The anode and cathode materials are mixed just prior to being delivered to the coating machine. This mixing process takes time to ensure the homogeneity of the slurry. Cathode: active material (eg NMC622), polymer binder (e.g. PVdF), solvent (e.g. NMP) and conductive additives (e.g. carbon) are batch mixed.

Abstract. The battery cell formation is one of the most critical process steps in lithium-ion battery (LIB) cell production, because it affects the key battery performance metrics, e.g. rate capability, lifetime and safety, is time-consuming and contributes significantly to energy consumption during cell production and overall cell cost. As LIBs usually exceed the electrochemical sability
In order to engineer a battery pack it is important to understand the fundamental building blocks, including the battery cell manufacturing process. This will allow you to understand some of the limitations of the cells and differences between batches of cells. Or at least understand where these may arise.
The battery manufacturing process is a complex sequence of steps transforming raw materials into functional, reliable energy storage units. This guide covers the entire process, from material selection to the final product’s assembly and testing.
6.1 Formation The formation process involves the battery’s initial charging and discharging cycles. This step helps form the solid electrolyte interphase (SEI) layer, which is crucial for battery stability and longevity. During formation, carefully monitor the battery’s electrochemical properties to meet the required specifications.
Figure 1 shows the lithium-ion battery manufacturing process that includes electrode preparation, assembly, and formation. The battery formation stage has two key functions; on one hand to create the solid electrolyte interphase (SEI) on the anode and cathode electrolyte interphase (CEI) [1-2].
Battery ingredients (cathode, anode, separator, electrolyte) are placed in the former and electrolytes are injected and gas is stored in the latter. The ingredients are piled up in the electrode pocket using “lamination and stacking” method and electrolyte is injected into the air pocket to reach even pores in the electrode pocket.
The manufacture of the lithium-ion battery cell comprises the three main process steps of electrode manufacturing, cell assembly and cell finishing. The electrode manufacturing and cell finishing process steps are largely independent of the cell type, while cell assembly distinguishes between pouch and cylindrical cells as well as prismatic cells.
In addition, the transferability of competencies from the production of lithium-ion battery cells is discussed. The publication “Battery Module and Pack Assembly Process” provides a comprehensive process overview for the production of battery modules and packs. The effects of different design variants on production are also explained.
