Product Parameters

Stud welding

The process of connecting the tab to the terminal post through welding.
X-ray detection

Placing the core pack, electrode assembly, or battery cell on a fixed apparatus and using low-energy X-ray transmission to inspect the relative position and dimensions of the material being tested.
Cap welding

Connecting or fastening plates, substrates, stops, insulating sheets, etc., together by welding to form a cover.
Inserting can

The process of assembling the electrode group into the casing.
Beading

The process of machining grooves near the positive electrode of a cylindrical lithium-ion battery using a grooving device.Note: Sealing gaskets are installed in the grooves to ensure the battery's sealing.
Sealing

The process of fully sealing the battery cell by either applying adhesive and curing it with steel ball dispensing at the injection port or using high-energy lasers to melt the cover plate and the sealing gasket together.
Pouch forming

The process of stretching the aluminum-plastic film to form a punched pit structure using a die.
First sealing

The process of immediately sealing the gas bag edge of a pouch cell after injection to completely isolate the interior of the cell from the external environment.
Second sealing

The process of puncturing the gas pouch of a pouch cell after the formation process, extracting the gas generated inside the pouch during the formation process, and then sealing it.
Degassing

The process of venting the gas generated inside the cell during the formation process to evacuate it from the cell.
Leakage test

The process of detecting whether there is a leakage in the battery using a vacuum test method or a helium leak detection method.
Electrolyte injection

The process of controlling the amount and injection time of liquid electrolyte to inject it into the battery through the injection port. The main purpose is to create ion channels, ensuring that there are enough lithium ions for reversible cycling between the positive and negative electrode sheets during the charge and discharge process. The injection process can be divided into hard shell injection and soft pack injection.
