Graphical abstractNickel sulfide/N-doped graphene composite has been prepared through a simple one-step and in situ method using thiourea as the sulfur source and reducing agent. The nickel sulfide/N-doped graphene composite exhibits a relatively high reversible capacity and good cycling stability. The excellent electrochemical performance can be attributed to N-doped graphene, which improves the electronic conductivity of composite and suppresses the volume effect as elastic matrix. The one-dimensional structure of nickel sulfide facilitates the diffusion of lithium ions and electrons. The presence of N atoms can increase the lithium ions storage capacity.
