Reveal Non‐Uniform Passivation on Lithium Metal Anode With Operando Spectroscopic Ellipsometry

open access: yesAdvanced Energy Materials, EarlyView.
In‐operando spectroscopic ellipsometry reveals how nucleation and crystallographic orientation govern the non‐uniform growth of native passivation films on lithium metal. Time‐resolved thickness mapping captures island formation and coalescence, while orientation‐dependent measurements show that the equilibrium film on Li(110) is approximately half as ...

Decoupling Quasi‐Solid‐State Sulfur Conversion Mechanisms in Weakly Solvating and Locally High Concentration Electrolytes

open access: yesAdvanced Energy Materials, EarlyView.
Weakly solvating CME–TTE and localized high‐concentration G2–TTE electrolytes redirect lithium–sulfur chemistry toward quasi‐solid‐state conversion through distinct coordination environments. Molecular dynamics and multimodal electrochemical and spectroscopic measurements show that G2–TTE couples multidentate solvent coordination, anion participation ...

Near‐Micron Single‐Crystalline Mn‐Rich Cathodes With Exceptional Cycling Stability

open access: yesAdvanced Energy Materials, EarlyView.
Earth‐abundant single‐crystalline Mn‐rich DRX material faces a synthetic limit in particle‐size reduction. Our automated TEM workflow reveals interparticle compositional heterogeneity in early‐stage DRX, which forms minor orthorhombic impurities during cooling and necessitates prolonged annealing.

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

open access: yesAngewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Locally Competitive Coordination Electrolyte for High‐Voltage Lithium‐Metal Batteries With Ni‐Rich Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
A locally competitive coordination electrolyte, formulated with a nitrile‐based solvent, dual borate salts, and ether co‐solvents and diluents, concurrently stabilizes Ni‐rich positive and Li‐metal negative electrodes. This design suppresses parasitic reactions while forming an inorganic‐rich SEI, enabling Li‐metal cells to stably cycle under stringent
