Researchers from Renmin and Tsinghua Universities in China have developed a novel shape-memory current collector (SMCC) that they say can stop battery thermal runaway in an overheated battery. Their paper, Early Braking of Overwarmed Lithium-Ion Batteries by Shape-Memorized Current Collectors, is published in the ACS journal Nano Letters. Unlike traditional current collectors made of copper… Read more »
