Abstract

Lithium metal is considered to be a holy grail of the battery anode chemistry due to its large specific capacity. Nevertheless, the uncontrollable formation of lithium dendrites resulting from uneven lithium nucleation/growth and the associated safety risk and short cyclability severely impede the practical use of lithium metal anodes. Herein, we demonstrate a highly lithiophilic cobalt nitride nanobrush on a Ni foam (Co3N/NF) current collector as a stable three-dimensional (3D) framework to inhibit the dendrite formation of lithium. The 3D Co3N/NF nanobrush electrode could enable a low nucleation overpotential for homogeneous deposition of dendrite-free lithium. Compared to the CoO/NF counterpart and the bare Cu foil/Ni foam, the Co3N/NF nanobrush host is of great benefit for enhanced Coulombic efficiencies and longer lifespan at various current densities. The present work will offer a new insight for the exploration of the highly lithiophilic scaffold based on metal nitrides toward high-performance lithium metal anodes.
