Description

technical field

[0001] The invention relates to the technical field of electrochemistry, in particular to a polymer electrolyte containing zwitterionic groups and redox groups and a preparation method thereof. Background technique

[0002] A supercapacitor is an energy storage device between traditional capacitors and batteries. It has the advantages of fast charging and discharging, high power density, long cycle life, etc. It can be used as an energy storage device in electric tools, hybrid vehicles, large pulse equipment and starting devices that have high requirements for power density. Electrolyte is an important part of supercapacitors and has a great influence on the overall performance of the device.

[0003] Liquid electrolytes have played an important role in electrochemical energy storage in recent decades. The liquid electrolyte has high ionic conductivity and makes good contact with the electrodes. However, the use of liquid electrolyte has the risk of leakag...
