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

Diagnosing the Role of Mn Additives in Aqueous Zn/MnO2 Batteries
Advanced Energy Materials, EarlyView.Aqueous zinc‐ion batteries frequently employ manganese dioxide cathodes and prevent capacity fade with manganese electrolyte additives. Using operando X‐ray fluorescence spectroscopy to directly track Mn concentration during cycling, we show that the beneficial role of the Mn additive appears to be as an additional source of redox‐active material ...

Angewandte Chemie, EarlyView.Bullvalene is a fluxional molecule capable of adopting numerous conformations spontaneously; just like a Rubik's Cube. In this paper, we explore the incorporation of bullvalene into the backbone of a highly rigid conjugated polymer semiconductor and observe that the inherent fluxionality reduces average crystallite size.
