Battery cell characterisation

At our premises in Zorneding near Munich, we characterize individual battery cells and smaller modules with regard to safety and quality requirements.

Our services include:

Cell chemistry

  • Chemical analysis of electrolyte and electrodes
  • Element distribution images in SEM+EDX
  • Phase analysis by X-ray diffraction (XRD)
  • Characterization of layers and layer structures

Qualification of manufacturing processes and manufacturing quality

  • Non-destructive structural imaging by computed tomography
  • Safe delaboration for further investigation after discharge
  • Verification of electrode structure and contacting in micrographs
  • Metallographic examination of pack and module frames (e.g. welded and soldered joints)
  • Test of mechanical safety devices (e.g. overpressure valves)

Reliability and transport safety

  • Electrical malfunction (overcharge, deep discharge and short circuits
  • Mechanical damage (shock/vibration, crushing, drop test, foreign object penetration)
  • Thermal and climatic testing (altitude simulation, temperature change/shock
  • Provoked thermal events / thermal runaways
  • Electrical performance testing
  • Capacity and cycle stability / lifetime
  • Power / power density
  • Resistances (surface, contact, ...)

Testing of complete e-vehicle systems such as missuse and abuse tests of entire lithium-ion battery systems are offered at our premises in Goslar at the GWP BATTERY TESTING HOUSE.
