Self-charging super capacitor

Abstract

Disclosed is a self-charging super capacitor. The self-charging super capacitor comprises: at least one nanometer friction generator which is capable of converting mechanical energy into electric energy, wherein each nanometer friction generator is provided with two output electrodes which are used for outputting electrical signals; a charging circuit module which is connected to the output electrodes of the at least one nanometer friction generator and is used for adjusting and converting the electrical signals output by the nanometer friction generator; and a super capacitor which is connected to the charging circuit module and is used for receiving the electrical signals output by the charging circuit module and storing same. In the self-charging super capacitor provided in the present invention, a nanometer friction generator acts as a charging power source, and the self-charging of the super capacitor is achieved by converting mechanical energy into electric energy through the nanometer friction generator and outputting electrical signals to the super capacitor for storage after adjusting and converting same through a charging circuit module.

Description

technical field [0001] The invention relates to the field of nanotechnology, more specifically, to a self-charging supercapacitor. Background technique [0002] Supercapacitors, also known as electrochemical capacitors, are an electrochemical energy storage device between traditional capacitors and batteries. Compared with traditional capacitors, supercapacitors have higher electrostatic capacity; compared with batteries, supercapacitors have higher power density and long cycle life. Combining the advantages of both, supercapacitors are energy storage devices with broad application prospects. [0003] Existing supercapacitors are mainly composed of electrodes, electrolytes and separators. The electrode includes two parts: electrode active material and collector. The function of the collector is to reduce the internal resistance of the electrode. It is required to have a large contact area with the electrode, a small contact resistance, strong corrosion resistance, stable ...

AI Technical Summary

Problems solved by technology

[0004] Although the supercapacitor has superior performance, its charging power source is single and cannot realize self-charging, so its use has certain limitations.

There are also some supercapacitors in the prior art, which can be prepared into flexible structures, but the preparation process is complicated, and it is not easy to be processed and produced on a large scale
