Achieving High‐Instantaneous Pulse Power in Contact‐Separation TENG via Series Capacitive Voltage Control Architecture

open access: yesAdvanced Science, EarlyView.
Conventional contact‐separation triboelectric nanogenerators generate high voltage but deliver limited power due to premature charge dissipation. Here, a capacitive charge reservoir architecture decouples charge accumulation from discharge triggering, enabling sequential voltage amplification via floating‐layer capacitive coupling.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

open access: yesAdvanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Biosynthesis of Spatially Differentiated Cellulose for Flexible All‐in‐one Supercapacitors

open access: yesAdvanced Science, EarlyView.
Spatially differentiated bacterial cellulose is grown by oxygen‐guided biosynthesis to form dense surface regions connected by an open fibrillar interlayer. This architecture supports electroactive material loading, ion transport, and mechanical stability in an all‐in‐one supercapacitor, showing how biological assembly can create device‐ready ...
