WebHydrogen atom abstraction from a series of homopolymers by cumyloxy radicals is examined under solvent-free conditions at temperatures that are relevant to radical-mediated polymer modifications. Abstraction efficiency data acquired for the thermolysis of dicumyl peroxide (DCP) within pure polymer samples establish an order of reactivity ... WebAdv. Sustainable Syst. 2024. Lithium–sulfur (Li/S) batteries are among the most promising next‐generation energy storage systems because of their high theoretical specific energy of ≈2600 Wh kg−1. However, conventional Li/S batteries require high amounts of redox‐inactive liquid electrolytes, which do not contribute to cell capacity.
