In the coming years, the demand for batteries will increase drastically - through electric mobility, portable electronic devices or decentralised energy storage. Researchers at HZB are developing battery systems such as lithium-ion batteries, but are also researching new concepts that are not yet ready for application.
One example is metal-sulfur battery systems. The researchers want to increase power and energy density and increase the number of charging cycles. To do this, they must understand the relationships between the atomic and mesoscopic structure of the materials used and the efficiency of the lithium-sulfur system. On this basis, metal-sulfur batteries are to be further developed until they are ready for application.
