All-solid-state lithium-sulfur battery (ASSLSB) is one of the most promising next-generation energy storage devices while confronting great challenges for practical applications, in particular the sluggish reaction kinetics of the insulating active materials, less solid-solid contact, and insufficient electronic/ionic conduction networks within cathode layer. Herein, a two-dimensional (2D) ordered mesoporous carbon (OMC) framework is developed and serves as an advanced host for active material Li₂S and solid electrolyte Li₆PS₅Cl (LPSC), forming a mixed conductive nanocomposite with 5 orders and 12 orders of magnitude increase in ionic and electronic conductivities compared with Li₂S, respectively. The ordered mesoporous in OMC provide confined space for the intimate contact between nanosized Li₂S and LPSC, which are favorable for continuous lithium-ion transport and increasing Li₂S utilization. Benefiting from these merits, the ASSLSBs employing Li₂S/OMC/LPSC nanocomposite achieve high reversible capacity and excellent cyclic performance at both high current density and high cathode loading.

全固态锂硫电池（ASSLSB）是最有前途的下一代储能器件之一，但在实际应用中面临着巨大挑战，特别是绝缘活性材料的反应动力学缓慢、固-固接触少、阴极层内的电子/离子传导网络不足。在此，本文开发了一种二维（2D）有序介孔碳（OMC）框架，并作为活性材料Li ₂ S和固体电解质Li ₆ PS ₅ Cl（LPSC）的先进主体，形成了5级的混合导电纳米复合材料。与 Li _{2相比，离子和电子电导率增加了 12 个数量级}S，分别。_{OMC中的有序介孔为纳米Li 2} S和LPSC之间的紧密接触提供了有限的空间，有利于锂离子的连续传输和提高Li ₂ S的利用率。受益于这些优点，采用 Li ₂ S/OMC/LPSC 纳米复合材料的 ASSLSB 在高电流密度和高阴极负载下均实现了高可逆容量和优异的循环性能。
