Hydrophobic Deep Eutectic Solvent (DES) Design Enables Optimally Hydrated DES‐in‐Water Electrolytes for High‐Performance Bromine Redox‐Enhanced Energy Storage Systems

Advanced Functional Materials, EarlyView.
Faradaic charging with bromine redox chemistry shows promise for energy storage, yet its efficient use in aqueous electrolytes is hindered by water decomposition and polybromides' cross‐diffusion, leading to suboptimal cell performance. This study introduces a tetrabutylammonium bromide‐based hydrated deep eutectic electrolyte with optimized water ...

Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

Advanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

Advanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

Redox Electrolytes in Supercapacitors [PDF]

Journal of The Electrochemical Society, 2015
© The Author(s) 2015. Most methods for improving supercapacitor performance are based on developments of electrode materials to optimally exploit their storage mechanisms, namely electrical double layer capacitance and pseudocapacitance. In such cases, the electrolyte is supposed to be electrochemically as inert as possible so that a wide potential ...

Regulating the Interphase Strain in High‐Entropy Oxide Thin Films – An Approach to Attaining Giant Energy Storage Capability under Moderate Electric Fields

Advanced Functional Materials, EarlyView.
This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...
