A Particle‐Level Dual‐Polymer Interphase for Coupled Interfacial and Contact Stabilization of Zinc Metal Powder Anodes in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A particle‐level dual‐polymer interphase of carboxymethyl cellulose (CMC) and poly(acrylic acid) (PAA) stabilizes zinc metal powder anodes by coupling CMC‐mediated water regulation with PAA‐derived Zn2+ affinity. This synergy suppresses hydrogen evolution, corrosion, and byproduct accumulation while preserving electrode‐level electrical contact ...

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...
