Directional Regulation of Zinc Deposition Through Constructing Hierarchical Janus Carbon Matrix with Organic‐Decorated Multi‐Channels

open access: yesAdvanced Science, EarlyView.
A Janus carbon matrix is engineered by covalently anchoring organic sulfonic anions within tubular pores of hierarchical CMK‐5, serving as an interfacial layer for Zn metal anodes. This design establishes a charge gradient for Zn2+ diffusion, enabling the directional deposition of confined and uniform Zn inside the pores while suppressing parasitic ...

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).

Perfluorinated polymer for vanadium flow battery

open access: yesDesalination and Water Treatment, 2013
ABSTRACT The perfluorinated polymers (Nafion) that have different thickness were evaluated for vanadium flow battery at different current density. The charge/discharge capacities depend on the start voltage of charge/discharge at each cycle. The cell with low vanadium permeability and low area resistance may improve vanadium flow battery performance ...

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

open access: yesAdvanced Science, EarlyView.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

Decoding Gas Evolution Pathways and Interfacial Chemistry in Layered Oxide Cathodes for Safer Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.
