Hollow Carbon and MXene Dual-Reinforced MoS₂ with Enlarged Interlayers for High-Rate and High-Capacity Sodium Storage Systems.

ABSTRACT: Sodium-ion batteries (SIBs) and sodium-ion capacitors (SICs) are promising candidates for cost-effective and large-scale energy storage devices. However, sluggish kinetics and low capacity of traditional anode materials inhibit their practical applications. Herein, a novel design featuring a layer-expanded MoS₂ is presented that dual-reinforced by hollow N, P-codoped carbon as the inner supporter and surface groups abundant MXene as the outer supporter, resulting in a cross-linked robust composite (NPC@MoS₂/MXene). The hollow N, P-codoped carbon effectively prevents agglomeration of MoS₂ layers and facilitates shorter distances between the electrolyte and electrode. The conductive MXene outer surface envelops the NPC@MoS₂ units inside, creating i
