Small-battery calorimetry for enhanced safety
Nature Energy, Published online: 12 May 2025; doi:10.1038/s41560-025-01776-yThe increasing energy density and size requirements for batteries demand better safety technologies, but size limits and high costs hinder effective testing. Now, accelerated rate calorimetry tests on small batteries with an optimal thermal runaway factor enable rapid screening and provide early-stage feedback for improving safety features.
