Battery Modeling – Electrical and Thermal Models
Energy storage systems are widely used in many applications where the integration of such systems requires a proper design and sizing. To ensure a reliable design and operation of these systems for the above-mentioned applications, a system management including battery management and thermal management is indispensable. Such kind of system-level supervisors are based on efficient modeling approaches that include electro-thermal models. Electro-thermal model includes different models with different precision, where the higher model accuracy requires a higher computational effort and cost. In this webinar, different modeling methods based on the latest findings are explained and reviewed.
This webinar will focus on the following key topics:
• Battery thermal solutions: existing systems and trends
• Electrical behavior modeling
• Thermal behavior modeling
• 1D thermal model
• 3D thermal modelPresenter

Experimental Investigation of Cascading Failure in Lithium Ion Cell Arrays – Impact of Cathode Chemistry
In lithium ion arrays, thermal runaway may propagate from a failing cell to neighboring cells and grow into a large-scale fire in a phenomenon referred to as cascading failure. A new experimental setup was developed to investigate cascading failure using 12 cell arrays constructed from cells of 18650 form factor. Thermal runaway was initiated in one cell using an electric heater and observed to propagate through the array using temperature sensors. Cascading failure was studied in nitrogen or air environment to elucidate the impact of combustion. The cell temperature allowed calculation of row-to-row propagation speed in arrays of different cathode chemistries. The yields of oxygen, carbon monoxide, carbon dioxide, total hydrocarbons and hydrogen were measured; corresponding fire hazards were assessed.
This webinar will focus on the following key topics:
• Thermal runaway propagation
• Thermal runaway hazards
• Failure dynamics
• Flammability and toxicity
• Failure Mitigation and suppressionPresenter

Battery Design Optimization Using Cell Cooling Coefficient
Lithium-ion cells and battery packs are not designed to maximize the performance of thermal management systems. As a result, every cell in use is performing sub optimally, and is degrading needlessly fast. The root cause of the problem is the lack of information surrounding the thermal performance of lithium-ion cells. Cell Cooling Coefficients (CCCs) have been developed to quantify the cell thermal performance. They can immediately tell the user exactly how a cell will behave in a battery pack, vital information for the design of any thermal management system. They can also be used to inform redesign, both at the cell level and at the battery pack level.
This webinar will focus on the following key topics:
• Battery heat generation: why, and why is it complex
• Thermal management in battery packs
• The problems with battery design: energy density above all else
• Cell Cooling Coefficient as a universal metric
• Using the Cell Cooling Coefficient to evaluate battery design and propose beneficial redesignsPresenter
Alastair Hales – Research Associate, Imperial College LondonAlastair earned a PhD in Mechanical Engineering from the University of Bristol in 2016. Prior to joining Imperial College London in 2018, Alastair worked for SUEZ Advanced Solutions UK, designing equipment closely linked to his PhD topic, and as a Research Associate at Queen Mary University of London. Alastair’s existing work is focused around the thermal management and thermal effects of lithium-ion cells. Alastair led the work introducing the Cell Cooling Coefficient as a universal metric to quantify battery thermal performance. He is now building upon this research to develop capability for cell design optimization.

Approaches to Recovering Critical Materials From Spent Lithium-Ion Batteries
FREE Webinar – Li-Cycle is a proud sponsor of this event.
As the world transitions towards sustainability and low carbon emissions, lithium-ion batteries are being used across a broad spectrum of products and industries. The automotive industry, in particular, estimates 559 million of electric vehicles will be on the road by 2040. Consequently, lithium-ion battery waste is forecasted to hit over 11 million tonnes by 2030.
How can the world deal with this oncoming tsunami of lithium-ion batteries?
The audience will have the answer after this webinar as this presentation will walk through both global and future approaches to dealing with end-of-life batteries and explore the importance of recovering critical materials from lithium-ion batteries to meet future demand.
This webinar will focus on the following key topics:
• Global end-of-life lithium-ion battery market opportunity
• Recycling vs reuse
• Incumbent technologies for ‘recycling’ lithium-ion batteries
• New technologies and techniques for recycling lithium-ion batteries
• Comparative benefits of recycling technologiesPresenters
