Transition metallic chalcogenides (TMCs) with excessive theoretical capability are thought to be promising anodes for sodium-ion batteries (SIBs) however encounter a number of challenges due to the advanced conversion course of, which results in quite a few facet reactions and the inevitable disintegration of lively supplies, thereby impeding sensible software. On this work, impressed by a three-dimensional (3D) construction design, a steady 3D decreased graphene oxide with heteroatom-sites coordinated carbon facilities (3DNSrGO) is fabricated, which options uniform and considerable nickel sulfide (NiS) particles throughout the empty areas, together with enough entry to the liquid electrolyte, thereby enabling extra environment friendly switch of sodium ions. Furthermore, the mixture of the polypropylene (PP) membrane and glass fiber (GF) separator successfully reduces sodium polysulfide shuttling, prevents sodium metallic corrosion, and resolves short-circuiting points. Benefiting from the three-dimensional porous construction and simultaneous optimization on the battery degree, the nickel sulfide anode demonstrates improved charge functionality (particular capability of 386 mAh/g at 10 A/g) and long-term cyclic stability over 2000 cycles. This research holds appreciable potential for addressing (1) the rising requirement for environment friendly and sustainable Na+ host supplies, and (2) a newfangled method that optimizes the long-term cyclic stability of SIBs by way of a greater cell configuration.
