Description

Technical Field

[0001] The utility model relates to the technical field of liquid flow battery assembly, in particular to a pressing device for liquid flow battery assembly. Background Art

[0002] Liquid flow battery is a new star of long-term and large-capacity energy storage. It can achieve cycle life, high safety and stability, and is green and environmentally friendly. It is suitable for the needs of the energy storage market. It realizes the storage and release of electrical energy through the mutual conversion of different electrolyte ions. Compared with traditional secondary batteries, its electrode reaction process does not have phase change, can be deeply charged and discharged, and can withstand large current charging and discharging. In the assembly process of liquid flow batteries, it is often necessary to use a special clamping device for clamping. However, in actual use, the existing clamping device usually directly places the battery to be assembled directly under the pressure plate. Due to the unrestricted structure, the liquid flow battery will slide during the downward pressing process, resulting in inaccurate clamping, which seriously affects the assembly quality of the liquid flow battery.
