    Due to climate change and the shrinking of oil, society is required to turn to sustainable and renewable energy development and utilization Therefore, people get renewable resources from solar energy and wind energy, and develop hybrid electric vehicles or electric vehicles with low carbon dioxide emissions However, the sun's energy at night is very small; wind energy can not meet people's daily needs; for the requirements of electric vehicles, people also expect to be able to run for several hours Therefore, the energy reserve system has begun to play an important role in people's lives Super capacitor is a new type of energy storage device between traditional capacitor and rechargeable battery Compared with traditional capacitor, super capacitor has higher specific capacity and energy density; compared with secondary battery, it has the characteristics of high power density, short charge and discharge time, good cycle performance, long service life and easy maintenance The dual function of the secondary battery, its power density is much higher than that of the ordinary battery, and its energy density is much higher than that of the traditional capacitor, which fills the gap between the two traditional technologies Super capacitor can be used in extremely bad environment such as extremely low temperature, and there is no environmental pollution Therefore, it has wide application prospects in aerospace, electric vehicles, wireless communication, consumer electronics and other fields Super capacitor is a new type of device which stores energy through the double layer interface between electrode and electrolyte Electrode materials and electrolyte, as the key factors affecting the performance and production cost of super capacitor, have been listed as the key research object in the research The decomposition voltage of electrolyte determines the large available voltage of super capacitor At present, as an important process in the production of super capacitor, electrolyte injection also determines the industrialization of super capacitor At present, there are two main ways to inject electrolyte in China: immersion and liquid injection However, due to the characteristics of electrolyte and core materials, electrolyte absorption is very slow in immersion and normal pressure injection Therefore, in recent years, many capacitor manufacturers gradually adopt the way of vacuum liquid injection, that is, before the liquid injection, vacuum the vacuum dried electric core to a certain extent, and after reaching a specific vacuum value, then carry out electrolyte liquid injection, so that it can be inhaled by negative pressure, greatly reducing the time of electrolyte absorption, and improving the production efficiency Since 2010, the technical team of Guangzhou feisheng has been focusing on the research and development of micro (low to micro level) fluid control system, focusing on ml level and micro level liquid injection Guangzhou feisheng took the lead in developing the 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 condition of vacuum degree - 95kpa The accuracy and CPK value are continuously accurate and stable after the field verification by customers Features and technical advantages of Guangzhou feisheng high vacuum liquid injection system: (1) single channel, double channel, and multi-channel options; (2) wide range of liquid injection, from μ l to ml; (3) rotary reciprocating piston pump, fast speed, high production efficiency; (4) touch screen control, simple and intuitive operation; (5) high vacuum liquid injection to - 95kpa; (6) high precision (up to 0.5%), high consistency and uniformity.
