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.

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.

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.

Wang, Qian published the artcileIntegrated 3D foam-like porous Ni3S2 as improved deposition support for high-performance Li-O2 battery, Application In Synthesis of 143-24-8, the main research area is porous nickel sulfide improved deposition support lithium oxygen battery.

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.

Liu, Dezhong published the artcileStable Room-Temperature Sodium-Sulfur Batteries in Ether-Based Electrolytes Enabled by the Fluoroethylene Carbonate Additive, SDS of cas: 143-24-8, the main research area is stable room temperature sodium sulfur battery ether electrolytes enabled; cathode−electrolyte interphase; electrolyte additive; room-temperature sodium−sulfur batteries; sulfurized polyacrylonitrile cathode; “solid−solid” conversion.

Because of its high energy d. and low cost, the room-temperature sodium-sulfur (RT Na-S) battery is a promising candidate to power the next-generation large-scale energy storage system. However, its practical utilization is hampered by the short life span owing to the severe shuttle effect, which originates from the “”solid-liquid-solid”” reaction mechanism of the sulfur cathode. In this work, fluoroethylene carbonate is proposed as an additive, and tetraethylene glycol di-Me ether is used as the base solvent. For the sulfurized polyacrylonitrile cathode, a robust F-containing cathode-electrolyte interphase (CEI) forms on the cathode surface during the initial discharging. The CEI prohibits the dissolution and diffusion of the soluble intermediate products, realizing a “”solid-solid”” reaction process. The RT Na-S cell exhibits a stable cycling performance: a capacity of 587 mA h g-1 is retained after 200 cycles at 0.2 A g-1 with nearly 100% Coulombic efficiency.

Jiang, Yongxiang published the artcileMildly Oxidized MXene (Ti3C2, Nb2C, and V2C) Electrocatalyst via a Generic Strategy Enables Longevous Li-O2 Battery under a High Rate, Product Details of C10H22O5, the main research area is sodium ion battery cathode oxidized MXene electrocatalyst; Li−O2 battery; electrocatalysts; high current density; longevous; mildly oxidized MXene.

Lithium-oxygen batteries (LOBs) with ultrahigh theor. energy d. have emerged as one appealing candidate for next-generation energy storage devices. Unfortunately, some fundamental issues remain unsettled, involving large overpotential and inferior rate capability, mainly induced by the sluggish reaction kinetics and parasitic reactions at the cathode. Hence, the pursuit of suitable catalyst capable of efficiently catalyzing the oxygen redox reaction and eliminating the side-product generation, become urgent for the development of LOBs. Here, we report a universal synthesis approach to fabricate a suite of mildly oxidized MXenes (mo-Nb2CTx, mo-Ti3C2Tx, and mo-V2CTx) as cathode catalysts for LOBs. The readily prepared mo-MXenes possess expanded interlayer distance to accommodate massive Li2O2 formation, and in-situ-formed light metal oxide to enhance the electrocatalytic activity of MXenes. Taken together, the mo-V2CTx manages to deliver a high specific capacity of 22752 mAh g-1 at a c.d. of 100 mA g-1, and a long lifespan of 100 cycles at 500 mA g-1. More impressively, LOBs with mo-V2CTx can continuously operate for 90, 89, and 70 cycles, resp., under a high c.d. of 1000, 2000, and 3000 mA g-1 with a cutoff capacity of 1000 mAh g-1. The theor. calculations further reveal the underlying mechanism lies in the optimized surface, where the overpotentials for the formation/decomposition of Li2O2 are significantly reduced and the catalytic kinetics is accelerated. This contribution offers a feasible strategy to prepare MXenes as efficient and robust electrocatalyst toward advanced LOBs and other energy storage devices.

Oh, Gwangseok published the artcileSeed Layer Formation on Carbon Electrodes to Control Li2O2 Discharge Products for Practical Li-O2 Batteries with High Energy Density and Reversibility, Related Products of ethers-buliding-blocks, the main research area is carbon electrode lithium oxide oxygen battery; Li2O2; carbon electrode; interface; lithium air battery; nucleation; seed layer.

The high theor. energy densities of lithium-air batteries (LAB) make this technol. an attractive energy storage system for future mobility applications. Li2O2 growth process on the cathode relies on the surrounding chem. environment of electrolytes. Low conductivity and strong reactivity of Li2O2 discharge products can cause overpotential and induce side reactions in LABs, resp., eventually leading to poor cyclability. The capacity and reversibility of LABs are highly susceptible to the morphol. of the Li2O2 discharge products. Here, we identify for the first time that a seed layer formed by the combination of a cathode and an electrolyte determines the morphol. of Li2O2 discharge products. This seed layer led to its high reversibility with a large areal capacity (up to 10 mAh/cm2). Excellent OER (oxygen evolution reaction) was achieved by the formation of a favorable interface between the carbon electrode and electrolyte, minimizing the decomposition of the electrolyte. These remarkable improvements in LAB performance demonstrate critical progress toward advancing LAB into practical uses, which would exploit good reversibility of LABs in pouch-type cell arrangements with 1.34 Ah.

Huang, Lulu published the artcileYucca-like CoO-CoN Nanoarray with Abundant Oxygen Vacancies as a High-Performance Cathode for Lithium-Oxygen Batteries, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium oxygen battery yucca like array cathode catalyst.

In this paper, we report a three-dimensional, yucca-like CoO-CoN composite cathode prepared by the in situ growth of a Co(OH)F array on pretreated carbon paper, followed by controllable partial nitridation in ammonia flow. The material exhibited excellent oxygen reduction and evolution activity and, in particular, excellent cathode performance for aprotic Li-O2 batteries. Our optimal sample yielded a specific capacity of up to 5423 mA h g-1 and functioned for 200 cycles with no degradation It was found that the introduction of oxygen vacancies on the surface of CoO-CoN through nitridation played a crucial role in the material’s high performance, especially its high stability and long cyclability. We attribute the high performance to the following: first, the material’s nanoarray architecture, which provided a large surface area and featured enough interspaces to ensure a high d. of active sites as well as to assist with oxygen and ion diffusion, and with the hosting of discharge products, and second, the abundant oxygen vacancies generated on the CoO-CoN surface during partially controlled nitridation, which significantly enhanced the material’s oxygen reduction/evolution reaction activity and stability.

Kunanusont, Nattanai published the artcilePorous Carbon Cathode Assisted with Ionogel Binder Fabricated from Supercritical Fluid Technique toward Li-O2/CO2 Battery Application, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is ionic liquid ionogel binder porous carbon cathode; lithium oxygen battery supercritical carbon dioxide.

Lithium-O2/CO2 battery has been recently developed due to its higher capacity than Li-O2 battery and high impact on energy and environmental problems. Ionogels composed of ionic liquid ([bmim][Tf2N], [bmim][PF6] or [bmim][I]), and poly(vinylidene fluoride) (PVDF) is applied as a binder of carbon particles on cathode of Li-O2/CO2 battery. A porous carbon cathode with ionogel binder was fabricated by drying and impregnation techniques in supercritical carbon dioxide at 40°C and 20.0 MPa. The effect of ionic liquid on cathode properties was investigated by various ratios of ionic liquid amount in the ionogel binder. The porous carbon cathodes were further used to test the discharge capacity of Li-O2/CO2 batteries. We found that the capacity of battery was enhanced as the amount of ionic liquid in the gel binder increased, while the cathode with PVDF-[bmim][Tf2N] ionogel binder had the highest discharge capacity at 15.07 mAh cm-2. The mechanism of capacity enhancement relies on the reduction of interfacial resistance between electrolyte and cathode and the improvement of reaction gases solubilities into the ionogel binder on the porous carbon cathode.

Hashimoto, Kei published the artcileDesign of polymer network and Li+ solvation enables thermally and oxidatively stable, mechanically reliable, and highly conductive polymer gel electrolyte for lithium batteries, Formula: C10H22O5, the main research area is design polymer network li solvation enables thermally oxidatively stable.

Herein, we demonstrate that design of polymer network and Li+-ion solvation enables the fabrication of thermally and oxidatively stable, mech. reliable, and highly conductive polymer gel electrolytes for lithium batteries. Polymer gel electrolytes have been used for Li-ion batteries (LIB) due to their quasi-solid natures and flexible shapes. However, they frequently suffer from the high vapor pressures of the incorporated solvents, low oxidative stabilities, and poor mech. properties. To overcome these drawbacks, we fabricated a tough gel electrolyte comprising a tetra-arm poly(ethylene glycol) (TPEG) homogeneous polymer network, in which a tetraglyme(G4)-based solvate ionic liquid (SIL) was incorporated. It was intriguing to find that the solvation of Li+ ion by oxygen atoms (within G4 and TPEG), represented as [O]/[Li], governed the thermal and oxidative stabilities of the gel electrolyte, while the homogeneous network contributed to the mech. reliability and high ionic conductivity At [O]/[Li] = 5, the TPEG-based gel electrolyte with no free solvent simultaneously exhibited high thermal (>200°C) and oxidative stabilities (>4.4 V), high stretchability, and high ionic conductivity (~1 mS cm-1 at 30°C). These favorable properties of the gel electrolyte resulted in reversible charge/discharge of a 4-V-class high-voltage cathode (LiNi0.6Mn0.2Co0.2O2, NMC622).
