Characterizing Battery Thermal Performance: TGA, DSC, and Thermal Conductivity Testing

With increased consumer demand for environmentally friendly, sustainable transportation options, the performance of electric vehicles is an increasing priority. Intense research is being devoted to increasing the energy density, storage capacity, and cycling speed of battery systems. However, increasing energy density, storage capacity, and cycling speed comes with a consequence: more and faster generation of waste heat.

This can pose a hazard in the case of battery systems prone to thermal runaway issues – famously including Li-ion batteries but also lead-acid batteries and nickel-cadmium batteries, among others. Thermal runaway has been the cause of famous accidents, such as the crash of UPS Airlines Flight 6, reports of plane fires on the 787 Dreamliners and recreational devices such as scooters and cell phones spontaneously catching fire, sometimes while in use. Managing and reducing risk of thermal runaway in these systems is therefore a key safety priority.

However, even when the consequences of poor thermal management are not disastrous, it does come at a cost: shorter lifespan, reduced cycling efficiency, and lower storage capacity are all common consequences of battery material aging, which can be accelerated by overheating and poor thermal management. It’s therefore key from both a safety perspective and from a performance perspective to deeply understand the thermophysical considerations of the battery cycling process and the thermal hazards involved. Gaining this understanding requires a multi-technique approach.

This webinar will delve into thermophysical concerns in battery design and thermal management and the instrumental techniques needed to get the whole-system understanding required to design a robust, high performance, and safe battery system. Thermogravimetric Analysis, differential scanning calorimetry, Calvet 3D calorimetry, and thermal conductivity techniques will be examined and highlighted.

This webinar will be of interest to engineers and scientists working with battery technologies.

This webinar will air on July 9, 2020 @ 1:00PM GMT-3.
