Ultra‐Low‐Cost Hydrophobic Organic Coating for Highly Reversible Zinc Anodes

Angewandte Chemie, EarlyView.
A nanoscale hydrophobic 1,3‐Di(o‐tolyl)thiourea (DTH) layer (<14 nm) was deposited on zinc anodes for durable aqueous Zn‐ion batteries, costing merely 1.43×10−7 USD·Ah−1. By suppressing side reactions and dendrites, it achieved 2500‐cycle coin cells and a 143 Wh·kg−1 pouch cell (1200 cycles) with a record‐low additive cost (7.02×10−7 USD).
