Problems solved by technology

However, this structure is difficult to achieve large-scale production, because the traditional textile process is not suitable for this kind of fiber, and repeated friction and stretching will cause the active material layer on the surface of the fiber to fall off.

Abstract

The invention discloses a transparent flexible electrochemical device based on a planar comb-shaped electrode structure, and a preparation method thereof. The planar electrode includes an anode and an A electrode (that is, a cathode or a counter electrode) arranged on the same transparent flexible substrate. Each of the anode and the A electrode includes a collection electrode and comb-shaped electrodes arrayed in parallel on the collection electrode. The comb-shaped electrodes of the anode and the A electrode are arrayed alternatively. The teeth widths in the comb-shaped electrodes and distances between adjacent teeth in the comb-shaped electrodes which are arranged alternatively are all between 10 micrometers and 100 micrometers. The planar comb-shaped structure is widely applicable to the field of electrochemical devices and the field of transparent flexible electronic products.

Description

technical field [0001] The invention relates to a transparent and flexible electrochemical device based on a planar comb-shaped electrode structure and a preparation method thereof. Background technique [0002] With the development of new materials and new processes, various transparent and flexible electronic devices are emerging, including display panels, field effect transistors, light-emitting diodes and solar cells. Most of them are based on organic thin film substrates, which are beautiful, light, easy to manufacture and low in cost. Compared with traditional silicon-based devices, during their processing, the temperature is often controlled below 200 degrees, which consumes very little energy and can reduce carbon emissions and environmental pollution. In the foreseeable future, electronic products widely used by people today, including mobile phones, laptops and tablet computers, will be replaced by corresponding transparent and flexible electronic products. For t...
