An aqueous Zn-MnO2 battery with high energy density and good cyclability has been successfully developed with use of an ‘oversaturated gel electrolyte’ (OSGE) prepared by cost-effective acetates and poly(acrylic acid) at 75°C. The electrochemica

N,N-Dimethylacetamide (DMA) cooperated with LiNO3 salt has previously shown to be a promising electrolyte for a Li//O2 battery, showing good stability against both the O2 electrode reaction and Li stripping/plating. In this work, DMA is hybridized wi

The energy density of an aqueous rechargeable battery is closely related to the working voltage which is limited by electrochemcial stability windows of aquoese electrolytes. In this study, an ‘oversaturated gel electrolyte’ (OSGE) is simply prep

Through Pechini method, a single phase shuttle-shaped perovskite oxide SrFe 0.8 Cu 0.1 Nb 0.1 O 3 − δ was successfully synthesised at 1000 °C. It was combined with active carbon, forming a composite electrode to be used as cathode in a room tempe

Ammonia is a natural pollutant in wastewater and removal technique such as ammonia electro‐oxidation is of paramount importance. The development of highly efficient and low‐costing electrocatalysts for the ammonia oxidation reaction (AOR) and hyd
For the first time, new Sm doped cerium oxynitrides with the formula Ce1-zSmzO2-xNy (z ≤ 0.5) are synthesized in order to maximize the concentration of anion vacancies. Single phase Sm-doped CeO2-xNy were confirmed by XRD, HRTEM and Rietveld refine

Due to its essential use as a fertilizer, ammonia synthesis from nitrogen and hydrogen is considered to be one of the most important chemical processes of the last 100 years. Since then, an enormous amount of work has been undertaken to investigate a
Aqueous rechargeable Zn/MnO2 batteries are attractive due to their low-cost, high safety and use of non-toxic materials. In term of electrolyte materials, it is anticipated that an aqueous electrolyte with a wider electrochemical window will improve

In this work, for the first time, an “oversaturated gel electrolyte” (OSGE) with extended electrochemical windows for use as electrolytes in aqueous batteries was investigated. The stability window of the 10 m LiClO4–PVA OSGE is 3.3 V when satu
