Battery Materials

The Fraunhofer R&D Center Electromobility Bavaria offers materials and components development for today’s and tomorrow’s battery and energy storage systems. We focus on B2B services for lithium-ion (Li-ion) polymer and solid state battery technologies, modern lead-acid (LAB) and high-energy batteries.
 

Current work

Our current materials development aims at improved battery systems in terms of energy density, lifespan, safety, reliability, cycling stability, and production costs.

  • Innovative thin-film ceramic electrolytes for more flexibility and higher safety
  • New multifunctional hybrid polymers with higher chemical and thermal stability as well as high ionic conductivity serving as bulk electrolyte, binder and separator at the same time
  • High energy batteries with greater energy density and enhanced stability
  • Modified electrodes (thin-film or core-shell coating) with higher safety and cycling stability
  • Improved surface design for greater energy density and a longer lifespan
  • Tailored carbon additives to increase cycling stability, mass utilization and charge acceptance

     

Our competencies

  • Materials development and optimization – active materials, electrolytes, separators, additives
  • 20 years of experience and a top-notch equipment and infrastructure ensure the ideal matching of materials, components and design for optimum battery performance
  • Various wet-chemical coating technologies, starting with prototypes and small batches up to pilot plant scale
  • Layer thickness from 100 nm to 1 mm: spray and dip coating, slot-dye coating, tape casting, large and continuous roll-to-roll coating, doctor blade coating
  • Manufacturing of various cell types and sizes, powder or liquids, coin (CR2032) and  pouch cells (10 A, 140x230 mm²), high precision and reproducibility
