Dispersion

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

The process of preparing positive or negative electrode materials (including active materials, conductive agents, binders, etc.) by processes such as batching, stirring, high-speed dispersion, iron removal, and filtration, ultimately producing a slurry that meets the coating requirements.

The coating method involves the relative rotation between the coating roller and the back roller, allowing the coating slurry to be transferred from the coating roller to the substrate indirectly through the tension of the liquid, forming a coated liquid film on the substrate.

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

The process of heat and pressure shaping the electrode assembly by applying appropriate time, temperature, and pressure, controlling the thickness of the electrode assembly, and securing the shape of the loosely wound electrode assembly to prevent relative movement of the positive and negative electrode sheets.
