Abstract

The invention relates to a gel electrode, a full-gel-state ion thermoelectric supercapacitor and a preparation method of the full-gel-state ion thermoelectric supercapacitor. The gel electrode is a carbon nano tube CNTs/polyacrylamide PAM hybrid gel electrode. The capacitor comprises the gel electrode. The preparation method of the gel electrode comprises the following steps: mixing an acrylamidemonomer, an initiator and a cross-linking agent with a carbon nanotube dispersion liquid, stirring, and carrying out thermocuring, and is low in cost, simple in process and suitable for large-scale production. The obtained full-gel-state ion thermoelectric supercapacitor has good electrochemical stability, can be used as an energy storage device, can achieve conversion between heat energy and electric energy through the specific thermoelectric performance of the supercapacitor, and is expected to be applied to collection and reutilization of low-order waste heat as an energy conversion device.

Description

technical field [0001] The invention belongs to the field of electrodes and supercapacitors and their preparation, in particular to a gel electrode, a fully gelled ionic thermoelectric supercapacitor and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of flexible electronics and wearable electronic devices, low-order waste heat (such as the heat generated by electronic equipment for a long time) is difficult to collect and reuse as one of the common dissipative energy sources. and storage raised new issues. As common energy storage and energy conversion devices, traditional supercapacitors and thermoelectric generators can meet the needs of energy storage and conversion respectively, but with the rise of more and more self-powered devices, it is difficult for energy devices with single functions to simultaneously Realize the transformation and storage of energy. Therefore, it is of great significance to construct an e...
