A facile annealing strategy for achieving in situ controllable Cu2O nanoparticle decorated copper foil as a current collector for stable lithium metal anodes

Abstract

Lithiophilic Cu₂O nanoparticle decorated copper foil synthesized by a facile air annealing approach was employed as a lithium plating substrate. The Cu₂O layers can stabilize lithium nucleation and alleviate the growth of lithium dendrites, thus enhancing lithium plating and stripping performance. This simple strategy is easily scalable to achieve low-cost lithium metal anodes for commercial applications.
