The lithium-sulfur battery has higher energy storage capacity and lower cost than lithium ion. But there is a serious stumbling block. Polysulfides form in the cathode during battery cycling and pass through the membrane to contaminate the lithium metal anode. This results in a rapid decline in performance. JCESR researchers appear to have found a solution to the problem – the “polymer of intrinsic microporosity” (PIM).
