Powder metallurgical 3D nickel current collectors with plasma-induced Ni3N nanocoatings enabling long-life and dendrite-free lithium metal anode
文献摘要：
Building three-dimensional(3D)current collectors is a promising strategy to surmount the bottlenecks of lithium metal anodes(LMAs),but the regulation methodology of a 3D current collector has seldom been considered comprehensively concerning both skeleton architectures and surface coatings.Herein,a robust porous 3D nickel skeleton(NS)with lithiophilic Ni3N nanocoatings(Ni3N@NS)is synthesized via an integrative route of powder metallurgy/plasma-enhanced nitridation technics.The facile powder metallurgical method facilitates the adjustment of NS architectures toward sufficient electrolyte adsorp-tion and even current density distribution,while the followed plasma-enhanced chemical vapor deposi-tion(PECVD)method can induce compact Ni3N nanocoatings on NS,which reduces the Li nucleation overpotential,accelerates the Li-ion transfer,and facilitates a highly reversible oriented texture of Li deposition morphology owing to the dense and homogenous deposition of Li into the pores.The opti-mized Ni3N@NS current collector shows a high averaged Coulombic efficiency(CE)of 98.8％over 350 cycles,a prolonged lifespan of 1000 h(at 2 mA cm-2)in symmetrical cells,together with the significant performance in full cells.The ingenious methodology reported in this work can also be broadly applicable for the controllable production of other 3D skeletons with nitride nanocoatings for various applications.
