Achieving Continuous Self-Powered Energy Conversion-Storage-Supply Integrated System Based on Carbon Felt.

ABSTRACT: Efficient harvesting and storage of dispersed irregular energy from the environment are crucial to the demand for the distributed devices of the Internet of Things (IoTs). Here, a carbon felt (CF)-based energy conversion-storage-supply integrated system (CECIS) that contains a CF-based solid-state supercapacitor (CSSC) and a CF-based triboelectric nanogenerator (C-TENG) is presented, which is capable of simultaneously energy storage and conversion. The simple treated CF not only delivers a maximal specific capacitance of 402.4 F g^-1 but also prominent supercapacitor characteristics with fast charge and slow discharge, enabling 38 LEDs successfully lightened for more than 900 s after a wireless charging time of only 2 s. With the original CF as the sensing layer, buffer layer, an
