrate improved round-trip efficiency, capacity enhancement, and suppression of overpotential during cycling. The study also highlights the negligible catalytic effects of gold nanoparticles in dark conditions and rules out local heat effects induced by plasmonic interactions, providing valuable insights for the development of carbon-based cathodes with high-energy storage abilities.

Introduction
In recent years, the lithium-oxygen (Li-O2) batteries have gained attention due to their high theoretical energy density. However, they face challenges related to large overpotentials during the recharge (RC) step, mainly due to the slow decomposition of insulating Li2O2 at the cathode surface.
