The vacuum standing box is a device that can be applied to the production of pouch cell lithium-ion batteries and cylindrical lithium-ion batteries. Its function is to complete the vacuum standing of the battery after liquid injection to promote the absorption of the electrolyte by the pole pieces; or It is used for vacuum standing defoaming and vacuum storage of various materials. The equipment adopts a split design, and the vacuum chamber can be placed in the glove box for use.

    The Battery Electrolyte Diffusion Chamber is a device that adsorbs the electrolyte to make it more fully integrated with the electrode sheet in a vacuum environment when injecting liquid into the pouch cell and the cylindrical battery. The whole machine is made of selected electrical components and materials, suitable for batteries of various sizes, easy to operate and high capacity. It is also an ideal multifunctional experimental equipment for the laboratory. This product uses the principle of vacuum standing to pump away the gas in the electrolyte. It flows smoothly along the battery core from top to bottom under the condition of its own gravity, so as to achieve better integration with the electrode core and play the role of the electrolyte.

    Working principle The device uses the upper cavity to press the bottom plate to form a closed cavity, and (time can be set) vacuumizes to a negative pressure state of -90KPa to remove the air in the cell, and the electrolyte is very strong under its own gravity. It flows smoothly from top to bottom along the battery core to achieve better integration with the electrode core and play the role of the electrolyte.

The main features of the vacuum standing box:

1. The vacuum remains stable. When maintained, the degree of vacuum does not decrease significantly.

2. Safe and reliable operation. Helps with emergencies (battery dumped, cavity pressure, etc.)

3. The product has a two-stage cycle operation function. Helps the electrolyte to fuse more fully.

4. When the work is completed and the cavity rises, it is very natural, and there will be no blasting sound and bounce.

5. The changes in the cavity can be observed during work through the viewing window in front of the execution structure.

6. Simple operation, beautiful appearance, small size and light weight.

7. The product is composed of two parts, the control electric box and the execution structure, which can be placed and operated separately.

Acey new energy provides the lab machine for cylindrical cell and pouch cell.
