AI Technical Summary

Technical Problem

Existing low-temperature lithium-ion capacitor electrolyte preparation devices suffer from several drawbacks during electrolyte filling, including reliance on manual operation, difficulty in quickly adapting to different tube specifications, insufficient injection uniformity and leak prevention safety, inadequate automation and ease of operation, and difficulty in meeting the requirements for high-efficiency, low-loss, and multi-specification compatibility.

Method used

A low-temperature lithium-ion capacitor electrolyte preparation device was designed, comprising an injection mechanism, a fixing mechanism, and a hydraulic device. The fully automated filling of the electrolyte is achieved through an automated injection mechanism, which is adaptable to tubes of different diameters. A central rod and a closed tube are set to enhance the isolation effect. Threaded connections and an acceleration disc are used to improve the injection uniformity and speed. Automatic tube alignment is achieved through air pressure balance.

Benefits of technology

The entire electrolyte filling process has been automated, which has improved the applicability and safety of the equipment, enhanced injection uniformity and production efficiency, reduced personnel training costs, ensured the uniformity and smooth flow of electrolyte, and avoided the risk of leakage.
