Super capacitor injection method and vacuum injection solution

Guangzhou Ascend took the lead in developing a high-vacuum liquid injection system , and provided customers with a batch of vacuum liquid injection solutions.


At present, the main methods of electrolyte injection in China are immersion and injection. However, due to the characteristics of electrolyte and cell materials, the absorption of electrolyte is very slow during immersion injection and atmospheric pressure injection. Therefore, in recent years, many capacitor manufacturers have gradually adopted the method of vacuum injection, that is, vacuum-dried cells are vacuumed to a certain extent before the injection, and after a certain vacuum value is reached, the electrolyte is injected to make it pass the negative Pressure suction greatly reduces the time for electrolyte absorption and improves production efficiency.

Guangzhou Ascend's technical team has been focusing on the research and development of micro-fluid control systems (low to micro-upgrades) since 2010, focusing on micro-injection of milliliters and micro-upgrades. Guangzhou Ascend took the lead in developing a high-vacuum liquid injection system in 2016, and provided customers with a batch of vacuum liquid injection solutions (0 to -85kpa). Up to now, it can inject liquid under the vacuum degree of -95kpa. Field verification shows that the accuracy and cpk value continue to be accurate and stable.

Features and technical advantages of Vacuum Liquid Injection System

High precision (up to 0.5%), high consistency and uniformity;

The high vacuum liquid injection system has a wide range of liquid injection, from μl level to ml level;

The high vacuum liquid injection system adopts a rotary reciprocating plunger pump, which has high speed and high production efficiency;

Single-channel, dual-channel, and multi-channel options are available.

The high vacuum liquid injection system is controlled by a touch screen, and the operation is simple and intuitive

High vacuum injection as high as -95kpa
