Battery performance, safety and lifetime are some of the major parameters needing improvement. It becomes more crucial as the era of electrification and battery technology is imminent. When developing a battery cell, it is important to have the right combination of characteristics required to achieve the end goal. This implies choosing the right chemistry, components and cell design. By harvesting experimental data, battery models can be parameterised and allows battery designs to quickly move into production with reduced cost and equipment.

The two major parameters are often identified as the thermodynamic and kinetic behaviours, which are both functions of temperature. When a battery generates heat while operating, it becomes apparent that an accurate model can only be obtained when true isothermal boundary conditions are achieved. Temperature control equipment for battery parameterisation such as climate chambers are based on air convection cooling. Unfortunately, with batteries becoming more energy dense every year, climate chambers show limitations.

In a collaborative work, we show the development of an instrument for fast and accurate temperature control based on conductive cooling. The Isothermal Control Platform (ICP) delivers temperature step changes ≥ 10 °C/min, temperature control of ±0.15 °C and 3.5 kW cooling capacity covering a wide temperature window (-30 °C to 60 °C). Studies are still ongoing to fully asses the impact the ICP will have on new parameterisation procedures.

A PDF copy and recording of the presentation will be sent to all registered delegates after the event.

Speaker: Etienne Brouillet, Applications Scientist
