摘要：

All-solid-state flexible supercapacitors based on a carbon/MnO2 (UM) core-shell fiber structure were fabricated with high electrochemical performance such as high rate car ability 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 x 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.
