Materials Within A Battery Cell. In general, a battery cell is made up of an anode, cathode, separator and electrolyte which are packaged into an aluminium case.. The positive anode tends to be made up of graphite which is then coated in copper foil giving the distinctive reddish-brown color.. The negative cathode has sometimes used aluminium in the
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 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.
To complete the formation process, 3-5 cycles at 0.1 C at room temperature and 3-5 cycles at higher C-rate at higher temperature are required to control the thickness of the SEI layer. This takes several days and means the bottleneck in the battery formation process and the battery production itself.
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].
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.
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.
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.
