Battery Manufacturing Terminology
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 creating a homogeneous slurry, also known as mixing, by thoroughly blending positive or negative electrode active materials, conductive agents, binders, solvents, etc., in a specific time, temperature, and pressure environment. This is achieved by controlling parameters such as vacuum level, temperature, stirring speed, and feeding sequence to meet certain particle size and viscosity requirements.
The process of achieving ultrafine dispersion by using the centrifugal force generated by the high-speed operation of the dynamic and static blade assembly in a high-speed disperser to break up agglomerates and large particle clusters in the slurry.
The process of removing iron-containing fine particles and impurities from the slurry.
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 process of transferring the prepared slurry to the coating head.
The process of uniformly applying the fluid slurry onto the surface of the current collector using coating equipment, followed by drying to form a film and produce battery electrodes.
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 coating method involves squeezing the coating slurry liquid through a coating slot to form a coated liquid film on the substrate.
The coating method involves using rollers to form a liquid film on a continuously moving substrate or the object being coated.
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.
The process of shearing the electrode sheet to form the tabs according to the designed dimensions by controlling the engagement between the upper and lower die of the equipment.
The process of longitudinally slitting the incoming film into multiple sections and winding them into upper and lower single rolls with a specified width.
The process of applying termination tape on the surface of the core winding direction of the pouch cell.
The process of applying termination tape on the surface of the lithium-ion battery core along the winding axis direction of the battery core.
The process of winding matched positive electrode sheets, negative electrode sheets, separator, and tab materials into a core assembly (winding core) by controlling factors such as equipment speed, tension, dimensions, and alignment.
