Three-dimensional flower-like NiO on Cu foam as a lithiophilic current collector for high-performance lithium metal batteries

Abstract

Lithiophilic NiO with large surface area was grown on 3D copper foam by hydrothermal and post-annealing method. Flower-like NiO provides abundant active sites, which facilitates uniform deposition of lithium and effectively inhibit the growth of lithium dendrites.
