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
The production of lithium-ion battery cells primarily involves three main stages: electrode manufacturing, cell assembly, and cell finishing. Each stage comprises specific sub-processes to ensure the quality and functionality of the final product.
There are many steps involved in making a battery cell. It all starts with electrode manufacturing. In 2021, Fraunhofer FFB put its first systems into operation in the "FFB Workspace" at the Alexianer Werkstätten. The video gives you an insight into the work on site. How exactly is a battery built and how does it work?

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.

Cell assembly can be roughly divided into three process routes for the three cell types (cylindrical, prismatic, pouch). The only thing the three routes have in common is the start with the cut-to-size electrode coils and the sealed cell as the end product, since the process guidance and the required equipment technology differ greatly.

The manufacturing of lithium-ion batteries differentiates cell formats by their physical shape and construction. Cylindrical, prismatic, and pouch cells each come with their own production advantages and challenges. Cylindrical cells, recognized by their circular cross-section, are among the oldest and most reliable formats. They''re made by

In the formation process (which has already taken place for the pouch), the cell is charged for the first time, which virtually activates the battery cell. The charging and discharging of the battery cell must be carried out in a very controlled manner so that the SEI (Solid Electrolyte Interface) forms in a thin and homogeneous layer on the anode.
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.
It begins with the careful preparation of electrodes, constructing the cathode from a lithium compound and the anode from graphite. These components are meticulously coated onto metal foils to set the stage for the battery’s future performance. Next is the assembly of the battery cell.

In this article, we will walk you through the Li-ion cell production process, providing insights into the cell assembly and finishing steps and their purpose.
The charging and discharging of the battery cell must be carried out in a very controlled manner so that the SEI (Solid Electrolyte Interface) forms in a thin and homogeneous layer on the anode. The (formation)gas produced is discharged via the corresponding valve openings.
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.
