Towards durable practical lithium–metal batteries: advancing the feasibility of poly-DOL-based quasi-solid-state electrolytes <i>via</i> a novel nitrate-based additive

Abstract

TEGDN-QSSE could form a N-rich SEI on the surface of a Li metal anode, protecting it from parasitic reactions and preventing Li dendrites. A pouch-type Li–S cell with TEGDN-QSSE could stably cycle 50 times.
