Abstract

The invention discloses a novel wearable supercapacitor fabric and a preparation method thereof, belonging to the technical field of energy storage. In this invention, a strip-shaped all-solid-state supercapacitor is first prepared by using a flexible film as an electrode material, and then a supercapacitor fabric composed of a plurality of strip-shaped capacitor units combined in a certain way is obtained by weaving. The outstanding feature of this fabric is that the electrodes of different capacitor units are connected to each other at the intersection, so that the capacitor units are connected in series or parallel, so that higher storage energy or higher operating voltage can be obtained for different capacitor units. Occasion wear. The invention skillfully utilizes the series-parallel connection theory of supercapacitors and the traditional cross weaving technology, avoids the introduction of insulating layers between capacitor units, and realizes the preparation of a new type of wearable supercapacitor fabric, which has broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of energy storage, and in particular relates to a novel wearable supercapacitor fabric and a preparation method thereof. Background technique

[0002] The development of modern electronics requires the use of flexible devices for energy conversion and storage, thus wearable smart textiles have been flourishing and have shown important application prospects in portable electronic devices. Supercapacitors have high energy density and outstanding power density, short charge and discharge time, and excellent cycle life. Flexible supercapacitors have been made into wearable power systems due to their flexible processing methods, tailoring and bending properties, and have been applied to various portable electronic devices.

[0003] The energy storage system currently used for weaving has a one-dimensional fiber energy storage system and a long strip energy storage system. For example, Gao Chao et al. (Nat. Comm...
