Nishino, Haruka published the artcileIonic transport and mechanical properties of slide-ring gel swollen with Mg-ion electrolytes, Application In Synthesis of 143-24-8, the main research area is slide ring gel electrolyte swelling ionic transport mech property.

The authors applied a slide-ring (SR) gel to a Mg2+ ion gel electrolyte and clarified the elec. and mech. properties in order to achieve a Mg2+ ion gel electrolyte with both sufficient mech. strength and high ionic conductivity The SR gel is made from polyrotaxane, which has a structure that consists of cyclic mols., α-cyclodextrins (CDs), threaded by an axial polymer chain, polyethylene glycol (PEG), and crosslinked by divinyl sulfone. Pure glymes and tetraethylene glycol di-Me ether (tetraglyme: G4) dissolving Mg2+ ions had no ability to swell the SR gel, whereas diethylene glycol di-Me ether (diglyme: G2) and triethylene glycol di-Me ether (triglyme: G3) dissolving Mg2+ ions were able to swell the SR gel. The swelling behavior was strongly dependent on the interaction between Mg2+ ions complexed with glymes and ether oxygens of a PEG-based hydroxypropyl PR (HyPR) network. Upon tensile elongation, SR gel swollen with G3 solution dissolving Mg2+ ions could be extended by 300%, which indicated the unique property of high ductility. The ionic conductivity of SR gel swollen with G3 dissolving Mg2+ ions, which approx. satisfied a Vogel-Tamman-Fulcher (VTF) dependence, was 1.73 mS cm-1 at room temperature, and the molar conductivity was 67% of that for a pristine G3 solution dissolving Mg2+ ions.

Delnick, Frank M. published the artcileInvestigation of Complex Intermediates in Solvent-Mediated Synthesis of Thiophosphate Solid-State Electrolytes, Category: ethers-buliding-blocks, the main research area is solvent mediated synthesis thiophosphate solid state electrolyte.

Lithium thiophosphates represent a promising class of solid Li+ conductors for all-solid-state batteries. Scalable solvent-mediated synthesis routes for several Li-P-S ternary compounds have been reported, but little is known regarding the reaction mechanism of such pathways. This work demonstrates that solvent-mediated synthesis of lithium thiophosphate solid electrolytes from mixtures of Li2S and P2S5 proceeds through a highly soluble P2S62- intermediate. This intermediate exhibits virtually the same Raman spectra in several solvents including acetonitrile, Me acetate, Et acetate, Et propionate, dimethoxyethane, tetraethylene glycol di-Me ether, and THF. Based on this universal intermediate, a general reaction mechanism is proposed for the solvent-mediated synthesis of several lithium thiophosphates including (LiPS3)n, Li2P2S6, Li7P3S11, and Li3PS4.

Yang, Lanlan published the artcileHybrid MgCl2/AlCl3/Mg(TFSI)2 Electrolytes in DME Enabling High-Rate Rechargeable Mg Batteries, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is magnesium battery cathode electrolyte aluminum chloride magnesium TFSI; DME electrolyte; conductivity; rechargeable magnesium batteries; volumetric energy.

Rechargeable magnesium batteries (RMBs) are considered as one of the most promising next-generation secondary batteries due to their low cost, safety, dendrite-free nature, as well as high volumetric energy d. However, the lack of suitable cathode material and electrolyte is the greatest challenge facing practical RMBs. Herein, a hybrid electrolyte MgCl2/AlCl3/Mg(TFSI)2 (MACT) in di-Me ether (DME) is developed and exhibits excellent electrochem. performance. The high ionic conductivity (6.82 mS cm-1) and unique solvation structure of [Mg2(μ-Cl)2(DME)4]2+ promote the fast Mg kinetics and favorable thermodn. in hybrid Mg salts and DME electrolyte, accelerating mass transport and the charge transfer process. Therefore, the great rate capability can be realized both in sym. Mg/Mg cell and in CuS/Mg full cell.

Zou, Changfei published the artcileIn Situ Formed Protective Layer: Toward a More Stable Interface between the Lithium Metal Anode and Li6PS5Cl Solid Electrolyte, Name: 2,5,8,11,14-Pentaoxapentadecane, the main research area is lithium metal battery anode solid electrolyte interface ionic liquid.

Due to the advantages of high safety and high energy d., solid-state lithium batteries (SSLBs) are promising competitors for next-generation batteries. Unfortunately, the growth of Li dendrites and irreversible capacity loss caused by the Li metal anode/solid electrolyte interfacial incompatibility remain challenges. Herein, an in situ formed artificial protective layer between the lithium metal anode and solid electrolyte Li6PS5Cl (LPSC) is introduced. A stable solid electrolyte interface (SEI) is in situ formed in the Li/Li6PS5Cl interface via the electrochem. reduction of the liquid electrolyte LiTFSI/tetraethylene glycol di-Me ether (Li(G4)TFSI), which is beneficial for the improvement of the stability of interfacial chem. and homogeneous lithium deposition behavior. The assembled Li/Li(G4)TFSI-assisted Li6PS5Cl/Li sym. cells enable stable cycles for 850 and 400 h at a c.d. of 0.1 and 0.2 mA/cm2, resp. Moreover, the LiNi0.6Co0.1Mn0.3O2(NCM613)/Li(G4)TFSI-assisted Li6PS5Cl/Li SSLBs can achieve prominent cycling stability at room temperature This work provides a new insight into the interfacial modification to design SSLBs with high energy d.

Cheng, Eric Jianfeng published the artcileEffects of porosity and ionic liquid impregnation on ionic conductivity of garnet-based flexible sheet electrolytes, Computed Properties of 143-24-8, the main research area is porosity ionic liquid impregnation conductivity garnet flexible sheet electrolyte; aluminum doped lithium lanthanum zirconium oxide battery solid electrolyte.

Although the garnet-type ceramic ionic conductor, Li7La3Zr2O12 (LLZO), shows relatively high chem. stability against Li metal and has the potential to replace flammable liquid electrolytes for Li metal batteries, the large interfacial resistance between LLZO and electrodes challenges its practical application. A possible solution is to produce a quasi-solid-state LLZO-based flexible sheet electrolyte. Here we prepared an Al-doped LLZO-based flexible sheet electrolyte and studied its ionic conductivity as functions of porosity and ionic liquid (IL) impregnation. Possible Li+ ion conducting pathways through the quasi-solid-state composite sheet electrolyte were discussed and its electrochem. performance was also evaluated.

Lee, Dawoon published the artcileMulti-Foldable and Environmentally-Stable All-Solid-State Supercapacitor Based on Hierarchical Nano-Canyon Structured Ionic-Gel Polymer Electrolyte, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is ionic gel polymer electrolyte solid state supercapacitor.

New ionic-gel polymer electrolytes (IGPEs) are designed for use as electrolytes for all-solid-state supercapacitors (ASSSs) with excellent deformability and stability. The combination of the photochem. reaction-based polymer matrix, weak-binding lithium salt with ionic liquid, and ion dissociating solvator is employed to construct the nano-canyon structured IGPE with high ionic conductivity (σDC = 1.2 mS cm-1 at 25°C), high dielec. constant (εs = 131), and even high mech. robustness (bending deformation for 10 000 cycles with superior conductivity retention [≈91%]). This gives rise to ASSS with high compatibility and stability, which is compliant with foldable electronics. Consequently, this ASSS delivers remarkable electrochem. performance (specific capacitance of ≈105 F g-1 at 0.22 A g-1, maximum energy d. and power d. of 23 and 17.2 kW kg-1), long lifetime (≈93% retention after 30 days), wider operating temperature (≈0-120°C), and mech. stabilities with no significant capacitance reduction after mech. bending and multiple folding, confirming the superior electrochem. durability under serious deformation states. Therefore, this ultra-flexible and environmentally stable ASSS based on the IGPE having the nano-canyon morphol. can be a novel approach for powering up the ultra-deformable and durable next-generation wearable energy storage devices.

Bhatt, Pinakin J. published the artcileEffect of Different Cations on Ion-Transport Behavior in Polymer Gel Electrolytes Intended for Application in Flexible Electrochemical Devices, Name: 2,5,8,11,14-Pentaoxapentadecane, the main research area is tetraethylene glycol dimethyl ether polymer gel electrolyte electrochem device.

This paper reports the effect of different cations (Na, Mg and Li) while keeping perchlorate as the common anion on ion-dynamics behavior within polymer gel electrolytes containing tetraethylene glycol di-Me ether (TEGDME) solvent and poly(vinylidene fluoride-hexafluoropropylene) (PVdF-HFP) as the polymer host. FTIR investigations demonstrate significant changes in characteristic bands, while XRD observations indicate prominent structural variation in terms of merger/suppression of phases when NaClO4, Mg(ClO4)2 and LiClO4 salts are immobilized in the PVdF-HFP/TEGDME matrix. The highest room temperature ionic conductivity of 1.2 x 10-3 S cm-1 with high dielec. constant value has been obtained for the Li+ conducting electrolyte composition due to its superior electrochem. and ion-conduction behavior as compared to its Na+ and Mg2+ counterparts. In the low-frequency region, modulus curves reveal polarizing effects with long-range mobility/migration of Na/Mg/Li ions, while in the high-frequency region, a peak onset relating the translational ion dynamics and conductivity relaxation is observed The reported polymer gel electrolytes may be employed as electronic materials for developing next-generation flexible electrochem. devices.

He, Xin published the artcileInsights into the Ionic Conduction Mechanism of Quasi-Solid Polymer Electrolytes through Multispectral Characterization, Computed Properties of 143-24-8, the main research area is quasi solid polymer electrolyte ionic conduction mechanism multispectral characterization; ion transport mechanism; polyvinylidene fluoride-hexafluoropropylene; quasi-solid polymer electrolyte; spectroscopic characterization.

Quasi-solid polymer electrolytes (QPE) composed of Li salts, polymer matrix, and solvent, are beneficial for improving the security and energy d. of batteries. However, the ionic conduction mechanism, existential form of solvent mols., and interactions between different components of QPE remain unclear. Here we develop a multispectral characterization strategy combined with first-principles calculations to unravel aforesaid mysteries. The results indicate that the existential state of solvent in QPE is quite different from that in liquid electrolyte. The Li cations in gel polymer electrolyte are fully solvated by partial solvent mols. to form a local high concentration of Li+, while the other solvent mols. are fastened by polymer matrix in QPE. As a result, the solvation structure and conduction mechanism of Li+ are similar to those in high-concentrated liquid electrolyte. This work provides a new insight into the ionic conduction mechanism of QPE and will promote its application for safe and high-energy batteries.

Han, Fengfeng published the artcileV2CTX catalyzes polysulfide conversion to enhance the redox kinetics of Li-S batteries, Safety of 2,5,8,11,14-Pentaoxapentadecane, the main research area is vanadium carbide polysulfide conversion redox kinetics lithium sulfur battery.

Lithium-sulfur (Li-S) batteries have the potential to become the future energy storage system, yet they are plagued by sluggish redox kinetics. Therefore, enhancing the redox kinetics of polysulfides is key for the development of high-energy d. and long-life Li-S batteries. Herein, a Ketjen Black (KB)/V2CTX modified separator (KB/V2CTX-PP) based on the catalytic effect in continuous solid-to-liquid-to-solid reactions is proposed to accelerate the conversion of sulfur species during the charge/discharge process in which the V2CTX can enhance the redox kinetics and inhibit polysulfide shuttling. The cells assembled with KB/V2CTX-PP achieve a gratifying first discharge capacity of 1236.1 mA h g-1 at 0.2C and the average capacity decay per cycle reaches 0.049% within 1000 cycles at 1C. The work provides an efficient idea to accelerate redox conversion and suppress shuttle effects by designing a multifunctional catalytic separator.

Alzate-Carvajal, Natalia published the artcileA comparative study on the influence of the polymeric host for the operation of all-solid-state batteries at different temperatures, COA of Formula: C10H22O5, the main research area is polymer electrolyte solid state battery temperature.

Solid Polymer Electrolytes (SPE) are critical components to develop safe, high energy d. all solid-state lithium metal batteries (ASSB), providing favorable mech. properties and good stability vs Li-metal. Typically used poly(ethylene oxide) (PEO) based electrolytes do not allow cycling of all solid-state cells at room temperature due to the crystallization of PEO hindering the ionic transport. Increasing the ionic conductivity of SPE at lower temperature is then mandatory. This study addresses the challenge thanks to the use of Polymerized ionic liquid (PIL), poly(diallyldimethylammonium) bis(trifluoromethanesulfonyl)imide (PDADMAT) as polymeric host for producing SPE. Mixtures of PDADMAT and PEO with tetraglyme Li salt IL, LiG4TFSI, are prepared and their electrochem. properties in lithium metal batteries investigated. Through composition optimization, membranes containing 66 wt % of LiG4TFSI were selected as the best compromise in term of conduction properties (above 10-4 S/cm at room temperature), transference number of ca. 0.4 and mech. behavior. All-solid-state cells prepared using PDADMAT-based membranes were able to cycle at 60 °C and room temperature up to 0.425 mA/cm2 current densities whereas POE-based cells could only sustain 60 °C cycling. The study underlines the benefit of using IL and PIL as components of SPE for the operation of high performance ASSB at room temperature
