Battery Japan 2020
The next generation of energy storage: Fraunhofer IKTS combines its unique competencies and shows advanced materials and components for all-solid-state batteries. Additionally, test procedures developed at the institute ensure compliance with the highest quality standards. Thus, partners benefit from an efficient, customized automated production from starting materials to storage systems.

Battery Japan is world's leading international exhibition for rechargeable battery.
Active materials and components for all-solid-state batteries
Fraunhofer IKTS works on Li-ion batteries and their production engineering. As you will be shown on the booth, these development issues encompass complete value-added chains, from raw materials to systems and test procedures, 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 batteries to achieve increased performance and ensure greater safety.
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.
Increased efficiency in the production of battery films through an inline inspection system
In order to increase the efficiency of the battery manufacturing process, i.e. to reduce reject rates and thus increase economic efficiency, Fraunhofer IKTS has developed an inline testing system that performs non-destructive testing during electrode manufacture for battery cells and detects defects or changes in the material composition as early as possible.
On a twin-screw extruder for battery electrode production, a multisensory mouthpiece was integrated between the extruder outlet and the coating die. Both the eddy current and ultrasonic methods are used to monitor battery electrodes. The combination of both measuring methods allows the acquisition of a wide range of material parameters.
