The production of the lithium-ion battery cell consists of three main process steps: electrode manufacturing, cell assembly and cell finishing. Electrode production and cell finishing are largely independent of the cell type, while within cell assembly a distinction must be made between pouch cells, cylindrical cells and prismatic cells.

Further, studies focused on the cost perspective have explored the economic feasibility of flow battery production (Dmello et al., 2016; Ha and Gallagher, 2015; Viswanathan et al., 2014) In contrast, little to no assessment of the environmental impact due to flow battery production has been undertaken (L''Abbate et al., 2019; Weber et al., 2018).

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 production of lithium-ion (Li-ion) batteries is a complex process that involves several key steps, each crucial for ensuring the final battery''s quality and performance. In this article, we will walk you through the
The first stage in battery manufacturing is the fabrication of positive and negative electrodes. The main processes involved are: mixing, coating, calendering, slitting, electrode making (including die cutting and tab welding). The equipment used in this stage are: mixer, coating machine, roller press, slitting machine, electrode making machine.
The key measurable characteristics of this process (viscosity, density, solid content) will directly affect the quality of the battery and the uniformity of the electrode. In the mixing process, the formulation of raw materials, mixing steps, mixing time are all important parameters.
The final shape of the electrode including tabs for the electrodes are cut. At this point you will have electrodes that are exactly the correct shape for the final cell assembly. In a cylindrical cell the anode, cathode and separator are wound into a spiral.
④ Slitting and notching : The flattened electrodes are cut into required sizes to fit for the battery. They are slit vertically in the slitting process and cut horizontally to get a V-shaped notch as well as cathode and anode tabs in the notching process. STEP 2. Cell assembly – forming the battery shape (pouch/ cylindrical batteries)
Direct calendering and free-standing electrode production are the most promising technologies at present and have the highest potential for timely implementation in industry. The active material is homogenized and preconditioned in a mixing process. The active material is fed to a pair of rolls in the form of a powder or granules.
Each step will be analysed in more detail as we build the depth of knowledge. The cell manufacturing process requires 50 to 180kWh/kWh. Note: this number does not include the energy required to mine, refine or process the raw materials before they go into the cell manufacturing plant.
