Abstract In electrochemical energy storage and conversion systems, the anodic oxygen evolution reaction (OER) accounts for a large proportion of consumption. The electrocatalytic urea oxidation (UOR) is one promising alternatives to OER, owing its low thermodynamic potential. However, sluggish UOR kinetics, potential in practical use has not been unlocked. Herein, we developed tungsten‐doped nickel catalyst (Ni‐WO x ) with superior activity towards UOR. Ni‐WO exhibited record fast kinetics...
Metallic tin has been considered as one of the most promising anode materials both for lithium (LIBs) and sodium ion battery (NIBs) because a high theoretical capacity an appropriate low discharge potential. However, Sn anodes suffer from rapid fading during cycling due to pulverization induced by severe volume changes. Here we innovatively synthesized pipe-wire TiO2-Sn@carbon nanofibers (TiO2-Sn@CNFs) via electrospinning atomic layer deposition suppress pulverization-induced decay. In...
Engineering a stable solid electrolyte interphase (SEI) is critical for suppression of lithium dendrites. However, the formation desired SEI by formulating composition very difficult due to complex electrochemical reduction reactions. Here, instead trial-and-error composition, we design Li-11 wt % Sr alloy anode form SrF2-rich in fluorinated electrolytes. Density functional theory (DFT) calculation and experimental characterization demonstrate that has large interfacial energy with Li metal...
A water-in-salt electrolyte (WiSE) offers an electrochemical stability window much wider than typical aqueous electrolytes but still falls short in accommodating high-energy anode materials, mainly because of the enrichment water molecules primary solvation sheath Li+. Herein, we report a new strategy which non-Li cosalt was introduced to alter Li+-solvation structure. The presence asymmetric ammonium salt (Me3EtN·TFSI) increases solubility LiTFSI by two times, pushes salt/water molar ratio...
Metallic lithium is the most competitive anode material for next-generation (Li)-ion batteries. However, one of its major issues Li dendrite growth and detachment, which not only causes safety issues, but also continuously consumes electrolyte Li, leading to low coulombic efficiency (CE) short cycle life metal Herein, metallic suppressed by forming a fluoride (LiF)-enriched solid interphase (SEI) through lithiation surface-fluorinated mesocarbon microbeads (MCMB-F) anodes. The robust...

Li-rich layered-oxide cathodes have the highest theoretical energy density among all intercalated cathodes, which attracted intense interests for high-energy Li-ion batteries. However, O3-structured suffer from a low initial Coulombic efficiency (CE), severe voltage fade, and poor cycling stability because of continuous oxygen release, structural rearrangements due to irreversible transition-metal migration, serious side reactions between delithiated cathode electrolyte. Herein, we report...
Abstract Zinc–air batteries with high‐density energy are promising storage devices for the next generation of technologies. However, battery performance is highly dependent on efficiency oxygen electrocatalyst in air electrode.

More importantly, primary rechargeable Zn–air using TD‐CFs as air–cathode catalysts...

Abstract Water‐in‐salt electrolytes (WISE) have largely widened the electrochemical stability window (ESW) of aqueous by formation passivating solid electrolyte interphase (SEI) on anode and also absorption hydrophobic anion‐rich double layer cathode. However, cathodic limiting potential WISE is still too high for most high‐capacity anodes in sodium‐ion batteries (ASIBs), cost practical application. Herein, a low‐cost 19 m (m: mol kg −1 ) bi‐salts with wide ESW 2.8 V was designed, where 17...

Abstract Selective two-electron (2e − ) oxygen reduction reaction (ORR) offers great opportunities for hydrogen peroxide (H 2 O electrosynthesis and its widespread employment depends on identifying cost-effective catalysts with high activity selectivity. Main-group metal nitrogen coordinated carbons (M-N-Cs) are promising but remain largely underexplored due to the low metal-atom density lack of understanding in structure-property correlation. Here, we report using a nanoarchitectured Sb S 3...
