Abstract Ether based electrolytes have surfaced as alternatives to conventional carbonates allowing for enhanced electrochemical performance of sodium-ion batteries; however, the primary source improvement remains poorly understood. Here we show that coupling titanium dioxide and other anode materials with diglyme does enable higher efficiency reversible capacity than those combination involving ester electrolytes. Importantly, electrolyte dependent is revealed be result different structural...

Developing highly active and durable electrocatalysts for acidic oxygen evolution reaction remains a great challenge due to the sluggish kinetics of four-electron transfer severe catalyst dissolution. Here we report an electrochemical lithium intercalation method improve both activity stability RuO2 reaction. The intercalates into lattice interstices RuO2, donates electrons distorts local structure. Therefore, Ru valence state is lowered with formation stable Li-O-Ru structure, Ru-O...

Abstract The sodium‐ion battery is a promising technology owing to its low price and high abundance of sodium. However, the sluggish kinetics sodium ion makes it hard achieve high‐rate performance, therefore impairing power density. In this work, fiber‐in‐tube Co 9 S 8 ‐carbon(C)/Co designed with fast sodiation kinetics. experimental simulation analysis show that dominating capacitance mechanism for Na‐ion storage performance due abundant grain boundaries, three exposed layer interfaces,...

High-voltage lithium metal batteries suffer from poor cycling stability caused by the detrimental effect on cathode of water moisture present in non-aqueous liquid electrolyte solution, especially at high operating temperatures (e.g., ≥60 °C). To circumvent this issue, here we report hexamethyldisilazide (LiHMDS) as an additive. We demonstrate that addition a 0.6 wt% LiHMDS typical fluorine-containing carbonate-based solution enables stable Li||LiNi0.8Co0.1Mn0.1O2 (NCM811) coin cell...

Anchoring single metal atom to carbon supports represents an exceptionally effective strategy maximize the efficiency of catalysts. Recently, dual-atom catalysts (DACs) emerge as intriguing candidate for atomic catalysts, which perform better than single-atom (SACs). However, clarification polynary structures and their beneficial effects remains a daunting challenge. Here, atomically dispersed triple Zn-Co-Fe sites anchored nitrogen-doped (ZnCoFe-N-C) prepared by one-step pyrolysis designed...
