Taking lithium-ion batteries to new extremes

08.10.2018 | Tech Xplore | www.techxplore.com

Lithium-ion batteries (LIBs) perform best when the temperature range is just right—that is, neither too hot nor too cold. But this is a huge limiting factor when it comes to using LIBs in electric vehicles (EVs) in many locales where temperatures vary widely.

In a recent paper published in Nature Energy however, a group of UC Berkeley researchers report a novel invention that promises to effectively mitigate the effects of thermal extremes when used with LIBs. Their solution is “a fluid-free, passive thermal regulator that stabilizes battery temperature in both hot and cold extreme environments.”

Improved li-lon batteries

To achieve this effect, their passive thermal regulator design draws on two key nonlinear features from existing thermal regulator concepts. The first of these features is solid-state phase change, whereas the second feature is opening and closing of a thermal interface.
