Boosting Charge Storage in Ferri/Ferrocyanide‐Based Alkaline Redox Flow Batteries
Angewandte Chemie, EarlyView.By modifying the solvation environment, cation engineering through Li+ substitution of traditional K+ or Na+ boosts the alkaline solubility of the ferri/ferrocyanide catholyte redox couple, providing a viable pathway to overcome the long‐standing challenge of energy density limitations for aqueous redox flow batteries (RBFs).

Parametrization and validation of a tool for the electrical design of tubular redox flow stacks
, 2023 All-vanadium redox flow batteries (VRFB) with a tubular cell geometry offer advantages over the common planar design: improved stability, reduced sealing lengths, cost-saving potentials through production of the components by (co-)extrusion and a more ...

Advanced Science, EarlyView.Autonomous laboratories can now synthesize materials faster than experts can interpret the resulting diffraction data. A probabilistic framework combines refinement‐fit metrics with large language model‐derived chemical reasoning to rank competing phase interpretations and flag those unsuitable for autonomous use.

Lignin as redox-targeted catalyst for the positive vanadium electrolyte
Electrochemistry Communications, 2022 Vanadium Redox Flow Batteries (VRFBs) are promising candidates for large- scale energy storage applications however, there are still some obstacles that need to be overcome such as their low energy density (25–30 Wh L−1 for a 1.8 M electrolyte), high ...

Advanced Science, EarlyView.An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Geometry‐Regulated Electrode‐Wide Nucleation Patterns in Aqueous Zinc Anodes
Advanced Science, EarlyView.Laser‐ablated 3D hole patterning enables geometry‐driven control of Zn deposition in aqueous batteries. The hole opening ratio (HOR) governs electrode‐wide nucleation patterns by regulating the spatial distribution of nucleation sites and the evolution of early‐stage Zn deposits.
