Zhang, Xiao-Ping published the artcileAnode interfacial layer formation via reductive ethyl detaching of organic iodide in lithium-oxygen batteries, COA of Formula: C10H22O5, the main research area is organic iodide ethyl detaching lithium oxygen battery.

As soluble catalysts, redox mediators can reduce the high charging overpotential of lithium-oxygen batteries by providing sufficient liquid-solid interface for lithium peroxide decomposition However, the redox mediators usually introduce undesirable reactions. In particular, the so-called “”shuttle effect”” leads to the loss of both the redox mediators and elec. energy efficiency. In this study, an organic compound, triethylsulfonium iodide, is found to act bifunctionally as both a redox mediator and a solid electrolyte interphase-forming agent for lithium-oxygen batteries. During charging, the organic iodide exhibits comparable lithium peroxide-oxidizing capability with inorganic iodides. Meanwhile, it in situ generates an interfacial layer on lithium anode via reductive Et detaching and the subsequent oxidation This layer prevents the lithium anode from reacting with the redox mediators and allows efficient lithium-ion transfer leading to dendrite-free lithium anode. Significantly improved cycling performance has been achieved by the bifunctional organic iodide redox mediator.

Moser, Maximilian published the artcileSide Chain Redistribution as a Strategy to Boost Organic Electrochemical Transistor Performance and Stability, Safety of 2,5,8,11-Tetraoxatridecan-13-ol, the main research area is organic electrochem transistor performance stability polythiophene side chain redistribution; bioelectronics; ethylene-glycol-functionalized polymers; mixed ionic-electronic conduction; organic electrochemical transistors.

A series of glycolated polythiophenes for use in organic electrochem. transistors (OECTs) is designed and synthesized, differing in the distribution of their ethylene glycol chains that are tethered to the conjugated backbone. While side chain redistribution does not have a significant impact on the optoelectronic properties of the polymers, this mol. engineering strategy strongly impacts the water uptake achieved in the polymers. By careful optimization of the water uptake in the polymer films, OECTs with unprecedented steady-state performances in terms of [μC*] and current retentions up to 98% over 700 electrochem. switching cycles are developed.

Cronau, Marvin published the artcileThickness-Dependent Impedance of Composite Battery Electrodes Containing Ionic Liquid-Based Electrolytes, COA of Formula: C10H22O5, the main research area is lithium ion battery thickness charge transfer resistance current density.

Lithium-ion battery models often neglect the salt concentration polarization inside the electrolyte-filled pores of the composite electrodes. However, this concentration polarization causes a significant impedance, in particular in the case of electrolytes with low Li+ transference numbers Here, we analyze in detail measured and calculated impedance spectra of composite electrodes containing a solvate ionic liquid-based electrolyte and an ionic liquid-based electrolyte, resp., in comparison to a conventional carbonate-based electrolyte. For calculating spectra, we use a recently published model by Huang and Zhang. We find that the impedance at 10-4 Hz, which is relevant for battery cycling rates around 1 C to 2 C, increases in the order carbonate-based electrolyteCOA of Formula: C10H22O5.

Kim, Yeongsu published the artcileSynergistic nanoarchitecture of mesoporous carbon and carbon nanotubes for lithium-oxygen batteries, Name: 2,5,8,11,14-Pentaoxapentadecane, the main research area is mesoporous carbon lithium oxygen battery elec conductivity; Carbon nanotube; Electrochemistry; Lithium–oxygen battery; Mesoporous carbon.

A rechargeable lithium-oxygen battery (LOB) operates via the electrochem. formation and decomposition of solid-state Li2O2 on the cathode. The rational design of the cathode nanoarchitectures is thus required to realize high-energy-d. and long-cycling LOBs. Here, we propose a cathode nanoarchitecture for LOBs, which is composed of mesoporous carbon (MPC) integrated with carbon nanotubes (CNTs). The proposed design has the advantages of the two components. MPC provides sufficient active sites for the electrochem. reactions and free space for Li2O2storage, while CNT forests serve as conductive pathways for electron and offer addnl. reaction sites. Results show that the synergistic architecture of MPC and CNTs leads to improvements in the capacity ( ~18,400 mAh g- 1), rate capability, and cyclability (~200 cycles) of the CNT-integrated MPC cathode in comparison with MPC.

Zhang, Yi-Peng published the artcileA porous framework infiltrating Li-O2 battery: a low-resistance and high-safety system, Application In Synthesis of 143-24-8, the main research area is lithium oxygen battery porous framework infiltrating.

Li-O2 batteries, which have attracted great attention because of their high energy d., suffer from issues such as flammability of organic liquid electrolytes, corrosion of the Li anode and the shuttling effect of redox mediators. Using inorganic solid-state electrolytes (SSEs) can solve such issues. But high resistance at the SSE-electrode interfaces in these batteries hinders their further development. In this study, a “”porous framework infiltrating (PFI)”” concept is proposed. The framework is created on the surface of a garnet Li6.4La3Zr1.4Ta0.6O12 (LLZTO) ceramic by acid etching. After infiltrating a tiny amount of liquid electrolyte, this framework exhibits nonflammability and is thus ideal for high-safety applications. Moreover, the porous structure increases the contact area between the SSE and cathode, which can lower the interfacial resistance and improve the rate capability. Utilizing a Li-Sn alloy anode, the PFI Li-O2 battery exhibits smooth charging platforms with different rates, a prolonged cycle life and a promising round-trip efficiency. Therefore, the PFI structure provides a new strategy to build safe and high-performance Li-O2 batteries.

Ue, Makoto published the artcileMaterial balance in the O2 electrode of Li-O2 cells with a porous carbon electrode and TEGDME-based electrolytes, COA of Formula: C10H22O5, the main research area is O2electrode porous carbon electrode TEGDME electrolyte.

This work figures out the material balance of the reactions occurring in the O electrode of a Li-O cell, where a Ketjenblack-based porous carbon electrode comes into contact with a tetraethylene glycol di-Me ether (TEGDME)-based electrolyte under more practical conditions of less electrolyte amount and high areal capacity. The ratio of electrolyte weight to cell capacity (E/C, g A h) is a good parameter to correlate with cycle life. Only 5 cycles were obtained at an areal capacity of 4 mA h cm (E/C = 10) and a discharge/charge c.d. of 0.4 mA cm, which corresponds to the energy d. of 170 W h kg at a complete cell level. When the areal capacity was decreased to half (E/C = 20) by setting a c.d. at 0.2 mA cm, the cycle life was extended to 18 cycles. However, the total elec. charge consumed for parasitic reactions was 35 and 59% at the first and the third cycle, resp. This surprisingly large amount of parasitic reactions was suppressed by half using redox mediators at 0.4 mA cm while keeping a similar cycle life. Based on byproduct distribution, we will propose possible mechanisms of TEGDME decomposition and report a water breathing behavior, where HO is produced during charge and consumed during discharge.

Atchimnaidu, Siriki published the artcilePhototheranostic DNA micelles from the self-assembly of DNA-BODIPY amphiphiles for the thermal ablation of cancer cells, Product Details of C9H20O5, the main research area is phototheranostic DNA micelle BODIPY amphiphile cancer cell thermal ablation.

Design of phototheranostic agents in a single step approach is one of the challenges in cancer therapy. Herein, a one-step strategy based on amphiphilicity-driven self-assembly of DNA-BODIPY amphiphiles for the design of a new class of micelles, which offer all three phototheranostic functions, is reported. These include (i) strong emission at NIR (ϕf = 30%) for imaging, (ii) high photothermal conversion (η = 52%) for PTT and (iii) an ssDNA-based shell for the integration of cell targeting moieties. Selective uptake of DNA micelles into a target cancer cell and its killing by laser irradiation (635 nm) are also demonstrated. Furthermore, the excellent biocompatibility, ultrasmall nanosize and high stability of DNA micelles are promising for in vivo applications.

Sultana, Fozia published the artcileAn innovative approach towards the simultaneous enhancement of the oxygen reduction and evolution reactions using a redox mediator in polymer based Li-O2 batteries, Recommanded Product: 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium oxygen battery cathode redox mediator polymer electrolyte.

For safety concerns, polymer-based Li-O2 batteries have received more attention than traditional non-aqueous Li-O2 batteries. However, poor cycling stability, low round trip efficiency, and over charge potential during cycling are the major shortcomings for their future applications. In this work, a soluble redox mediator integrated into a polymer electrolyte provides immediate access to the solid discharged product, lowering the energy barrier for reversible Li2O2 generation and disintegration. Moreover, introducing a redox mediator to the polymer electrolyte boosts the ORR during discharge and the OER during the recharge process. The synergistic redox mediator pBQ (1,4-benzoquinone) dramatically reduces the over-potential. A small proportion of pBQ in the polymer electrolyte allows Li2O2 to develop in a thin film-like morphol. on the cathode surface, resulting in a high reversible capacity of ∼12 000 mA h g-1 and an extended cycling stability of 100 cycles at 200 mA g-1 with a cut-off capacity of 1000 mA h g-1. The remarkable cell performance is attributed to the fast kinetics of para-benzoquinone for the ORR and OER in Li-O2 batteries. The use of a redox mediator in a polymer electrolyte opens a new avenue for practical Li-O2 battery applications in achieving low charge potential and excellent energy efficiency.

Kottam, P. K. R. published the artcileEffect of salt concentration, solvent donor number and coordination structure on the variation of the Li/Li+ potential in aprotic electrolytes, Application of 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium electrolyte salt concentration solvent donor number.

The use of concentrated aprotic electrolytes in lithium batteries provides numerous potential applications, including the use of high-voltage cathodes and Li-metal anodes. In this paper, we aim at understanding the effect of salt concentration on the variation of the Li/Li+ Quasi-Reference Electrode (QRE) potential in Tetraglyme (TG)-based electrolytes. Comparing the obtained results to those achieved using DMSO DMSO-based electrolytes, we are now able to take a step forward and understand how the effect of solvent coordination and its donor number (DN) is attributed to the Li-QRE potential shift. Using a revised Nernst equation, the alteration of the Li redox potential with salt concentration was determined accurately. It is found that, in TG, the Li-QRE shift follows a different trend than in DMSO owing to the lower DN and expected shorter lifespan of the solvated cation complex.
