Facet/Interphase Dual Engineering of Zn Anodes via Silicotungstic Acid Etching for Highly Reversible Aqueous Zinc-Ion Batteries.
Rechargeable aqueous zinc ion batteries (AZIBs) are constrained by dendrite growth and water driven side reactions at the zinc anode, which erode reversibility and shorten cycle life. Here we show that a single silicotungstic acid (STA) etching step can simultaneously engineer the crystal orientation and interfacial ch...
