Abstract Zinc–air batteries deliver great potential as emerging energy storage systems but suffer from sluggish kinetics of the cathode oxygen redox reactions that render unsatisfactory cycling lifespan. The exploration on bifunctional electrocatalysts for reduction and evolution constitutes a key solution, where rational design strategies to integrate various active sites into high‐performance air remain insufficient. Herein, multiscale construction strategy is proposed rationally direct...
For applying metal–air batteries using seawater-based electrolytes, the influence of chloride anions on ORR/OER electrocatalytic mechanisms and rational design strategies for chloride-resistant electrocatalysts are summarized.
Abstract The rechargeable zinc–air battery (ZAB) is a promising energy storage technology owing to its high density and safe aqueous electrolyte, but there significant performance bottleneck. Generally, cathode reactions only occur at multiphase interfaces, where the electrocatalytic active sites can participate in redox effectively. In conventional air cathode, 2D interface on surface of gas diffusion layer (GDL) inevitably results an insufficient amount poor interfacial contact, leading...
The interfacial interaction in supported catalysts is of great significance for heterogeneous catalysis because it can induce charge transfer, regulate electronic structure active sites, influence reactant adsorption behavior, and eventually affect the catalytic performance. It has been theoretically experimentally elucidated well metal/oxide oxide/metal inverse catalysts, but rarely reported carbon-supported due to inertness traditional carbon materials. Using an example a...
Despite their high theoretical capacity density (1675 mAh g–1), the application of Li–S batteries has been seriously hindered by shuttle effect polysulfides. Here, inspired working principle natural spider webs, we synthesized a spider-web-like nanocomposite in which many hollow mesoporous silica (mSiO2) nanospheres/Co nanoparticles were threaded interconnected nitrogen-doped carbon nanotubes (NCNTs). Then (denoted as Co/mSiO2–NCNTs) was coated on commercial separator simple infiltration to...
For single-atom catalysts (SACs), the catalyst supports are not only anchors for single atoms, but also modulators geometric and electronic structures, which determine their catalytic performance. Selecting an appropriate support to prepare SACs with uniform coordination environments is critical achieving optimal performance clarifying relationship between structure property of SACs. Approaching such a goal still significant challenge. Taking advantage strong d-π interaction Cu atoms...
Abstract Pairing Li-free transition-metal-based cathodes (MX) with Li-metal anodes is an emerging trend to overcome the energy-density limitation of current rechargeable Li-ion technology. However, development practical MX plagued by existing notion low voltage due long-term overlooked voltage-tuning/phase-stability competition. Here, we propose a p-type alloying strategy involving three voltage/phase-evolution stages, which each varying trends are quantitated two improved ligand-field...
Owing to unique alkyne-rich structure, graphdiyne (GDY) has been proven be a superb support for anchoring metal catalysts. Herein we demonstrate new role of GDY as the wettability modifier enhanced hydrogenation catalysis. After loading certain amount nanospheres, silica mesoporous channels become superaerophilic, which allows gaseous H2 directly stored inside, thus significantly increasing concentration around palladium nanoparticles (NPs). At same time, nanospheres also alter electronic...
Primary lithium fluorinated graphite (Li/CFx ) batteries with superior energy density are an indispensable supply for multiple fields but suffer from sluggish reaction kinetics of the CFx cathode. Designing composite cathodes emerges as a solution to this problem. Despite optimal component , manganese oxide family represented by MnO2 is still faced intrinsic electronic conductivity bottleneck, which severely limits power Here, cation-induced high-dimensional constraining strategy perspective...
Abstract Modifying sulfur cathodes with lithium polysulfides (LiPSs) adsorptive and electrocatalytic host materials is regarded as one of the most effective approaches to address challenging problems in lithium‐sulfur (Li‐S) batteries. However, because high operating voltage window Li–S batteries from 1.7 2.8 V, cannot participate redox reactions within same potential region, which exhibit fixed or single functional property, hardly fulfilling requirement complex multiphase process. Herein,...
Aqueous zinc–air batteries (ZABs) are highly regarded as a promising electrochemical energy storage device owing to high density, low cost, and intrinsic safety. The employment of seawater replace the currently used deionized water in electrolyte will bring great economic benefits broaden application occasions ZABs. However, ZABs using seawater-based remain uninvestigated without an applicable cathode electrocatalyst or successful battery prototype. Herein, is successfully employed with...
In allusion to traditional transition-metal oxide (TMO) anodes for lithium-ion batteries, which face severe volume variation and poor conductivity, herein a bimetal dual-composite strategy based on two-dimensional (2D)-mosaic three-dimensional (3D)-gradient design is proposed. Inspired by natural mosaic dominance phenomena, Zn1-xCoxO/ZnCo2O4 2D-mosaic-hybrid mesoporous ultrathin nanosheets serve as building blocks assemble into 3D Zn-Co hierarchical framework. Moreover, series of derivative...
