Thermal Analysis of Lithium-Ion Batteries
- Working principle and component parts of a lithium-ion battery
- Thermal analysis techniques used in battery investigations
- DSC examples: cathode, separator, binder, electrolyte
- TGA examples: cathode, anode, separator, binder
- TMA and DMA examples: separator membranes
- Choosing the best thermal analysis technique for your application
The increasing market of consumer electronics, smartphones, and electric vehicles is pushing battery research forwards to provide safer, lower-cost, and lightweight/high-capacity solutions. For example, investigating the safety risks associated with thermal runaway is particularly important for lithium-ion batteries in electric vehicles.
Thermal Analysis Techniques for Battery Analysis
Thermal analysis techniques play a vital role in the successful research and development of advanced battery technology. They are also ideal for carrying out routine quality control checks on finished products. The four main techniques of DSC, TGA, TMA, and DMA are particularly effective for investigating temperature-dependent effects such as glass transition, crystallization, melting behavior, purity, visco-elastic behavior, expansion, shrinkage, and decomposition. Evolved gas analysis combined with TGA can also provide important information regarding the products of decomposition.

Presenter: Angela Hammer (Dr. sc. nat. ETH)
Dr. Angela Hammer received a Ph.D. in Analytical Chemistry (development of immobilized components for the use in ion-selective electrodes based on polyurethane membranes) from the Institute of Organic Chemistry at the Swiss Federal Institute of Technology in Zürich, Switzerland. She then joined Sika Technology AG in Zurich, Switzerland, as an analytical chemist. In 2007, she joined METTLER TOLEDO and has worked there since as an application specialist for Thermal Analysis. In her present position, she uses, teaches, and supports DSC, TGA, TMA, and DMA instruments for the METTLER TOLEDO’s Materials Characterization Group located at the head office in Switzerland.
