Polymer current collectors could prevent battery fires

A team of researchers has proposed a new approach to fix lithium-ion batteries' fire problem. The answer may lie in temperature-sensitive current collectors.What happens when a nail is driven through a lithium-ion battery cell? Researchers who observed the process claim to have developed a polymer-based method which counters the related fire hazard inherent in lithium-ion batteries. Academics from the U.S.' National Renewable Energy Laboratory (NREL); NASA; University College London; the Faraday Institution, in Didcot, England; the National Physical Laboratory, in London; and the European Synchrotron, ...
