Flow batteries can be best understood as a hybrid of traditional static batteries and fuel cells. Although the basic electrochemical principles of a static and flow battery are similar, one of the main differences is that a pumping mechanism is employed in flow batteries to deliver the electroactive species dissolved in the electrolyte from an external storage tank to the …
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.
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.
The production of battery cells comprises a complex process chain from the powder to the cell. There are many interactions between the individual process steps. Changes to individual process steps therefore often lead to changes along the entire chain. This is all the more true the further up the chain the respective step is located.
In addition to electrode production and cell finalization, our research focus is on cell assembly, which plays a key role in battery cell production. This involves going through various processes to produce a finished battery cell from the individual materials (electrodes, separator, housing, current collector tabs and electrolyte).
The limited resources and space in the laboratory restrict the research activity on the battery system. Therefore, more collaboration between academic researchers and battery manufacturers could help the development of battery systems. Recycling becomes an inevitable topic with the surging of LIB manufacturing capacity.
New materials and battery technologies often require the development of new manufacturing methods and processes. To this end, we research and develop in the areas of: The processing scale depends on the materials used and the type of question.
