%X <p><span>A lithium-metal composite is proposed, which includes a carbon-nitrogen modified stainless steel mesh (CNSSM) favoring homogeneous lithium-metal nucleation and growth of fresh and dense lithium deposits when employed as anode for lithium-metal batteries. This novel approach is able to overcome the usual drawbacks linked to the preexisting passivation layer at the surface of lithium. Instead, a favorable interphase with low resistivity is formed with the electrolyte, and the CNSSM modified lithium-metal composite (CNSSM-Li) results in low-voltage hysteresis (±24 mV) and allows stable and dendrite-free lithium electrodeposition. The performance of lithium-metal batteries demonstrates the outstanding capabilities of the novel CNSSM-Li electrode in promoting cell energy density and cycling stability. In addition, advanced X-ray nano-tomography is employed to characterize the composition and morphology changes of this electrode upon plating.</span></p>
