Abstract

The invention relates to a composite energy device with a fully textile structure and a manufacturing method thereof. The composite energy device with a fully textile structure includes a friction generator based on a three-dimensional spacer fabric, a supercapacitor based on a three-dimensional spacer fabric, and a supercapacitor based on a textile yarn. Conductive fibers. The preparation of the composite energy device with a fully textile structure of the present invention includes two parts. First, the preparation of the flexible friction generator is completed with the spacer fabric as the base, and then the preparation of the supercapacitor is completed with the same spacer fabric as the base, and finally the two are assembled to complete Fabrication of integrated composite energy devices. The invention uniformly uses the three-dimensional spacer fabric as a base to realize an integrated friction generator and a supercapacitor with a unified integrated structure, and provides a new design idea for wearable self-powered devices.

Description

technical field [0001] The invention belongs to the technical field of flexible electronic devices, and relates to a composite energy device with an all-textile structure and a manufacturing method thereof. Background technique [0002] Flexible electronics have broad application prospects in information, energy, medical, national defense and other fields, and are increasingly attracting people's attention. All flexible electronic devices require a power source. The traditional power source is a rigid structure. The non-flexible power source device makes the wearability of the whole system a great challenge. To realize the ideal wearable, it is necessary to develop flexible, lightweight, and portable energy conversion or storage devices. As we all know, textile materials are naturally flexible and wearable, and the construction of energy devices based on textile materials is one of the ideal strategies to make energy devices flexible. In the past few years, there have been...
