Recent years have witnessed a booming interest in grid-scale electrochemical energy storage, where much attention has been paid to the aqueous zinc ion batteries (AZIBs). Among various cathode materials for AZIBs, manganese oxides risen prominence due their high density and low cost. However, sluggish reaction kinetics poor cycling stability dictate against practical application. Herein, we demonstrate combined use of defect engineering interfacial optimization that can simultaneously...
Aqueous Zn batteries (AZBs) are a promising energy storage technology, due to their high theoretical capacity, low redox potential, and safety. However, dendrite growth parasitic reactions occurring at the surface of metallic result in severe instability. Here we report new method achieve ultrafine nanograin anodes by using ethylene glycol monomethyl ether (EGME) molecules manipulate zinc nucleation processes. It is demonstrated that EGME complexes with Zn2+ moderately increase driving force...
Abstract Aqueous zinc‐ion battery (AZB) is a promising candidate for next‐generation energy storage owing to inherent safety and low cost. However, AZBs are currently plagued by Zn dendrite growth undesirable side‐reactions, leading poor cycling stability premature failure. To restrain the uncontrollable growth, unique separator developed based on polyacrylonitrile/graphene oxide (abbreviated as PG) composite nanofibers, which contain abundance of zincophilicity functional groups regulate...
Abstract The intercalation of protons represents a notable component for energy storage in aqueous zinc‐ion batteries. However, the mechanism proton transport metal oxide cathodes, especially related to how cation distribution modulates proton‐conducting lanes, remains far from consensus due lack suitable model materials. Here, taking spinel ZnMn 2 O 4 cathode as prototype, it is disclosed that deficiency one half lattice Zn ions can triple its specific capacity at high rates, which...
Sodium-ion batteries (SIBs) have garnered extensive attentions in recent years as a low-cost alternative to lithium-ion batteries. However, achieving both high capacity and long cyclability cathode materials remains challenge for SIB commercialization. P3-type Na0.67Ni0.33Mn0.67O2 cathodes exhibit prominent Na+ diffusion kinetics but suffer from serious decay structural deterioration due stress accumulation phase transformations upon cycling. In this work, dual modification strategy with...
Three electrophosphorescent small molecular Ir(3+) complexes, Ir(HexPhBI)(3) 1 (HexPhBI = 1-Hexyl-2-phenyl-1H-benzo[d]imidazole), Ir(CzPhBI)(3) 2 (CzPhBI 9-(6-(2-phenyl-1H-benzo[d]imidazol-1-yl)hexyl)-9H-carbazole), and Ir(Cz(2)PhBI)(3) 3 (Cz(2)PhBI 9-(6-(4-(1-(6-(9H-carbazol-9-yl)hexyl)-1H-benzo[d]imidazol-2-yl)phenoxy)hexyl)-9H-carbazole), were synthesized in which was designed with the structure of multiposition encapsulation. Compared to hexyl-substituted 1, end-capped conjugated...
Being considered as a promising anode material for next‐generation lithium‐ion batteries, silicon oxide (SiO x ) suffers from low initial coulombic efficiency and unstable solid–electrolyte interphase (SEI), which hinder its commercial use. To address these issues, herein, an optimized chemical prelithiation method is developed using molecularly engineered lithium–biphenyl‐type complex, facilitates improved efficiency. More importantly, owing to the reaction between agent sodium carboxymethyl...

The effect vanadium addition on microstructure magnetic properties evolution was studied. Based characterization results, additive mainly reacted with rare earth (RE)‐rich phase to form ferrovanadium (FeV) phase, which rooted in boundary. inserted influence dissolution‐precipitation process acted as pinning sites heterogeneous nucleation...
Manganese oxides are promising host materials in rechargeable aqueous batteries due to their low cost and high capacity; however, practical applications have long been restricted by sluggish reaction kinetics poor cycling stability. Herein, the layered K0.36H0.26MnO2·0.28H2O (K36) with a proton Zn2+ cointercalation mechanism leads progressive phase evolution from layer-type K36 hybrid KxHyZnzMnO2·nH2O spinel-type ZnMn2O4 nanocrystal after long-term cycle. Accordingly, shows specific capacity...
Abstract The zinc dendrite growth generally relies upon a “positive‐feedback” mode, where the fast‐grown tips receive higher current densities and ion fluxes. In this study, self‐limiting polyacrylamide (PAM) hydrogel that presents negative feedback to is developed. monomers are purposefully polymerized at tips, then reduces local density flux by limiting diffusion with abundant functional groups. As consequence, accumulation restricted, (002) facets‐oriented deposition achieved. Moreover,...
