Ultra‐Stable Zinc Metal Anodes Enabled by Uniform Zn Deposition on A Preferential Crystal Plane

Periodic 3D hemispherical structured Cu foil with preferential exposure of the Cu (100) crystal plane are designed and obtained using a sequential photolithography-wet chemistry method. The 3D Cu foil lowers the Zn nucleation barriers, reduces the local current density and buffers the volume expansion during the cycling process, which induces homogeneous...

Micellar Solubilization for High‐Energy‐Density Aqueous Organic Redox Flow Batteries

Micellar solubilization enables the solubility enhancement of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) from 0.08 to 0.8 m in aqueous solution. Despite the encapsulation in micelles, micellar-solubilized TEMPO is electrochemically active and fully delivers reversible capacity in the flow cell test. Micellar solubilization also improves the chemical...

Suppressing Deformation of Silicon Anodes via Interfacial Synthesis for Fast‐Charging Lithium‐Ion Batteries

This work presents interfacial SiC bonding in a Si/Carbon composite, designed to effectively manage silicon deformation during repeated cycles. Unlike conventional synthesis methods that require high temperature (>1300 °C), SiC formation can be achieved at a relatively low temperature (900 °C) by tuning the graphitic plane orientation. This leads...

Redistributing the Electronic States of 2D‐Covalent Organic Frameworks for Electrochemical Energy Applications

The charge localization of 2D-COFs is effectively modulated to improve intrinsic conductivity and multiply redox-active sites to utilize the robust structures for industrial-scale electrochemical energy conversion and storage devices. The review discusses the versatility of structural modifications in 2D-COF by synthetic and post-synthetic strategies...

Stable All‐Solid‐State Na Batteries Enabled by In Situ Formed Na─B─H─F Electrolyte

A strategy for introducing F into hydride solid electrolytes is proposed. As a representative example, a Na─B─H─F electrolyte is prepared by the in situ reaction between Na2B12H12 and NaHF2, which has a unique microstructure (NaF nanoparticles embedded in amorphous Na2B12H11F matrix). This electrolyte exhibits superior electrode compatibilities, ascribed...
