Durable Thin‐Film Porous Transport Electrodes for High Current Density PEM Water Electrolysis

Advanced Science, EarlyView.
Water electrolysis using porous transport electrodes with sputter‐deposited, ionomer‐free thin films of rutile IrO2 catalyst suppresses Ir dissolution by >10x over other forms of IrOx. The rutile IrO2 catalyst prepared by this readily scalable electrode synthesis method provides stable cell operation at 3 A cm−2 while using low Ir loading (0.4 mg Ir cm−

A Multifunctional Potent Lewis Acid for In Situ Formation of Poly‐Dioxolane Electrolytes Toward High‐Performance Quasi‐Solid State Lithium Metal Batteries

Advanced Science, EarlyView.
Conventional polymer electrolytes based on poly‐dioxolane (PDOL) suffer from low ion mobility and unstable interfaces. Here, AlCl3‐initiated in situ polymerized gel PDOL electrolytes (AGPE) form a facile Li+ conduction path and hybrid SEI layers, thus enabling high Li+ conductivity and uniform Li deposition.
