The development of high efficiency air cathode plays important role in regulating the surface electrochem. process to enhance the performance of Li-O2 battery. Herein, we synthesize an integrated porous Ni3S2 on 3D Ni foam substrate through a facile MOF-derived route, the integrated 3D foam-like porous Ni3S2 catalyst can functional as both current collector and catalyst layer. Benefiting from the unique porous structure and the uniform regulate role of the surface electrochem. reaction, the integrated 3D foam-like catalyst cathode delivers nearly 3 times higher discharge capacity and longer cycling performance than that of the pristine Ni foam. More importantly, the morphol. of the formed discharge products exhibits lamellar-like structure and has large radial dimension, the Ni3S2 catalyst layer also plays the role of inducing the formation of LiO2 and decreasing the charge overpotential. This study opens a different and facile horizon to fabricate high-efficient air cathode.

Yang, Yao published the artcileGolden Palladium Zinc Ordered Intermetallics as Oxygen Reduction Electrocatalysts, Product Details of C10H22O5, the main research area is golden palladium zinc ordered intermetallic oxygen reduction electrocatalyst nanocatalyst; Pt-free electrocatalysts; fuel cell; metal−air battery; ordered intermetallics; oxygen reduction reaction.

Exploring Pt-free electrocatalysts with high activity and long durability for the oxygen reduction reaction (ORR) has been long pursued by the renewable energy materials community. In this work, we have designed an ordered intermetallic PdZn/C (O-PdZn) with a several at.-layer Pd shell, which achieved a 3-fold enhancement in ORR mass activities (MA) in alk. media, relative to Pd/C and Pt/C. Further Au incorporation in O-PdZn/C (Au-O-PdZn/C) yielded a catalyst with superior durability with less than 10% loss in MA after 30000 potential cycles. These effects have attributed to the rationally designed ordered structure and stabilizing effect of Au atoms. Aberration-corrected scanning transmission electron microscopy and synchrotron-based X-ray fluorescence spectroscopy were employed to show that Au not only galvanically replaced Pd and Zn on the surface but also penetrated through the PdZn lattice and distributed uniformly within the particles. Au-O-PdZn/C was also tested as an effective oxygen cathode in broad applications in rechargeable Li-air and Zn-air batteries.

Li, Xuelian published the artcileBamboo-like nitrogen-doped carbon nanotube forests as durable metal-free catalysts for self-powered flexible Li-CO2 batteries, Synthetic Route of 143-24-8, the main research area is nitrogen carbon nanotube catalyst selfpowered lithium carbon dioxide battery; Li-CO2 batteries; flexible electrodes; metal-free bifunctional catalysts; nitrogen-doped carbon nanotubes; self-powered systems.

The Li-CO2 battery is a promising energy storage device for wearable electronics due to its long discharge plateau, high energy d., and environmental friendliness. However, its utilization is largely hindered by poor cyclability and mech. rigidity due to the lack of a flexible and durable catalyst electrode. Herein, flexible fiber-shaped Li-CO2 batteries with ultralong cycle-life, high rate capability, and large specific capacity are fabricated, employing bamboo-like N-doped carbon nanotube fiber (B-NCNT) as flexible, durable metal-free catalysts for both CO2 reduction and evolution reactions. Benefiting from high N-doping with abundant pyridinic groups, rich defects, and active sites of the periodic bamboo-like nodes, the fabricated Li-CO2 battery shows outstanding electrochem. performance with high full-discharge capacity of 23 328 mAh g-1, high rate capability with a low potential gap up to 1.96 V at a c.d. of 1000 mA g-1, stability over 360 cycles, and good flexibility. Meanwhile, the bifunctional B-NCNT is used as the counter electrode for a fiber-shaped dye-sensitized solar cell to fabricate a self-powered fiber-shaped Li-CO2 battery with overall photochem.-elec. energy conversion efficiency of up to 4.6%. Along with a stable voltage output, this design demonstrates great adaptability and application potentiality in wearable electronics with a breath monitor as an example.

Feng, Yaya published the artcileEnhanced Li2O2 Decomposition in Rechargeable Li-O2 Battery by Incorporating WO3 Nanowire Array Photocatalyst, Application In Synthesis of 143-24-8, the main research area is tungsten oxide nanowire lithium oxide oxidation photocatalyst low overpotential.

Reducing the high charging overpotential of nonaqueous Li-O2 batteries is very important for their energy storage ability. Herein, we propose a newly photoassisted Li-O2 battery system, in which a WO3 nanowires array that grows on carbon textile serves as a photocatalyst on the cathode. Because of its abundant holes excited by visible light, the Li2O2 coated on WO3 nanowires can be efficiently oxidized during the charging process, resulting in the reduced charging potential and enhanced Li-O2 battery performance. Notably, the charging potential can still maintain at 3.55 V even after 100 cycles in this photoassisted battery system, which is much lower than that of the dark state (4.4 V). These pos. results indicate that the introduction of WO3 nanowires array photocatalyst provides possibilities in improving the energy conversion efficiency of the Li-O2 battery.

Kim, Juhyoung published the artcileAn efficient electrocatalyst of NiO supported on carbon paper for nonaqueous Li-O2 batteries, Product Details of C10H22O5, the main research area is nickel oxide carbon lithium oxygen battery electrocatalyst polarization fabrication.

A Li-O2 battery has been considered as one of the most promising energy storage systems owing to their ultrahigh theor. energy densities. However, low energy efficiency (high polarization) during discharge/charge and resulting cycle stabilities have severely limited the development of this type of battery. Here, we demonstrate a simple preparation of NiO supported on carbon paper by dipping carbon paper in Ni acetate solution and heating it to apply NiO directly to the carbon as a cathode material for nonaqueous Li-O2 batteries. The prepared sample was confirmed as the structure of NiO-incorporated carbon using XPS, X-ray absorption spectroscopy (XAS), and high-resolution transmission electron microscopy (HR-TEM) anal. despite amorphous patterns seen in XRD (∼10% NiO in NiO supported on carbon paper). A Li-O2 cell in which the NiO supported on carbon paper was applied as an electrocatalyst showing an initial ∼ 6% increase in energy efficiency and a subsequent 50 cycle retention.

Zhang, Huang published the artcileSolvent-dictated sodium sulfur redox reactions: investigation of carbonate and ether electrolytes, Quality Control of 143-24-8, the main research area is redox reaction carbonate ether electrolyte sodium sulfur ion battery.

Sulfur-based cathode chemistries are essential for the development of high energy d. alkali-ion batteries. Here, we elucidate the redox kinetics of sulfur confined on carbon nanotubes, comparing its performance in ether-based and carbonate-based electrolytes at room temperature The solvent is found to play a key role for the electrochem. reactivity of the sulfur cathode in sodium-sulfur (Na-S) batteries. Ether-based electrolytes contribute to a more complete reduction of sulfur and enable a higher electrochem. reversibility. On the other hand, an irreversible solution-phase reaction is observed in carbonate solvents. This study clearly reveals the solvent-dependent Na-S reaction pathways in room temperature Na-S batteries and provides an insight into realizing their high energy potential, via electrolyte formulation design.

Hu, Anjun published the artcileImproved Cyclability of Lithium-Oxygen Batteries by Synergistic Catalytic Effects of Two-Dimensional MoS2 Nanosheets Anchored on Hollow Carbon Spheres, Application In Synthesis of 143-24-8, the main research area is lithium oxygen battery composite catalyst molybdenum disulfide; hollow carbon sphere synergistic effect.

The design and development of high-efficient electrocatalysts plays a decisive role in improving the stability of lithium-oxygen (Li-O2) batteries. Here, two-dimensional (2D) MoS2 nanosheets anchored on hollow carbon spheres (MoS2/HCS) composites is designed and reported as promising cathode catalysts for Li-O2 batteries. The MoS2/HCS-based Li-O2 battery shows superior electrochem. performance, in terms of high capacity (4010 mA h g-1) and enhanced cycling performance (104 cycles). XPS results reveal that the formation of Li2CO3 and other side products can be effectively alleviated when MoS2/HCS electrode is used as the cathode. On the basis of exptl. studies, it is found that the synergistic effects, which originated from the superior catalytic property of MoS2 nanosheets and the good elec. conductivity of HCS with high surface area, is the main reason for performance improvement. The synergistic effects induced by the dispersed MoS2 nanosheets anchored on nanostructured HCS cathodes provide a promising strategy for developing catalysts of O2 electrode for Li-O2 batteries with excellent performance.

Zhao, Guangyu published the artcileCapacitive Behavior Based on the Ultrafast Mass Transport in a Self-Supported Lithium Oxygen Battery Cathode, Category: ethers-buliding-blocks, the main research area is lithium oxygen battery cathode wood derived substrate; metal organic framework derivate capacitive behavior.

The pore structures of lithium oxygen battery cathodes play a significant role in their reversibility and lifespan by deciding the mass transport in cathodes. In the present work, a porous Co3O4/C modified wood-derived slice is used as self-supported lithium oxygen battery cathode. The straight tubes in vertical and horizontal directions inherited from wood vessels afford the cathodes facilitated paths for gas and ion transport, resp. Furthermore, the homogeneous distribution of mesoporous Co3O4/C polyhedrons on tube wall of wood-derived substrates creates a uniform reaction interface in the cathodes. The ultrafast mass transport and uniform reaction interface lead to a capacitive contribution in battery capacity, owing to the fast kinetics that is free from the semi-infinite diffusion control. Accordingly, these merits enable the cathodes to have good reversibility and cyclability. The batteries can cycle more than 380 rounds without obvious overpotential variation at a c.d. of 1.0 mA cm-2 within a capacity limitation of 1.0 mAh cm-2.

Mushtaq, Muhammad published the artcileComposite Cathode Architecture with Improved Oxidation Kinetics in Polymer-Based Li-O2 Batteries, Synthetic Route of 143-24-8, the main research area is cathode oxidation kinetics polymer electrolyte lithium ion battery safety; composite cathode lithium ion battery oxidation kinetics; Li−oxygen battery; composite cathode; hexamethylphosphoramide; oxidation kinetics; polymer electrolyte.

The Li-O2 battery based on the polymer electrolyte has been considered as the feasible solution to the safety issue derived from the liquid electrolyte. However, the practical application of the polymer electrolyte-based Li-O2 battery is impeded by the poor cyclability and unsatisfactory energy efficiency caused by the structure of the porous cathode. Herein, an architecture of a composite cathode with improved oxidation kinetics of discharge products was designed by an in situ method through the polymerization of the electrolyte precursor for the polymer-based Li-O2 battery. The composite cathode can provide sufficient gas diffusion channels, abundant reaction active sites, and continuous pathways for ion diffusion and electron transport. Furthermore, the oxidation kinetics of nanosized discharge products formed in the composite cathode can be improved by hexamethylphosphoramide during the recharge process. The polymer-based Li-O2 batteries with the composite cathode demonstrate highly reversible capacity when fully charged and a long cycle lifetime under a fixed capacity with low overpotentials. Moreover, the interface contact between hexamethylphosphoramide and the Li metal can be stabilized simultaneously. Therefore, the composite cathode architecture designed in this work shows a promising application in high-performance polymer-based Li-O2 batteries.

Zhou, Xuan published the artcileEvaluation of Computational Chemistry Methods for Predicting Redox Potentials of Quinone-Based Cathodes for Li-Ion Batteries, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is quinone cathode lithium ion battery redox potential computational chem.

High-throughput computational screening (HTCS) is an effective tool to accelerate the discovery of active materials for Li-ion batteries. For the evaluation of organic cathode materials, the effectiveness of HTCS depends on the accuracy of the employed chem. descriptors and their computing cost. This work was focused on evaluating the performance of computational chem. methods, including semi-empirical quantum mechanics (SEQM), d.-functional tight-binding (DFTB), and d. functional theory (DFT), for the prediction of the redox potentials of quinone-based cathode materials for Li-ion batteries. In addition, we evaluated the accuracy of three energy-related descriptors: (1) the redox reaction energy, (2) the LUMO (LUMO) energy of reactant mols., and (3) the HOMO (HOMO) energy of lithiated product mols. Among them, the LUMO energy of the reactant compounds, regardless of the level of theory used for its calculation, showed the best performance as a descriptor for the prediction of exptl. redox potentials. This finding contrasts with our earlier results on the calculation of quinone redox potentials in aqueous media for redox flow batteries, for which the redox reaction energy was the best descriptor. Furthermore, the combination of geometry optimization using low-level methods (e.g., SEQM or DFTB) followed by energy calculation with DFT yielded accuracy as good as the full optimization of geometry using the DFT calculations Thus, the proposed calculation scheme is useful for both the optimum use of computational resources and the systematic generation of robust calculation data on quinone-based cathode compounds for the training of data-driven material discovery models.
