Process chain for the development of new battery cells

IWS Dresden scientists focus their research on electromobility and stationary energy storage systems. Thanks to its know-how and the large variety of manufacturing technologies, the IWS team can essentially contribute to battery development processes and innovations in many areas of the process chain. The Center for Battery Research at IWS has been established to be capable to support enterprises with solutions today and in the future.

IWS services the complete process chain for the development of new battery cells with a focus on material, surface and laser technologies.

Prozesskette

 

Material development

New carbon materials are being developed at the IWS. The range of services for applications in battery and supercap 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“, including:

  • electrode handling
  • cell assembly process
  • prototype cell manufacturing for new battery chemistries
