On 13 May 2026, partners from IFP Energies nouvelles (IFPEN) contributed to the Convergence Science webinar on “Lithium-Ion Battery Thermal Runaway: Simulation and Experiment“, highlighting BATSS as a key example.
Advancing Understanding of Battery Thermal Runaway
The session focused on advanced experimental and numerical investigations into thermal runaway, crucial in lithium-ion battery safety. During the webinar, IFPEN presented the experimental framework developed to characterise thermal runaway. This included detailed analysis of vent gas emissions, covering aspects such as gas composition and release dynamics, as well as key parameters defining cell runaway behaviour, including characteristic temperatures.
IFPEN outlined their approach, which uses dedicated experiment to validate, step-by-step, the simulation of the venting phenomena. These simulations were carried out using Convergent Science modelling tools, aiming to replicate and better understand the complex processes observed experimentally.
The results demonstrated the robustness of IFPEN’s methodology as a first step and that the integration of experimental data with advanced modelling is helping to establish a consistent and validated approach to studying thermal runaway. This aligns directly with the core objective of BATSS: to support the development of high-performance, safe, and sustainable battery systems through efficient and reliable processes.
