Abstract

The propensity of metals to form irregular and non-planar electrodeposits at liquid/solid interfaces has emerged as a fundamental barrier to high-energy, rechargeable batteries that utilize metal anodes. We report an epitaxial mechanism to regulate nucleation, growth, and reversibility of metal anodes. The crystallographic, surface texturing, and electrochemical criteria for reversible epitaxial electrodeposition of metals are defined and their effectiveness demonstrated using Zn, a safe, low-cost and energy-dense battery anode material. Graphene, with low lattice mismatch for Zn, is shown to be effective in driving deposition of Zn with a locked crystallographic orientation relation. The resultant epitaxial Zn anodes achieve exceptional reversibility over thousands of cycles at moderate and high rates. Reversible electrochemical epitaxy of metals provides a general pathway towards energy-dense batteries with high reversibility.
