Single-site carbon layer-based flexible interdigitated micro-supercapacitor: custom miniaturization and surface functional engineering

Abstract

Here, we demonstrate a highly flexible and custom-made assembly of interdigitated micro-supercapacitors (AI-MSCs) based on single-site carbon-layered carbon microfiber (SSC-200|CMF) electrodes. The AI-MSCs deliver an energy density of ∼0.015 μW h cm⁻² and a power density of ∼11 μW cm⁻²via optimizing the electrochemical active functional groups on the carbon surface, enriching the surface chemistry with versatility.
