IndustryNov 2, 2020
The recent recall of Hyundai Motor’s Kona electric vehicle is shining a spotlight on separators, one of the four key components of EV batteries along with cathodes, anodes and electrolytes. Separators are basically thin walls with tiny holes that divide cathodes from anodes. When batteries are charged and discharged, ions go back and forth between cathodes and anodes through these tiny holes. Separators prevent cathodes and anodes from reacting to each other and triggering short circui
