With our pilot line for battery cell production, we are validating new materials, promising battery technologies, innovative production approaches and sensor technology. In addition to electrode production and cell finalization, our research focus is on cell assembly, which plays a key role in battery cell production.
Therefore, only the production flow of the tray is considered here. The cell finishing process is divided into soaking, formation, aging, and testing. In the soaking lines, the battery cell is stored for several hours at a higher temperature to wet the dry battery coil after electrolyte filling.
On the one hand, cell finishing accounts for 20% to 30 % of the entire battery production cost, and on the other hand it has great impact on the overall battery cell quality. The battery cell finishing process comes with many different routes and process alternatives depending on the format, size, and chemistry of the battery cell produced.
In the layout of battery cell manufacturing, the formation process is a cost and area intensive process step. Different process parameters significantly influence the machine utilization, the energy flow, and the output of the cell manufacturing. This usually leads to non-optimally sized and operated formation lines.
It includes a series of steps and technologies aimed at optimizing the battery cell’s performance, quality, and safety. The process is divided into three categories: pre-treatment, formation procedure, and quality testing. The order of the processes and the time required for each step can vary depending on the manufacturer and the cell format.
In addition to the materials used, the manufacturing processes, their precision and process atmospheric conditions have a significant influence on the performance of the battery cells, such as ageing, safety and energy density. In our pilot line for battery cell production, the materials pass through seven stations from start to finish.
Due to the long process times and expensive power electronics of the formation process, formation and aging take the greatest share of time and cost in battery cell finishing. Therefore, the industry is keen on shortening those process times to lower production costs.
