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.
