Defect-Mediated Oxygen Vacancy Engineering of CeO2 Unlocks Fast V2+/V3+ Kinetics for Vanadium Redox Flow Batteries

Vanadium redox flow batteries (VRFBs) are promising for large-scale energy storage, yet their high-power capability is hindered by sluggish V2+/V3+ redox kinetics at the negative electrode. While CeO2-decorated graphite felts are widely investigated, most lack precise oxygen vacancy tuning and atomic-level mechanisti...

P2-Type Cathodes Enabled by Oxygen Vacancies and Lattice Stabilization for High-Rate and Low-Temperature Performance

Layered transition-metal oxides are promising cathodes for sodium-ion batteries, but their performance is often complicated by oxygen vacancy (OV) formation and management. Intrinsic OVs, induced by external factors such as doping, play a pivotal role in regulating their physicochemical properties. However, precisely...
