Roll coating

The process, conducted at a temperature below the crystallization temperature (usually at room temperature), involves controlling the equipment's nip clearance, roll pressure speed, pressure, tension, and more to compress the loosely coated electrode sheet to the desired thickness and density. This process creates pores that allow the flow of lithium ions, while also increasing the energy density of the battery.

Components or batteries are successively placed into the assembly fixture, and through tightening bolts or gradually applying pressure, the batteries and components are assembled together to form the initial framework of the module.

The process of inputting positive or negative electrode materials (including active substances, conductive agents, etc.) into a mixing device through a metering system according to the preset ratio.

The process of removing moisture from the bare cell by controlling the equipment's heating rate, temperature, vacuum level, and duration to ensure that the water content in the cell meets the design requirements.

The process of applying termination tape on the surface of the core winding direction of the pouch cell.

The process of deactivating certain active components within the positive and negative electrode active materials through specific methods to enhance the overall stability of the battery's performance.
