LUNCHTIME WEBINAR - 17th MARCH 2021

We are pleased to confirm our next FABIG Lunchtime Webinar which will cover 'Risk management of Electrochemical Energy Storage Systems' and will be presented by Benjamin Truchot from INERIS on Wednesday 17th March 2021 from 13.00 GMT.

For additional information and registration, please go to the Events section of the website.

Abstract:

In the last decades, Electrochemical Energy Storage Systems have been used more and more for all types of applications, from the smallest batteries used in phones to large energy containers. Risks should be considered carefully when dealing with energy storage, as safety systems can depend on electricity supply for instance. Among available technical solutions, Li-Ion batteries (LIBs) are the most developed nowadays, although the term ‘LIBs’ actually encompasses a wide variety of systems of different chemistry, geometry, etc.

This presentation will provide an overview of LIBs and will describe some recent accidents to illustrate the different phenomena that occur during the thermal runaway of a LIB. Large-scale storage fires (Korea, Arizona, Belgium, etc.) will be presented together with some accidents which occurred on smaller systems. Knowledge gained from more than 10 years of abuse testing of LIBs and studies (including numerous research projects) will then be presented so as to raise awareness of the differences between battery designs in terms of reactivity e.g. a pouch does not react like a cylindrical cell and an LFP chemistry is not as reactive as an NMC one. Such aspects are crucial when designing an energy storage system.

Finally, current work on LIB thermal runaway modelling will be presented. This will focus on the required technical breakthrough to develop a relevant and reliable model to predict cell behaviour and thermal runaway propagation from cell to cell. Such a model should consider both inside cell chemistry together with large-scale combustion of electrolyte and solid conduction. While each piece of the model exists, putting all those pieces together to develop a reliable predictive model for all LIB characteristics is a real challenge. Such a model is however required to improve LIB safety and make the future possible.

FABIG WEBINAR SERIES

We will continue to organise lunchtime webinars every two weeks whilst working life remains disrupted by measures to combat the COVID-19 epidemic. Such measures either prohibit or make inadvisable large meetings such as our Technical Meetings.

We are looking for presentations covering topics relevant to the following themes:

  • Fire and Explosion Hazards from Low Carbon Energy Sources (we are also looking for presentations covering related incidents);
  • Robust Principles for Safe Design against Fires & Explosions based on Experience.

Please do not hesitate to contact us at fabig@steel-sci.com if you or one of your colleagues would like to give a relevant presentation.

Take care and stay safe,

The FABIG Team
