Assembly of Battery Cells. Once the electrodes are coated, they are assembled into battery cells along with separators and electrolytes. This assembly process requires precision and careful handling to avoid contamination and ensure uniformity. Steps in the Lithium-Ion Battery Cell Manufacturing Process Mixing of Active Materials
Now the MIT spinout 24M Technologies has simplified lithium-ion battery production with a new design that requires fewer materials and fewer steps to manufacture each cell. The company says the design, which it calls "SemiSolid" for its use of gooey electrodes, reduces production costs by up to 40 percent.
The battery electrode manufacturing process begins with mixing active materials. The resulting slurries are coated onto the foils and dried, and then comes the roll pressing. Also called the rolling process, this is a process where the electrode goes through two rolls and gets evenly flattened.
