Battery Japan 2019

Battery Japan is world's leading international exhibition for rechargeable battery.

Future battery concepts should combine a high level of safety with high energy density and quick-charging capabilities. Novel all-solid-state batteries are a promising approach to match these requirements. One benefit of using solid electrolytes instead of the more commonly used liquid electrolytes is that in case of damage leakage and combustion are prevented. A key requirement for solid-state batteries is the development of highly conductive, costefficient and producible solid electrolytes and compatible active materials.

Active materials and components for all-solid-state batteries

Fraunhofer IKTS works on both Li-ion batteries and their production engineering, as well as batteries that use ceramic sodium conductors. As you will be shown on the booth, these development issues encompass complete value-added chains, from raw materials to systems and from the laboratory scale to full-scale indus­trial production.

Therefore, IKTS develops and synthesizes active materials with optimized electrochemical properties and adapted particle morphology as well as electrolytes based on ion-conducting glasses and ceramic materials for lithium or sodium batteries. An extensive glovebox system allows the handling of suspensions and samples that are sensitive to water and air and can be processed further and incorporated in test cells.

Beside electrochemical characterization, Fraunhofer IKTS offers a wide range of analytical methods, such as REM, XRD, thermal analytics and microscopy. These methods are also used in post-mortem analyses of solid-state battery cells and electrolytes.
