Tang, Xiao published the artcileA universal strategy towards high-energy aqueous multivalent-ion batteries, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is energy storage mol dynamics multivalent ion battery.

Rechargeable multivalent metal (e.g., Ca, Mg or, Al) batteries are ideal candidates for large-scale electrochem. energy storage due to their intrinsic low cost. However, their practical application is hampered by the low electrochem. reversibility, dendrite growth at the metal anodes, sluggish multivalent-ion kinetics in metal oxide cathodes and, poor electrode compatibility with non-aqueous organic-based electrolytes. To circumvent these issues, here we report various aqueous multivalent-ion batteries comprising of concentrated aqueous gel electrolytes, sulfur-containing anodes and, high-voltage metal oxide cathodes as alternative systems to the non-aqueous multivalent metal batteries. This rationally designed aqueous battery chem. enables satisfactory specific energy, favorable reversibility and improved safety. As a demonstration model, we report a room-temperature calcium-ion/sulfur| |metal oxide full cell with a specific energy of 110 Wh kg-1 and remarkable cycling stability. Mol. dynamics modeling and exptl. investigations reveal that the side reactions could be significantly restrained through the suppressed water activity and formation of a protective inorganic solid electrolyte interphase. The unique redox chem. of the multivalent-ion system is also demonstrated for aqueous magnesium-ion/sulfur||metal oxide and aluminum-ion/sulfur||metal oxide full cells.

Electrocatalysis for cathodic oxygen is of great significance for achieving high-performance lithium-oxygen batteries. Herein, we report a facile and green method to prepare an interconnected nanoporous three-dimensional (3D) architecture, which is composed of RuO2 nanogranulates coated with few layers of carbon. The as-prepared 3D nanoporous RuO2@C nanostructure can demonstrate a high initial specific discharge capacity of 4000 mA h g-1 with high round-trip efficiency of 95%. Meanwhile, the nanoporous RuO2@C could achieve stable cycling performance with a fixed capacity of 1500 mA h g-1 over 100 cycles. The terminal discharge and charge potentials of nanoporous RuO2@C are well maintained with minor potential variation of 0.14 and 0.13 V at the 100th cycle, resp. In addition, the formation of discharge products is monitored by using in situ high-energy synchrotron X-ray diffraction (XRD).

Kim, Hee-Sang published the artcileEffect of Urea as Electrolyte Additive for Stabilization of Lithium Metal Electrodes, COA of Formula: C10H22O5, the main research area is urea electrolyte additive lithium metal electrode stabilization.

Owing to its lowest standard redox potential, low d., and high theor. specific capacity, lithium metal has been considered to be the ideal anode material for secondary lithium batteries. However, lithium metal is thermodynamically unstable in liquid organic electrolytes (LOEs). When lithium metal comes in contact with an LOE, it reacts easily with it to form the solid electrolyte interphase (SEI) layer. Once the stable and robust SEI layer forms, it can inhibit the direct contact between lithium metal and LOE and the further decomposition of the electrolyte. Nevertheless, the inhomogeneity in chem. composition or thickness of the SEI layer can cause the growth of lithium dendrites, which lead to short-circuits in batteries. In this study, we suggested the use of urea as a new electrolyte additive to restrain the growth of lithium dendrites via the formation of a uniform and robust SEI layer on the lithium surface. The Li sym. cell with 0.5 M urea electrolyte additive exhibited better cyclability over 415 cycles at 1 mA cm-2; this number of cycles was >40 times larger than that of the Li sym. cell without urea additive. Further, the Li-O2 cell with electrolyte additive was cycled for more than 200 cycles at 0.1 mA cm-2 under the limited capacity mode of 1000 mA h g-1. The enhancement of the cyclability of Li metal-based batteries using urea as an electrolyte additive suppresses the growth of lithium dendrites.

Matsuda, Shoichi published the artcileHighly Efficient Oxygen Evolution Reaction in Rechargeable Lithium-Oxygen Batteries with Triethylphosphate-Based Electrolytes, Product Details of C10H22O5, the main research area is lithium oxygen battry triethylphosphate based electrolyte.

Aprotic lithium-oxygen (Li-O2) batteries are promising candidates for next-generation energy storage devices because of their much higher potential energy d. than Li-ion batteries. However, the practical application of rechargeable Li-O2 batteries has been limited by poor cycle performance, especially the side reactions that lower the oxygen reaction efficiency at the pos. electrode. The present study demonstrated that when the triethylphosphate-based electrolyte contains lithium nitrate and triethylphosphate forms a solvated complex by coordinating with Li ions, the O2 evolution rate could reach almost 100% of that of the ideal two-electron reaction (O2/e- = 0.5) during the most part of the charging process, with the total oxygen evolution yield exceeding 90%. These results are useful for designing electrolytes for rechargeable Li-O2 batteries with high energy densities.

Zhang, Zhang published the artcileLi-N2 Batteries: A Reversible Energy Storage System?, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is battery energy storage graphene nitrogen fixation surface analysis; batteries; energy storage; graphene; nitrogen fixation; surface analysis.

Tremendous energy consumption is required for traditional artificial N2 fixation, leading to addnl. environmental pollution. Recently, new Li-N2 batteries have inextricably integrated energy storage with N2 fixation. In this work, graphene is introduced into Li-N2 batteries and enhances the cycling stability. However, the instability and hygroscopicity of the discharge product Li3N lead to a rechargeable but irreversible system. Moreover, strong nonpolar N N covalent triple bonds with high ionization energies also cause low efficiency and irreversibility of Li-N2 batteries. In contrast, the modification with in situ generated Li3N and LiOH restrained the loss and volume change of Li metal anodes during stripping and plating, thereby promoting the rechargeability of the Li-N2 batteries. The mechanistic study here will assist in the design of more stable Li-N2 batteries and create more versatile methods for N2 fixation.

Liu, Ying published the artcileEnabling Stable Interphases via In Situ Two-Step Synthetic Bilayer Polymer Electrolyte for Solid-State Lithium Metal Batteries, SDS of cas: 143-24-8, the main research area is bilayer polymer electrolyte interphase solid state lithium metal battery.

Poly(ethylene oxide) (PEO)-based electrolyte is considered to be one of the most promising polymer electrolytes for lithium metal batteries. However, a narrow electrochem. stability window and poor compatibility at electrode-electrolyte interfaces restrict the applications of PEO-based electrolyte. An in situ synthetic double-layer polymer electrolyte (DLPE) with polyacrylonitrile (PAN) layer and PEO layer was designed to achieve a stable interface and application in high-energy-d. batteries. In this special design, the hydroxy group of PEO-SPE can form an O-H—N hydrogen bond with the cyano group in PAN-SPE, which connects the two layers of DLPE at a microscopic chem. level. A special Li+ conducting mechanism in DLPE provides a uniform Li+ flux and fast Li+ conduction, which achieves a stable electrolyte/electrode interface.LiFePO4/DLPE/Li battery shows superior cycling stability, and the coulombic efficiency remains 99.5% at 0.2 C. Meanwhile, LiNi0.6Co0.2Mn0.2O2/DLPE/Li battery shows high specific discharge capacity of 176.0 mAh g-1 at 0.1 C between 2.8 V to 4.3 V, and the coulombic efficiency remains 95% after 100 cycles. This in situ synthetic strategy represents a big step forward in addressing the interface issues and boosting the development of high-energy-d. lithium-metal batteries.

Park, Jehee published the artcileHybridization of cathode electrochemistry in a rechargeable seawater battery: Toward performance enhancement, HPLC of Formula: 143-24-8, the main research area is seawater battery energy efficiency solid electrolyte electrocatalyst; elec double layer capacitance.

Seawater batteries (SWBs) are promising energy storage systems for the future because of their eco-friendly utilization of abundant seawater as low-cost sources of Na ion active cathode materials. However, the overall efficiency (i.e. voltage and/or energy efficiency) and power performance of SWBs are limited by the sluggish kinetics of the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) on the current collector of the SWB cathode. Generally, the charge storage and delivery process through the elec. double layer (EDL) are much faster compared to OER/ORR and other Faradic reactions. To improve the performance of SWBs, we utilized the benefit of EDL formation along with OER/ORR activities using com. high surface area (∼2038 m2 g-1) and hydrophilic activated carbon cloth (ACC) as a current collector at the cathode. As anticipated, the SWB with ACC showed a reduced voltage gap (0.49 V), high energy efficiency (86%), improved rate capability, and improved power performance (16.2 mW cm-2) compared to those of the SWB operated with lower surface area carbon felt (2.2 m2 g-1, 1.24 V, 71%, and 5.5 mW cm-2, resp.). These findings suggest that hybridization of the EDL and OER/ORR processes on the cathode side of SWB can improve overall performance.

Yao, Yu published the artcileA Dual-Functional Conductive Framework Embedded with TiN-VN Heterostructures for Highly Efficient Polysulfide and Lithium Regulation toward Stable Li-S Full Batteries, SDS of cas: 143-24-8, the main research area is titanium nitride vanadium mononitride electrode lithium sulfur battery; Li dendrite; Li-S full battery; TiN-VN heterostructure; chemisorption; electrocatalysis.

Li-S (Li-S) batteries are strongly considered as next-generation energy storage systems because of their high energy d. However, the shuttling of Li polysulfides (LiPS), sluggish reaction kinetics, and uncontrollable Li-dendrite growth severely degrade the electrochem. performance of Li-S batteries. Herein, a dual-functional flexible free-standing C nanofiber conductive framework in situ embedded with TiN-VN heterostructures (TiN-VN@CNFs) as an advanced host simultaneously for both the S cathode (S/TiN-VN@CNFs) and the Li anode (Li/TiN-VN@CNFs) is designed. As cathode host, the TiN-VN@CNFs can offer synergistic function of phys. confinement, chem. anchoring, and superb electrocatalysis of LiPS redox reactions. Meanwhile, the well-designed host with excellent lithiophilic feature can realize homogeneous Li deposition for suppressing dendrite growth. Combined with these merits, the full battery (denoted as S/TiN-VN@CNFs || Li/TiN-VN@CNFs) exhibits remarkable electrochem. properties including high reversible capacity of 1110 mA-h g-1 after 100 cycles at 0.2 C and ultralong cycle life over 600 cycles at 2 C. Even with a high S loading of 5.6 mg cm-2, the full cell can achieve a high areal capacity of 5.5 mA-h cm-2 at 0.1 C. This work paves a new design from theor. and exptl. aspects for fabricating high-energy-d. flexible Li-S full batteries.

Subasinghe, Lihil Uthpala published the artcileA study on heat generation characteristics of Na3V2(PO4)3 cathode and hard carbon anode-based sodium-ion cells, Application In Synthesis of 143-24-8, the main research area is heat generation sodium vanadium phosphate cathode; hard carbon anode sodium ion cells.

We report here the heat generation and impedance characteristics of prototype 18650-sized sodium-ion cells using pristine Na3V2(PO4)3 (P-NVP) and modified Na3.2V1.8Zn0.2(PO4)3 (M-NVP) cathodes, hard carbon (HC) anode and an ether-based non-flammable electrolyte, 1 M NaBF4 in tetraglyme. Comparison of calorimetric studies performed on 18650-sized cells reveals lower heat generation in M-NVP vs. HC compared to P-NVP vs. HC owing to low internal resistance achieved as a result of Zn2+ doping in M-NVP. Both irreversible heat generation arose due to internal resistance and reversible heat generation caused by entropic changes in the electrode materials are elucidated. Furthermore, variation in subcomponents of internal resistance in both 18650-sized full cells and CR2016-sized half-cells is analyzed by fitting electrochem. impedance spectra into equivalent circuit models. Individual contributions of anode and cathode to the impedance characteristics of the cells are determined by analyzing impedance data of the half-cells using the distribution of relaxation times method. The results reveal lower diffusion resistance, as well as charge transfer resistance in M-NVP cells compared to P-NVP counterpart, accounting for the observed lower total internal resistance in M-NVP vs. HC and thus lower heat generation in M-NVP vs. HC cell than P-NVP vs. HC cell.

Li, Jiabao published the artcileTuning oxygen non-stoichiometric surface via defect engineering to promote the catalysis activity of Co3O4 in Li-O2 batteries, Computed Properties of 143-24-8, the main research area is oxygen vacancy electronic structure free standing electrode cobalt oxide; catalyst defect engineering lithium oxygen battery.

The performance of Li-O2 battery is governed by the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics. Adjusting the surface property of catalysts via defect engineering will inaugurate a new complexion on developing efficient oxygen electrodes. In this work, a novel strategy of creating rich oxygen vacancy in Co3O4 is developed via cerium incorporation. The oxygen vacancy in Ce-Co3O4 not only promotes charge migration due to the formation of unsaturated coordination sites where electrons become delocalized but also acts as active site to anchor O2 and Li2O2 thereby leading to synergic enhancement of ORR and OER kinetics. The low overpotential (0.9 V), large specific capacity (8250 mAh g-1) and extended cycling life of the Ce-Co3O4 based Li-O2 battery exptl. confirm its superior bifunctional catalytic activity. This relationship between surface properties and catalytic activity established by defect engineering can serve as an innovative strategy for guiding the further development of high performance electrode materials for Li-O2 batteries in the foreseeable future.
