Abstract Electrocatalysis is considered to be an effective method solve the sluggish kinetics of lithium–sulfur batteries. However, a single catalyst cannot simultaneously catalyze multi‐step sulfur reductions. And once surface covered by initially deposited solid products, subsequent catalytic activity will significantly deteriorate.

Abstract In the majority of rechargeable batteries including lithium‐ion batteries, polyvinylidene fluoride (PVdF) binders are most commonly used binder for both anode and cathode. However, using PVdF requires organic solvent N ‐methyl‐2‐pyrrolidone which is expensive, volatile, combustible, toxic, has poor recyclability. Therefore, switching to aqueous electrode processing routes with non‐toxic would provide a great leap forward towards realization ideally fully sustainable environmentally...
