Risks associated with thermal runaway situations such as overheating and possible explosion, are especially important for the use of lithium ion batteries in EV applications. Innovative analytical solutions for thermal analysis can be used to test individual battery components, like anode/cathode electrode materials, separators, electrolytes and binders.
Thermal Analysis Techniques for Battery Analysis
Critical tools for the investigation of batteries' thermal stabilities, exothermic reactions and enthalpies include differential scanning calorimetry (DSC), thermogravimetry (TGA) and thermomechanical analysis (TMA). To acquire more information about degradation components from a single experiment, a METTLER TOLEDO TGA or TGA/DSC can be hyphenated to a suitable gas analysis system to perform, for example, Fourier transform infrared spectroscopy, mass spectroscopy, gas chromatography-mass spectroscopy or micro gas chromatography-mass spectroscopy (respectively FTIR spectroscopy, MS, GC/MS; Micro GC(/MS).
This application guide provides an overview of lithium ion battery technology and demonstrates how various thermal analysis techniques can be employed for a host of R&D and QC applications.
The following application examples are provided:
- Thermal stability of LiFePO4 cathode material in electrolyte
- Characterization of an electrolyte mixture
- Analysis of microporous separators by TGA and TMA
- Quality control of PVDF by TGA and DSC
- Conversion of graphene oxide into graphene (anode material)
