Wireless charging type super capacitor and manufacturing method thereof

Abstract

The present invention discloses a wireless charging super capacitor, which comprises a positive electrode, a negative electrode, a diaphragm disposed between the positive electrode and the negative electrode, an electrolyte, a packaging housing and a charging module. The charging module comprises a wireless receiver and a wireless transmitter. The wireless receiver is arranged at the preset positions of the positive electrode and the negative electrode. The preset positions are adapted for the wireless transmitter to send a radio signal to the wireless receiver. The wireless transmitter is controllably and electrically connected to an external power supply. The wireless charging is achieved through switching on / off the charging module. The invention also provides a manufacturing method of manufacturing the super capacitor, wherein a novel N / F co-doped carbon material is adopted to prepare the electrode of the super capacitor. The prepared super capacitor has the wireless charging function and is higher in power density and energy density and longer in cycle life.

AI Technical Summary

Problems solved by technology

At present, the most commonly used electrode material is carbon material, which has good electrical conductivity, high specific surface area, low density, controllable pore structure, low price, good chemical corrosion resistance, and power density can reach more than 10 times that of batteries, but the energy The density is less than one tenth of that of batteries, which seriously restricts the popularization and application of supercapacitors

[0004] In the prior art, the charging contact of the supercapacitor is exposed. However, due to factors such as deformation, elastic failure, rust or foreign matter, the contact will cause poor charging contact and affect the charging effect. At the same time, it is also easy to cause safety accidents. security risks
