Fiber-Based All-Solid-State Flexible Supercapacitors for Self-Powered Systems

All-solid-state flexible supercapacitors based on a carbon/MnO2 (C/M) core–shell fiber structure were fabricated with high electrochemical performance such as high rate capability with a scan rate up to 20 V s–1, high volume capacitance of 2.5 F cm–3, and an energy density of 2.2 × 10–4 Wh cm–3.

Zusammenfassung:All-solid-state flexible supercapacitors based on a carbon/MnO2 (C/M) core–shell fiber structure were fabricated with high electrochemical performance such as high rate capability with a scan rate up to 20 V s–1, high volume capacitance of 2.5 F cm–3, and an energy density of 2.2 × 10–4 Wh cm–3. By integrating with a triboelectric generator, supercapacitors could be charged and power commercial electronic devices, such as a liquid crystal display or a light-emitting-diode, demonstrating feasibility as an efficient storage component and self-powered micro/nanosystems.
