Chemical Testing EV Batteries

ATS’ A2LA-accredited Chemical Analysis Lab offers a variety of methods and services for chemical testing EV batteries. Our experts deploy powerful technology to precisely identify the material properties and reactions of each component for a thorough evaluation of the product’s makeup. Our work enables manufacturers to evaluate their product’s safety and quality before deciding on their next steps.
Gas Chromatography/Mass Spectrometer Analysis (GC-MS)
Gas Chromatography/Mass Spectrometer Analysis (GC/MS) identifies and quantifies chemicals in a sample. For example, when confirming a lithium-ion battery complies with lithium quantity regulations, ATS experts can use GC/MS to separate lithium from the other materials and measure its concentrations. Our powerful technology can detect organic compounds with trace levels as low as parts per trillion (ppt). For quick and accurate results, ATS uses an autosampler that holds up to 150 sample vials at a time.
Thermogravimetric Analysis (TGA)
Thermogravimetric Analysis (TGA) is a versatile procedure for evaluating a substance’s weight loss over time when subjected to extreme temperature changes, such as heating and cooling. ATS performs TGA to measure a battery’s properties and study its reactions in a temperature-controlled nitrogen or air environment. TGA provides information about a material’s:
  • Oxidative stability
  • Thermal stability
  • Exothermic and endothermic properties
  • Volatile content
  • Composition
Differential Scanning Calorimetry (DSC)
Differential Scanning Calorimetry (DSC) measures energy flow during thermal transitions as a function of temperature. DSC helps clients make informed decisions regarding material selection and quality control. Our experts use DSC to determine a material’s melting point, heat capacity, thermal conductivity, and the temperature it reaches during phase changes. DSC also provides a method of identifying and measuring the following:
  • Total energy released during crystallization
  • Total energy absorbed during melting
  • Glass transition temperature (Tg)
  • Oxidation energy
  • Oxidation Temperature
  • Thermal stability
  • Heat of fusion
X-Ray Diffraction (XRD)
The ATS metallurgy lab performs X-Ray Diffraction, commonly referred to as XRD or XRD analysis, without destroying the sample material. XRD exposes the sample to x-ray beams that scatter the material’s compounds in a unique diffraction pattern. We use this process to identify the material in the International Centre for Diffraction Data (ICDD) database.
ATS uses XRD to confirm a battery’s material composition and identify any impurities that may cause adverse reactions down the line. We can also apply this process to inform design and development improvement plans, reverse engineer a composite, and perform failure analysis.
XRD provides information about a material, including:
  • Composition
  • Crystal structure
  • Properties
  • Functionalities
  • Qualities
Standards
Our experts perform chemical testing on EV batteries in compliance with industry standards such as:
  • ASTM D934
  • ASTM E1131
  • ASTM E1641
  • ASTM E1868
  • ISO 11358
  • IEC 62660
