Process chain for the development of new battery cells

IWS Dresden focuses on research for electromobility as well as for stationary energy storage. With its know-how and the multitude of manufacturing technologies, Fraunhofer IWS contributes to the development of batteries at many points of the process chain and provides innovations. The Advanced Battery Technology Center was established to provide companies with solutions today and in the future. Here, we bring together expertise in advanced battery chemistry, innovations in electrode production and cell manufacturing technologies.

Thus, Fraunhofer IWS covers the entire process chain for the development of new battery cells with a focus on material, surface and laser technologies.

Process chain#

 

Material development

New carbon materials are being developed at the IWS. The range of services for applications in battery electrodes includes in particular:

  • carbon thin films
  • carbon nanomaterials
  • porous carbons and carbon/Si composites
 

Components and coatings

Low cost processes are being developed for high performance battery electrodes and separators. Focus topics are:

  • electrode development
  • functional films for cell components
  • high-energy anodes  (Li-metal- and Si-anodes)
 

Prototype cell manufacturing

IWS scientists develop cost-effective solutions along the process chain "manufacturing of battery cells":

  • Electrode packaging
  • Cell assembly process
  • Prototype cell design and evaluation
 

Battery recycling

Fraunhofer IWS participates in the development of ecologically and economically efficient processes for battery recycling. Part of our portfolio of services is:  

  • Detection of emissions during battery recycling
  • Development and testing of filter solutions for recycling processes
  • Resynthesis of recycled carbon material
  • Manufacturing of battery cells using secondary materials
