H.E.L Presentation: Battery Technology Testing

Key benefits and principles of isothermal and adiabatic calorimetry

Presentation on how both isothermal and adiabatic calorimetry can help design better batteries, including:

  • Principles of adiabatic and isothermal calorimetry testing on batteries
  • What information the testing will provide
  • What does this information mean for safe & effective battery development

Webinar hosted by Dr. Golik as part of their December 2020 energy series.

Host: Joe Willmot, Application Leader and Software Product Manager
Following time as an analytical chemist for BP, Joe joined H.E.L Group, spending three years as a Project Manager, giving him deep insight into the H.E.L products. He is now utilizing this knowledge as Application Leader and Software Product Manager, helping our customers find the best solution for their application

Understanding Battery Development Testing

With the need for higher energy densities, quicker charging times, and longer lifetimes, safety is a crucial consideration in developing more powerful batteries.

High-energy batteries contain highly reactive and potentially hazardous chemicals. These batteries will operate under, and be subjected to, a range of conditions. Therefore, understanding battery thermal behavior is critical to controlling cell self-heating and mitigating thermal runaway risk. Self-heating can arise from normal usage, or as a consequence of being subjected to a stress condition. These stresses can be broadly categorized as mechanical, electrical, or thermal stresses.

Understanding battery thermal behavior is also a critical consideration in the development of higher performance cells. Here, the relationship of thermal behavior with electrical performance, and its characterization, is essential.

Isothermal calorimetry with batteries
    • What are the basic principles of isothermal calorimetry
    • What information do we gain from isothermal calorimetry, and why do I care?
    • What does this information mean and what can I do with it?

Adiabatic calorimetry with batteries
    • What are the basic principles of adiabatic calorimetry with batteries?
    • Why is it appropriate to gather this information for batteries?
    • Why do I care about this information?
