All-solid-state batteries are disadvantaged by their poor physical solid-solid interfacial contact and low ionic conductivity, which restrict their performance and hinder their short-term commercial applicability. Based on the interfacial protection strategy, researchers at UT Austin introduced fluoroethylene carbonate (FEC) into the PDOL system (1,3-Dioxolane (DOL) that can be polymerized through catatonically ring-opening reactions at room temperature to obtain poly(1,3-dioxolane). After the introduction of FEC, the accumulation of reaction products was reduced at the Na metal anode side prior to DOL addition, forming a NaF-rich passivation layer and inhibiting further side reactions between DOL and the Na metal, and thus, effectively improving the overall performance of the batteries…read more.
