Battery calorimetry

The market for lithium-ion batteries is expanding rapidly. Driven by electromobility, energy storage and the use of mobile devices, companies throughout the world are investing billions in research and development of the latest battery technologies.

With this growing market in mind, researchers are seeking to improve the performance, reliability and, above all, the safety of these batteries. The tendency for lithium-ion batteries to overheat means that safety is the most important factor in development. Thermal analytical procedures offer insights into how battery materials respond to thermal stress.

Knowledge of heat volumes is hugely important for quality and safety control of batteries, and that goes for battery research as well. Calorimetric measurement of batteries is currently standard practice in industry and research alike.

To find out how much heat can be discharged from cells, you have to understand the underlying heat conduction properties of the cell design. gSKINgt sensors assist in the analysis of these thermo-physical properties and support quality checks and product tests of batteries.
