Redox flow batteries (RFBs) are considered one of the most promising large-scale energy storage technologies. However, conventional RFBs suffer from low density due to solubility active materials in electrolyte. On basis redox targeting reactions battery materials, lithium (RFLB) demonstrated this report presents a disruptive approach drastically enhancing batteries. With LiFePO4 and TiO2 as cathodic anodic Li respectively, tank RFLB could reach ~500 watt-hours per liter (50% porosity),...
Abstract Designing the electrocatalysts that are stable and active for extensively adaptable water splitting is highly desirable developing hydrogen based energy. IrO 2 a promising widely used catalyst oxygen evolution reaction in commercial applications, but rarely (HER), due to high Gibbs free energy adsorption (Δ G H* ).

Although dispersing Pt atomic clusters (ACs) on a conducting support is promising way to minimize the amount required in hydrogen evolution reaction (HER), catalytic mass activity and durability of ACs are often unsatisfactory for alkaline HER due their unfavorable water dissociation challenges stabilizing them against agglomeration detachment.

Here, we first deduce that introduction lanthanide gradually changing electronic configurations can continuously owing shielding...
Ruthenium (Ru) is widely recognized as a low-cost alternative to iridium anode electrocatalyst in proton-exchange membrane water electrolyzers (PEMWE). However, the reported Ru-based catalysts usually only operate within tens of hours PEMWE because their intrinsically high reactivity lattice oxygen that leads irrepressible Ru leaching and structural collapse. Herein, we report design concept by employing large-sized acid-resistant lead (Pb) second element induce pinning effect for...

Abstract Rechargeable neutral aqueous zinc−air batteries (ZABs) are a promising type of energy storage device with longer operating life and less corrosiveness compared conventional alkaline ZABs. However, the ZABs normally possess poor oxygen evolution reactions (OERs) reduction performance, resulting in large charge–discharge voltage gap low round‐trip efficiency. Herein, we demonstrate sunlight‐assisted strategy for achieving an ultralow 0.05 V by using FeOOH‐decorated BiVO 4 (Fe‐BiVO )...
