Battery Post-Mortem Analysis
Analysis of battery electrode morphology, chemistry and electrolyte purity.
Intertek Allentown laboratory testing and characterization of a battery’s components, pre- and post-cycling, provides unique insight for advanced battery technology refinement. Establishing a baseline of raw materials, followed by post-mortem analysis of electrodes and electrolytes complement performance testing needed to validate new battery technology. Test methods are readily applied from design through manufacturing, from button and coin cell to a commercial scale battery product. Advanced analytical sciences provided by Intertek helps the customer understand effects on battery performance from electrode morphology, chemistry, electrolyte purity, and supports failure analysis investigations.
