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].
However, the potential for battery integration technology has not been depleted. Increasing the size and capacity of the cells could promote the energy density of the battery system, such as Tesla 4680 cylindrical cells and BMW 120 Ah prismatic cells.
The limited resources and space in the laboratory restrict the research activity on the battery system. Therefore, more collaboration between academic researchers and battery manufacturers could help the development of battery systems. Recycling becomes an inevitable topic with the surging of LIB manufacturing capacity.
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.
