Valve solutions for mixing electrode slurries

The first step in the manufacture of lithium-ion battery cells is to mix the electrode slurries, which are then applied to the electrode foils (anode/cathode) as a layer in the next step. The slurry comprises a mixture of active materials, solvents, binders and additives. When mixing slurry, it is particularly important to feed in the different components in precisely the correct quantities. GEMÜ has the appropriate valves, measurement and control systems to ensure the process reliability of this manufacturing step. Find out more about the slurry mixing process and how GEMÜ supports you with expert solutions in this application flyer.
