Aqueous Zn-iodine (Zn-I2 ) batteries have been regarded as a promising energy-storage system owing to their high energy/power density, safety, and cost-effectiveness. However, the polyiodide shuttling results in serious active mass loss Zn corrosion, which limits cycling life of Zn-I2 batteries. Inspired by chromogenic reaction between starch iodine, structure confinement strategy is proposed suppress hiring starch, due its unique double-helix structure. In situ Raman spectroscopy...
Abstract Despite the recent achievements in urea electrosynthesis from co-reduction of nitrogen wastes (such as NO 3 − ) and CO 2 , product selectivity remains fairly mediocre due to competing nature two parallel reduction reactions. Here we report a catalyst design that affords high by sequentially reducing at dynamic catalytic centre, which not only alleviates competition issue but also facilitates C−N coupling. We exemplify this strategy on nitrogen-doped carbon catalyst, where...
Coupling Ni-rich layered oxide cathodes with Si-based anodes is one of the most promising strategies to realize high-energy-density Li-ion batteries. However, unstable interfaces on both cathode and anode sides cause continuous parasitic reactions, resulting in structural degradation capacity fading full cells. Herein, lithium tetrafluoro(oxalato) phosphate synthesized applied as a multifunctional electrolyte additive mitigate irreversible volume swing SiOx suppress undesirable interfacial...
Li-rich materials, Li<sub>1.140</sub>Mn<sub>0.622</sub>Ni<sub>0.114</sub>Co<sub>0.124</sub>O<sub>2</sub>, of a layered/spinel heterostructure were synthesized by one-step solvothermal route with subsequent moderate heat treatment.
Li2CO3 is the cathodic discharge product of a Li-CO2/O2 battery and difficult to electrochemically decompose. The accumulation leads degradation results in short lifespan. Herein, carbon nanotube supported Ru/NiO@Ni catalyst (Ru/NiO@Ni/CNT) synthesized with Ru nanoparticles (∼2.5 nm) anchored on surface core–shell structure NiO@Ni (∼17 nm). We found strong interfacial interactions between NiO. XRD XPS analysis revealed that presence could protect Ni species from being deeply oxidized while...
Guar gum (GG) has been applied as a binder for layered lithium-rich cathode materials of Li-ion batteries the first time.
Although holding a high capacity, Li-rich materials are far from the demand of practical market because their inherent drawbacks, such as poor initial efficiency and rate capability. Herein, Li1.16Mn0.6Ni0.12Co0.12O2 have been prepared via one-step solvothermal strategy. The detail characterizations demonstrate that as-prepared present morphology nanoparticle-aggregated hierarchical microspheres heterostructure layered Li4Mn5O12-type spinel components. Compared to pure-layered structure,...
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 As one of the most promising cathodes for Li‐ion batteries, Li‐rich layered oxides suffer from low Coulombic efficiency, severe capacity fading, and voltage decay, which are related to aggregated Li@Mn 6 superstructure units. Herein, a Co‐free oxide Li[Li 1/4 Mn 1/2 Ni 1/6 Al 1/12 ]O 2 through substitution Co in , is designed. Combining average structural refinement with detailed local structural/chemical analysis, it found that introduced ions occupy sites units, further induces...
Abstract Metallic lithium/sodium (Li/Na) is considered an attractive anode for future high‐energy‐density batteries. The root causes of preventing their applications come from uneven Li/Na nucleation and subsequent dendrite formation.
