5 Platforms

Material development and characterization in the network  

FestBatt consists of five joint projects - three material and two method platforms as well as a coordination project with the common goal of producing stable and high-quality solid electrolytes and their electrochemical characterization.

Material platform Oxides

Aims: Upscaling of the synthesis of high quality electrolyte materials (lithium oxides/phosphates); optimization of powder morphology, particle size and additives to improve compaction and ionic conductivity.
