Traditional single-phase electrolytes, which are widely used in current state-of-the-art rechargeable batteries, have difficulties simultaneously fulfilling different chemical/electrochemical requirements of anodes and cathodes. Here, we demonstrate a new class of monolithic heterojunction quasi-solid-state electrolytes (MH-QEs) based on thermodynamically immiscible dual phases. As a proof-of-concept of the MH-QEs, their application to lithium–sulfur batteries is explored. Driven by combined effects of structural uniqueness and thermodynamic immiscibility, the electrode-customized MH-QEs provide exceptional electrochemical performance that lies far beyond those accessible with conventional battery electrolytes.

基于热力学不混溶双相的单块异质结准固态电池电解质†

传统的单相电解质广泛应用于当前的最新可充电电池中，很难同时满足阳极和阴极的不同化学/电化学要求。在这里，我们演示了基于热力学不混溶双相的一类新型单片异质结准固态电解质（MH-QE）。作为MH-QE的概念证明，已经探索了它们在锂硫电池中的应用。由结构独特性和热力学不混溶性共同作用的驱动，电极定制的MH-QE具有出色的电化学性能，远远超出了常规电池电解质所能提供的性能。
