Tin sulfide (SnS

2

) anodes have garnered significant attention within emerging energy storage technologies. However

the application of SnS

2

is curtailed due to its inherent limitations

including poor cyclic stability and inevitable volumetric expansion upon cycling. This study reports the successful fabrication of an innovative SnS

2

-based composite

featuring an eggshell-like structured nitrogen-doped carbon coating

referred to as SnS

2

@NxC. This novel architecture

wherein SnS

2

acts as the core encapsulated by a nitrogen-doped carbon shell

characterized by a void space between the shell and core

is crucial in mitigating volumetric expansion. This configuration contributes to maintaining the structural integrity of the composite materials

even under the stresses of continuous cycling. Nitrogen within the carbon matrix enhances conductivity and promotes the formation of a more robust and stable solid electrolyte interphase (SEI) layer. Experimental investigations have substantiated the electrochemical superiority of the SnS
