TL;DR: Graphene, with a low lattice mismatch for Zn, is shown to be effective in driving deposition of Zn with a locked crystallographic orientation relation, and the resultant epitaxial Zn anodes achieve exceptional reversibility over thousands of cycles at moderate and high rates.

TL;DR: Considering the large number of physical and chemical factors involved in achieving fine control of Li electrodeposition, it is believed that achievement of the remaining ∼0.5% in anode reversibility will require fresh approaches, perhaps borrowed from other fields.

TL;DR: In this paper, an oxygen-mediated metal-substrate bonding strategy was proposed to regulate metal deposition and demonstrate highly reversible Al and Zn anodes, and the reversibility is sustained over unusually long cycling times (>3,600 hours) and at areal capacities up to two orders of magnitude higher than previously reported values.

TL;DR: It is found that ion depletion at the mass transport limit may be overcome by spontaneous reorientation of Zn crystallites from orientations parallel to the electrode surface to dominantly homeotropic orientations, which appear to facilitate contact with cations outside the depletion layer.

TL;DR: The dendritic electrodeposition of lithium, leading to physical orphaning and chemical instability, is considered responsible for the poor reversibility and premature failure of electrochemical cel... as discussed by the authors.
