Sputtered thin film deposited laser induced graphene based novel micro-supercapacitor device for energy storage application.

ABSTRACT: Pioneering flexible micro-supercapacitors, designed for exceptional energy and power density, transcend conventional storage limitations. Interdigitated electrodes (IDEs) based on laser-induced graphene (LIG), augmented with metal-oxide modifiers, harness synergies with layered graphene to achieve superior capacitance. This study presents a novel one-step process for sputtered plasma deposition of HfO₂, resulting in enhanced supercapacitance performance. Introducing LIG-HfO₂ micro-supercapacitor (MSC) devices with varied oxygen flow rates further boosts supercapacitance performance by introducing oxygen functional groups. FESEM investigations demonstrate uniform coating of HfO₂ on LIG fibers through sputtering. Specific capacitance measurements reveal 6.4 m
