An Electroanalytical Perspective on the Competitive Interplay between Zinc Deposition and Hydrogen Evolution in Aqueous Zinc Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
This perspective highlights recent electroanalytical measurement advances in aqueous zinc metal batteries (AZMBs). We describe tools that decouple competing pathways, such as zinc deposition, faradaic hydrogen evolution reaction (HER), and corrosion HER. We show how these insights can help enable the rational design of next generation AZMBs.

Beyond Silicon: Toward Sustainable, NIR‐II, and Conformable Organic Photodiodes

open access: yesAdvanced Energy Materials, EarlyView.
In this perspective, a strategic shift in organic photodetector (OPD) research is proposed: instead of the incremental advances in silicon's stronghold arena, the most impactful future for OPDs lies in addressing silicon's intrinsic limitations, i.e., detection in the longer wavelength range above silicon's coverage (>1100 nm, termed as near infrared ...

Hyper‐Areal‐Capacity Dry Electrodes (22.6 mAh cm−2) Enabled by Electron Beam‐Induced Functionalization of Fibrillated PTFE for High‐Energy‐Density Li‐ion Batteries (>400 Wh kg−1)

open access: yesAdvanced Energy Materials, EarlyView.
The electron beam (EB) irradiation on dry‐processed electrode enhances the electrolyte wettability by oxidizing the intrinsic super‐hydrophobic nature of polytetrafluoroethylene polymeric binders. Thus, enhancing interfacial Li+ transport, the integration of EB irradiation into dry electrodes provides a scalable, solvent‐free route to boost electrode ...

Trifluoracetic Acid‐Driven (002) Facet Engineering of Zn Metal Powder Anodes for High‐Performance Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A selective surface engineering strategy is presented for zinc metal powder (ZnMP) anodes in aqueous zinc‐ion batteries. Trifluoroacetic acid treatment enriches the exposure of (002) planes, forming a stepped hexagonal morphology that suppresses hydrogen evolution and dendrite growth.

Thermally Activated Dual‐Room‐Temperature Phosphorescence: Triplet Up‐Converted Anti‐Kasha in Dendrimers Enabled by Rigid Matrix Stabilization

open access: yesAggregate, EarlyView.
To address anti‐Kasha RTP's lacking design strategies and conventional rigid polymers’ failure to break Kasha's rule, this work synthesizes dTC‐BPSAF via acceptor dendronization. Carbazole dendrons regulate triplet hybridization to form near‐degenerate T1/T2.
