Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

Advanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Imidazolium Cation‐Stabilized Interfacial Chemistry for Durable Aqueous Cadmium‐Iodine Batteries

Angewandte Chemie, EarlyView.
An aqueous cadmium‐iodine (Cd//I2) battery is constructed through interfacial chemistry regulation. The cadmium anode effectively suppresses parasitic hydrogen evolution and enhances anode stability, while the incorporation of BMIM+ additives anchors polyiodide species, alleviating the polyiodide shuttle effect and reinforcing interfacial robustness ...
