Engineered Interface and Spatial Arrangement of Inorganic Components for Dendrite‐Free Li Anodes in Carbonate‐Based Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
A solid‐state ion exchange strategy constructs dentrimental Li2CO3 into a high‐modulus, high‐surface‐energy interface to enable dendrite‐free deposition of Li metal anode in the harsh carbonate‐based electrolyte. Abstract The practical application of lithium metal batteries (LMBs) in carbonate‐based electrolytes is hindered by uncontrolled lithium (Li)

Cr3+‐Activated Tunable Near‐Infrared Mechanoluminescence Materials for Potential Water Pollutant Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
Four kinds of magnetite type NIR‐ML materials are synthesized by high‐temperature solid‐state reaction method. The continuous spectral tuning from a sharp R line (698 nm) to a broadband range (650–1000 nm) is realized based on composite engineering, concentration engineering, and lattice engineering strategies.

PbCrO4/Pb Hybrid with Surface Unsaturated Metal Sites for Efficient CO2‐to‐Formate Reduction

open access: yesAdvanced Functional Materials, EarlyView.
An in‐operando electrochemically synthesized Vo‐rich PbCrO4/Pb hybrid exposes abundant unsaturated metal sites on PbCrO4 surface, which facilitates CO2 activation and stability of *OCHO intermediates. Simultaneously, the bulk Pb nanorod significantly enhances the conductivity of electrode for fast charge transport. The Vo‐rich PbCrO4/Pb electrocatalyst

Dual‐Phased Molybdenum Carbides Confined in MOF‐Derived Carbon Nanoframes Enhance Capacitive Desalination

open access: yesAdvanced Functional Materials, EarlyView.
Dual‐phase MoC/Mo2C/CoNC nanoframes are synthesized via a MOF‐on‐MOF strategy, demonstrating a large salt adsorption capacity, a low energy consumption, and an excellent cycling stability. In situ/ex situ characterizations and DFT calculations reveal that the MoC/Mo2C dual phase transition facilitates Na+ adsorption/desorption, while interface‐induced ...

Hydrogen‐Bond‐Rich Supramolecular Multiblock Copolymers Facilitate Rapid Zn2+ Migration in Quasi‐Solid‐State Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...
