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).

Untapped Potential: The Need and Opportunity for High-Voltage Aqueous Redox Flow Batteries
Prior studies of the techno-economic design space for aqueous redox flow batteries (AqRFBs) have almost exclusively focused on cell potentials ≤1.5 V, due, at least in part, to the belief that battery operation at higher cell potentials in not feasible due to electrolyte decomposition. However, … Read More
