Regulating Uniform Zinc Deposition via Covalently Tethered Imidazolium Cations in Polyacrylamide Hydrogel Electrolytes for Stable Aqueous Zinc Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A positively charged polyionic liquid hydrogel electrolyte is developed for highly stable aqueous zinc‐ion batteries. Imidazolium cations anchored on the polymer framework create a dynamic electrostatic shield at the anode interface. This active layer effectively repels water molecules and guides uniform zinc deposition, thereby suppressing dendrite ...

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...

Design Principles of Electrocatalysts for Industrial‐Scale Water Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
This Review distills electrocatalyst design for industrial‐scale water electrolysis into integrated principles linking active‐site engineering, phase and lattice modulation, interfacial microenvironment regulation and mass‐transport control. By connecting catalyst families with HER/OER mechanisms and practical operating demands, it outlines pathways ...

Breaking the Polarity–Coordination Coupling in Electrolyte Design for High‐Voltage Lithium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Steric and electronic co‐regulation of 2,2,2‐trifluoro‐N, N‐dimethylethylamide (DMTFA) decouples high polarity from strong Li+ coordination, creating an anion‐mediated pseudo‐weakly solvating electrolyte. This design lowers Li+ desolvation barriers, enhances Li+ mobility, and builds B‐, F‐, and N‐rich inorganic interphases, enabling stable 3.0–4.6 V ...

A Fluorine‐Free, Low Ion Pair Electrolyte for Transition Metal‐Free and Halogen‐Free Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Fluorine‐containing electrolytes dominate modern rechargeable batteries, yet the fundamental design principles for fluorine‐free systems remain largely unexplored. We demonstrate that fluorine‐free electrolyte chemistry can simultaneously achieve long cycle life, fast charging, and stable interphase formation in sodium‐ion batteries.
