Testing Laboratory: Battery Cell Testing & Post-Mortem Analysis

Are you looking for a testing laboratory for post-mortem battery (cell) testing? We open, analyze, and evaluate lithium-ion cells, sodium-ion (Na-ion) cells, zinc-based batteries, solid-state batteries, aluminum-ion cells, magnesium batteries, and lead-acid batteries—safely, reproducibly, and under controlled conditions. Our post-mortem analysis provides complete transparency into the internal condition of the cell—ideal for determining the cause of failure, assessing quality, and optimizing processes in development, manufacturing, and production testing.

Materialographic Sections

Imaging of electrodes, separators, layer structures, and contact areas to evaluate structure, integrity, and manufacturing quality.
 

Analysis of Cracks, Delaminations, and Porosity

Identification of structural defects—essential for determining the causes of capacity loss, gas leakage, or manufacturing defects.
 

Laser Welds & Contact Areas

Evaluation of joints, welds, and current paths to identify contact issues or manufacturing deviations.
 

Weld Analysis

Evaluation of the quality, integrity, and durability of welded joints in metals, electronic assemblies, and battery cells. By combining section preparation, optical microscopy, SEM analysis, and EDX element mapping, we identify bonding defects, porosity, cracks, weld inclusions, and material incompatibilities. For quality assurance, process optimization, and failure analysis. Analysis of soldered and welded joints in electronic assemblies; investigation of contact and current path issues in battery cells; identification of pores, bonding defects, inclusions, or hot cracks; comparison of welding parameters or manufacturing processes.
 

Supplementary Procedures

SEM/EDX analysis, macro/micro sections, LSM coating thickness measurement, damage analysis.
 

Result

  • Clear identification of the cause of the error
  • High-resolution image and findings documentation
  • Specific recommendations for action in the areas of development, manufacturing, or quality assurance

 

Processing time: a few days (depending on the cell type)
