Background  

Electrochemical Safety Research Institute (ESRI) of UL Research Institutes is dedicated to advancing safe energy storage through discovery-driven research. With renewable energy's growing importance, our scientists explore and address safety issues in batteries. Our work benefits the entire energy storage chain, promoting safety awareness and best practices. We understand that partnering with experts is vital for creating a safer and more sustainable world, where our collective efforts drive positive change. We engage in scientific research independently as well as in partnership with esteemed research institutions and leading experts. Our commitment to transparency drives us to disseminate this knowledge to scholars and industry leaders, setting benchmarks and offering guidance for the responsible advancement of products and emerging technologies.

Grant Purpose  

ESRI is interested in funding proposals that focus on monitoring designed to permit detection of possible thermal runaway of Ii-ion batteries. This may focus on gas sensing capability of small volumes of early release or large volumes that are released from Ii-ion batteries at various stages of thermal runaway. The preference is for dynamic gas sensing capability as the nature and volume of the gases can change with time as the battery continues to burn. An understanding of the scale of the event should be exhibited. This type of information will be very informative for prevention of full thermal runaway as well as for first responders and fire fighters to tackle large scale Ii-ion battery fires.

Applications for lithium-ion (Ii-ion) cells has increased exponentially in the past three decades with its use in battery systems ranging in size from 10s of kWh (typically used in electric vehicles) to MWh and GWh (typically used in stationary grid energy storage systems) becoming more common. However, the complexities of such a large battery system have challenged the safety of these installations. Lack of stringency at every stage of manufacturing as well as the inadvertent exposure to off-nominal electrical, mechanical, or thermal faults has caused these systems to experience catastrophic events.

Research has also indicated that lithium-ion cells are typically designed to vent the initial accumulation of gases and there may be a time gap between this initial venting and the final thermal runaway of the cells. It is possible to mitigate the thermal runaway if a good sensing of the gases emitted during venting is provided as mitigation strategies such as sudden cooling of the entire system can be initiated to prevent the catastrophic event from occurring. Dynamic gas sensing techniques can provide advance warning remotely to first responders and fire fighters on what can be expected with respect to trapped toxic and combustible gases when they have to deal with the large electric vehicle or energy storage systems fires.

Eligibility Information  

Who Should Submit Proposals:  
All proposals should be submitted by an accredited college, university, government, or non-government organization (including not-for-profit and for-profit institutions) with recognized legal status in their respective country.  

At ULRI, diversity, equity, and inclusion (DEI) are critical to who we are and what we represent as a leading safety science organization.
