Electrical Energy Storage

Eco-friendly and Efficient Electrical Energy Storage

The storage of electrical energy is vital for many technical applications. This importance is highlighted by the variety of types of electrochemical storage systems (batteries). The efficiency and environmental friendliness of these batteries largely depend on the materials that are used. Maximization of the capacity, service life, and reliability of battery cells and battery modules requires the customized development of materials to meet production requirements.

Material and Process Development for New Energy Storage Systems – a Holistic Approach

Over the last 20 years the development of electrical energy storage systems has been dominated by the breakthrough of lithium ion technology. This technology has been effectively utilized for many applications – and still offers scope for further development.

Metal-air batteries potentially offer the next revolutionary product for the storage of electrical energy, and this has particular importance for the future commercial success of electromobility. These batteries have significantly higher theoretical energy densities compared to currently available commercially batteries. Primary cells have already been developed, but no material concepts for stable rechargeable cells have thus far been demonstrated.

The multidisciplinary Electrical Energy Storage project group is endeavoring to change this: Our broad experience in materials and process development is allowing Fraunhofer IFAM to explore new concepts for electrodes, cells, and battery stacks.
