Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.
Extruders provide excellent capabilities for solid state battery (SSB) development. An understanding of the rheological properties of an electrode slurry is necessary for a precise printing process to obtain batteries with a high capacity and a high number of charging cycles.
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format.
