High-performance electrochemical energy storage systems are of great importance for applications in electromobility and stationary energy storage. To achieve this, improving gravimetric and volumetric energy density, as well as reducing production costs, is crucial. Only an in-depth understanding of the processes involved in manufacturing lithium-ion batteries (LIBs) enables the production of improved and more cost-effective battery cells.

For this reason, the Battery Production Department focuses its research on the manufacturing of innovative battery cells. The core of this work is process development and the optimization of all processes within battery production. From mixing the electrode materials to the formation of the finished cells, all steps are carried out in-house on the iwb's research production line. Occupational safety is always a top priority here. Due to the industry-oriented research at the iwb, the highest safety standards are maintained along the entire process chain. The cell portfolio includes various cell types (coin, pouch, and hardcase cells) with capacities ranging from a few mAh to over 20 Ah. For this purpose, the iwb is equipped with industry-oriented plant technology, which can be flexibly adapted to a wide variety of requirements.

In addition to a wide range of materials for conventional LIBs, the department also works with solid-state batteries and the use of metallic lithium, as well as silicon-composite anodes for the production of next-generation LIBs.
