Sodium layered transition metal oxides have been considered as promising cathode materials for sodium ion batteries due to their large capacity and high operating voltage. However, mechanism investigations of chemical evolution failure at voltage are inadequate. As a representative cathode, Na2/3Ni1/3Mn2/3O2, the contribution 4.2 V plateau has long assigned redox Ni3+/Ni4+ couple, while same time it suffers irreversible loss during initial discharging process. In this work, we prove that is...

Abstract Exploring an active and cost-effective electrocatalyst alternative to carbon-supported platinum nanoparticles for alkaline hydrogen evolution reaction (HER) have remained elusive date. Here, we report a catalyst based on single atoms (SAs) doped into the hetero-interfaced Ru/RuO 2 support (referred as Pt-Ru/RuO ), which features low HER overpotential, excellent stability distinctly enhanced cost-based activity compared commercial Pt/C Ru/C in 1 M KOH. Advanced physico-chemical...

Abstract Prussian Blue Analogs (PBAs) have shown considerable prospects as the cathode materials for sodium‐ion batteries (SIBs) on account of their high theoretical capacity, low cost, and easy preparation. The practical capacity poor cycling stability PBAs, however, limit wide deployment. To address these issues, a new strategy is deployed through introducing Fe vacancies Cu‐dopant into PBAs frame structure, boosting specific improving stability. On one hand, introduction in PBA (PBA□Fe)...

Abstract Stable solid electrolytes are essential to high-safety and high-energy-density lithium batteries, especially for applications with high-voltage cathodes. In such conditions, may experience severe oxidation, decomposition, deactivation during charging at high voltages, leading inadequate cycling performance even cell failure. Here, we address the limitation of halide by introducing local lattice distortion confine distribution Cl − , which effectively curbs kinetics their oxidation....

Abstract Since the report of electrochemical activity LiFePO 4 from Goodenough's group in 1997, it has attracted considerable attention as cathode material choice for lithium‐ion batteries. It shows excellent performance such high‐rate capability, long cyclability, and improved safety. Furthermore, raw materials cost are lower abundant compared with conventional Li‐ion battery oxides compounds. The lithium extraction operates biphase mechanism accompanied by a relatively large volume change...

Abstract Anode‐free solid‐state batteries (AFSSBs) are considered to be one of the most promising high‐safety and high‐energy storage systems. However, low Coulombic efficiency stemming from severe deterioration on solid electrolyte/current collector (Cu foil) interface undesirable Li dendrite growth impede their practical application, especially when rigid garnet electrolyte is used. Here, an interfacial engineering strategy between Cu foil introduced for stable highly efficient AFSSBs. By...

Doping is generally used to tune and enhance the properties of metal oxides. However, their chemical composition cannot be readily modified beyond low dopant amounts without disrupting crystalline atomic structure. In case anatase TiO2, we introduce a new solution-based route allowing significantly modified, substituting divalent O2– anions by monovalent F– OH– resulting in formation cationic Ti4+ vacancies (□) whose concentration can controlled reaction temperature. The polyanionic has...

Anatase TiO2 is a potential negative electrode for sodium-ion batteries. The sodium storage mechanism is, however, still under debate, yet its comprehension required to optimize the electrochemical properties. To clarify occurring in anatase, we have used both and chemical routes from which obtained similar trends. During first discharge, an irreversible plateau region observed corresponds insertion of Na+ within interstitial sites anatase accompanied by drastic loss long-range order as...
