Abstract
Photoenhanced energy storage devices represent an emerging technology that integrates solar energy harvesting with efficient electrochemical storage. However, achieving seamless and efficient coupling between light utilization and high-performance charge storage within a single, integrated platform remains a major challenge. To address this challenge, this study develops laser-architected MXene-graphene composites that unify high-performance energy storage with photoenhancement. The reduced graphene oxide (rGO) and partially oxidize MXene composite induced by a laser redox process exhibits a hierarchical architecture with outstanding conductivity and surface area. This synergy enables supercapacitors with photoenhanced capacitance, delivering a 228% boost under illumination and record-breaking metrics in capacitance, 2591.75 farads per cubic centimeter (1455.21 farads gram), energy density, 0.518 watt-hours per cubic centimeter (0.345 watt-hours gram), and power density, 320.35 watts per cubic centimeter (180.31 watts gram). Our findings offer a promising route toward integrated, photoenhanced energy systems, advancing the vision of efficient and sustainable power technologies.
