Ru‐Doping‐Engineered Oxygen Vacancies in MoO3‐x Nanostructured Films With Ultrahigh Capacitance for Flexible Asymmetric Supercapacitors

Advanced Science, EarlyView.
Ru‐doping‐induced defect engineering enables freestanding Ru–MoO3‐x flexible films with enriched oxygen vacancies, modulated band structure, and enhanced charge transport. The optimized electrode delivers ultrahigh capacitance approaching the theoretical limit of MoO3, while assembled asymmetric supercapacitors exhibit high energy density, wide‐voltage

TiO6 as a Compensatory Structural Unit in Co‐Free, High‐Ni Layered Oxide for Durable Lithium‐Ion Batteries

Advanced Science, EarlyView.
Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

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 ...

Comprehensive Review of Synthesis, Structure, and Electrochemical Performance of LiFePO4

Advanced Science, EarlyView.
Olivine‐structured LiFePO4 (LFP) nanomaterials are the most effective cathode materials for lithium‐ion battery applications. Here, we report how precursor chemistry, synthesis routes, morphology control, carbon engineering, and doping strategies govern phase formation, charge transport, and electrochemical behaviour of LFP cathodes.

Architecting Phase‐Selective Interlayers for Stable SiOx Lithium Storage via Dual‐Function Design

Advanced Science, EarlyView.
Silicon anodes offer high capacity but suffer severe volume expansion. Silicon monoxide (SiO) buffers expansion, yet uncontrolled lithiation irreversibly consumes lithium as Li2O and oxygen‐rich silicates. Here, we design a layered SiOx featuring a phase‐selective conductive interfacial interlayer (PSCII), i.e., a Li4SiO4‐rich, ion‐accessible ...
