Expediting Desolvation–Diffusion Kinetics by Self‐Cascade Catalysis for Durable Low‐Temperature Zinc Metal Batteries

open access: yesAngewandte Chemie, EarlyView.
A novel self‐cascade catalytic strategy is proposed by designing an atomically dispersed Bi on deficient LaMnO3.15 perovskite (SABi/U‐LMO), serving as a promoter on subsequently lateral deposition of Zn enabled by interfacial electric field regulation.

Copper Contact for Perovskite Solar Cells: Properties, Interfaces, and Scalable Integration

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Copper electrodes, as low‐cost, scalable contacts for perovskite solar cells, offer several advantages over precious metals such as Au and Ag, including performance, cost, deposition methods, and interfacial engineering. Copper (Cu) electrodes are increasingly considered practical, sustainable alternatives to noble‐metal contacts in perovskite solar ...

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

open access: yesAngewandte 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).

Asymmetric Electrolytes Govern Tetrahydroxozincate Dynamics for Stable Alkaline Zinc Batteries

open access: yesAngewandte Chemie, EarlyView.
This research tackles the limitations of alkaline zinc batteries by designing a series of metalloporphyrin molecules (Co‐4N, Co‐3N‐O, Co‐3N‐S) as electrolyte additives. The asymmetric structures, particularly Co‐3N‐O, accelerate the Zn(OH)42− decomposition via a modulated metal center and control Zn2+ transport through carboxyl groups.
