Lithium-ion battery thermal runaway

Inside UL’s laboratories, lithium-ion batteries are pushed to the extreme. When it comes to evaluating the safety limits of mobile or portable devices – like hoverboards – engineers must understand how batteries will operate within the device, even under extreme conditions. In these videos, students can watch the abusive overcharge test and projectile test, which were filmed at the UL lab in Northbrook, Illinois. These videos supplement lessons on safety science and engineering, engineering and design, and energy. The videos can also be used to introduce UL Xplorlabs Module 1: Portable Electrical Power. See the News and Events page for articles about UL battery safety testing and safety standards created for lithium-ion batteries.
