All-solid-state lithium-ion batteries (ASSLIBs) using sulfide electrolytes and high-capacity alloy-type anodes have attracted sizable interest due to their potential excellent safety high energy density. Encapsulating insulating red phosphorus (P) inside nanopores of a carbon matrix can adequately activate its electrochemical alloying reaction with lithium. Therefore, the porosity plays crucial role in performance resulting P/carbon composites. Here, we use zeolite-templated (ZTC) monodisperse micropores mesoporous (CMK-3) uniform mesopores as model hosts P. Our results reveal that enable more effective pore utilization for P loading, P@ZTC material achieve record-high content (65.0 wt %) confined within pores. When used an anode ASSLIBs, electrode delivers ultrahigh capacity 1823 mA h g–1 initial Coulombic efficiency 87.44%. After 400 deep discharge–charge cycles (running over 250 days) at 0.2 A g–1, still holds reversible 1260 (99.92% retention per cycle). Moreover, P@ZTC||LiNi0.8Co0.1Mn0.1O2 full cell deliver areal 3 cm–2 0.1C after 100 cycles.
