Battery technology continues to evolve and grow to enable devices that provide mobility, convenience, and innovation for consumers and larger solutions such as battery energy storage systems (BESS) for use in buildings. Though these technologies are paving the way for a more advanced future, manufacturers using lithium-ion batteries in their devices have a lot to consider to help every device remain as safe and effective as possible.

UL, as a leader in battery technology safety, remains aware of these technology changes and continues to develop industry standards that promote safer design practices to help global manufacturers innovate safely. At this year’s 36th annual International Battery Seminar, UL experts were available to answer questions, provide expertise, and present on three topics pertinent to the battery industry.

In “Advancing Battery Tech Innovations Through Safety,” Michael Sakamoto, UL Senior Business Development Manager, Consumer Technology, looked at UL’s role in the development of these important safety standards. While examining the risks associated with various devices and the standards available to address shifts in technology and demand, Sakamoto highlighted product specific standards and looked at the potentially unique demands of different markets.

The following day, Laurie Florence, Principal Engineer for Stationary & Motive Batteries and ESS, UL Energy & Power Technologies, shifted the focus from consumer products to BESS in “Understanding Regulatory Hurdles to Installing Battery Systems in Buildings.” After first reviewing codes and code updates that affect the BESS market, Florence walked attendees through the intersection of these codes and relevant safety standards before turning her attention to the safety updates that affect global manufacturers.

Finally, in the third presentation, “Safety of Aged Pouch Format Lithium-Ion Cells,” the findings from Phase I of UL’s collaborative study with Purdue University were presented. This study examines the aging and safety of lithium-ion cells of cylindrical format in metal cans that include internal protective features, and the results from both off-nominal tests, such as overcharge and external short, along with the destructive analysis of the fresh and aged cells were shared.

As the market grows and new developments take shape, UL will remain at the forefront of these changes, working with manufacturers and regulatory agencies to help keep safety a priority.
