Efficient Confinement of Solid Capacity Booster Powder as Monolithic Structures for High Performance Redox Mediated Flow Batteries

Advanced Energy Materials, EarlyView.
Solid electroactive materials are confined in a single porous block (so‐called monolith) that occupies the entire external reservoirs of Redox‐Mediated Flow Batteries. The monolith configuration possesses intrinsic advantages such as improved electrolyte flow distribution, enhanced kinetics, and utilization rates, as well as geometry‐tuneable pressure ...

Dynamic Cycling of Ultrathin Li Metal Anode via Electrode–Electrolyte Interphase Comprising Lithiophilic Ag and Abundant LiF under Carbonate‐Based Electrolyte

Advanced Energy Materials, EarlyView.
The silver trifluoromethanesulfonate (AgTFMS) simultaneously forms metallic Ag and abundant LiF on the Li metal surface after dissolution in carbonate‐based electrolyte, whereas lithium trifluoromethanesulfonate (LiTFMS) only generates LiF‐rich solid‐electrolyte interphase (SEI).

An enduring puzzle: the width variations of the 2175 Angstrom extinction band [PDF]

arXiv, 2010
Graphene, a single infinite, planar, sheet of graphite, has the same dielectric resonances as bulk graphite, but solid state theory indicates that its features are about half as wide. Based on this theory, the dielectric functions of mono- and multi-layer graphenes are deduced and compared with those of terrestrial graphite.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Unraveling Electrode Surface Chemistry in Determining Interphase Stability and Deposition Homogeneity for Anode‐Free Potassium Metal Batteries

Angewandte Chemie, EarlyView.
We disclose the effect of the current collector's surface functionality on determining the reversibility of anode‐free potassium metal batteries. The current collector with a lower Fermi level suppresses the electrolyte decomposition and induces an inorganic‐rich thin SEI. Additionally, the current collector with potassiophilic species creates abundant
