Processing of Batteries

Development and upscaling of electrode and cell manufacturing processes


The Fraunhofer R&D Center for Electromobility (FZEB) has been working on the processing of batteries since more than 10 years and is specialized on the development and upscaling of electrode and cell manufacturing processes.

With our comprehensive knowledge and understanding of materials and expertise on the processing of electrode materials as well as electrolyte coating and lamination we offer customized process development (from lab to pilot scale) for various types of batteries and electrochromic cells. Our resaerch focuses on the manufacturing of single and multi-layer stacks in small scale for investigating and evaluating novel electrode materials and cell types, such as lithium-ion (LIB), sodium-ion (SIB), solid-state battery (SSB), and electrochromic cells.


We provide electrode and cell manufacturing services for customers from various industries, e.g., electrode and battery cell manufacturers, chemical and materials companies.
