Then the electrolyte will be filled and the battery cell will be sealed, followed by the forming and testing steps to finish cell manufacturing. In the battery cell manufacturing process, three steps require roughly equal shares of capital expenditures: 35 to 45 percent for electrode-manufacturing equipment, 25 to 35 percent for cell-assembly-and-handling equipment, and 30 to 35 percent for cell-finishing equipment (Exhibit 2). Electrode production benefits from faster drying times that increase yield rates and reduce capex for equipment. The production-related costs (excluding materials) can be reduced by 20% to 35% in each of the major steps of battery cell production: electrode production, cell assembly, and cell finishing. These thin films are then layered upon each other with a separator in between. Validate the feasibility of the innovative battery electrode manufacturing process by demonstrating implementation in the production, testing, and integration of items for DLA. The performance of lithium-ion batteries is determined by the architecture and properties of electrodes formed during manufacturing, particularly in the drying process when solvent is removed and the electrode structure is formed. Figure 1 introduces the current state-of-the-art battery manufacturing process, which includes three major parts: electrode preparation, cell assembly, and battery electrochemistry activation. Specific materials coated on the substrate function as the positive electrode (anode), negative electrode (cathode), and separator for isolating them, which combine to form the layered electrode (layered element). The Manufacturing processes can be divided into several stages like Oxide and grid production process, pasting and curing, assembly process, formation, filling, charge-discharge process, final assembly, inspection and dispatch. "In the future, we believe that battery manufacturers will not only differentiate on energy density, fast charge ability, or cost/kW, but also on the amount of CO 2 emitted per the amount of energy stored, which is a measure of how sustainable one's electrode manufacturing process is. Outcomes include establishing active material ingredients morphology and alignment, and developing an efficient electrode manufacturing process.

Coating both sides simultaneously effectively doubles . Mastery of the highly interlinked process chain in lithium-ion battery manufacturing is a challenge and often acquired on the basis of experience. This requires two separate passes through the same coating line, whereby a second coating station is installed after the drying oven. However, there are different ways to stacking process. "The conventional coating process uses a wet chemical method that applies what is known as slurry," explains Benjamin Schumm, group manager for Chemical Coating Technologies at IWS. This approach facilitates the interaction, integration, and fusion between the physical and cyber worlds of manufacturing. Conventional processes for manufacturing battery electrodes involve mostly toxic solvents and require a lot of space and energy. The cells are then arranged and connected to make a battery pack.
