Researchers have been working for many years to find new material and cell systems that can be used as potential post-lithium-ion batteries. Among these, the all-solid-state battery is considered a promising candidate, with sulfide-based materials having essential advantages over other solid electrolyte materials, particularly in terms of their high ionic conductivity. A great challenge, however, reactivity contact water, where harmful hydrogen sulfide (H2S) formed. Since H2S formation has...
Impedance measurements are a powerful tool to investigate interfaces in lithium-ion batteries (LIBs). In order deconvolute the anode and cathode contributions cell impedance, reference electrode (RE) is required. However, there only very few reports on use of three-electrode setup with an RE for all-solid-state (ASSBs), which due complexity integrating suitable geometry into typical ASSB test cells that based compressed electrolyte pellet. this study, we present straightforward approach...
A key for the market penetration of large-scale and high energy All-Solid-State Batteries (ASSBs) are sheet-type cell components. Herein, we report a slurry-based process to obtain free-standing solid electrolyte (SE)/binder composite sheets as ASSB separators. We investigate three different sulfidic systems (Li 6 PS 5 Cl, Li 7 P 3 S 11 10 SnP 2 12 ) in combination with hydrogenated nitrile butadiene rubber (HNBR). By means electrochemical impedance spectroscopy (EIS), influence separator...
Mono-pivaloyloxyzinc acetylide and bis-pivaloyloxyzinc were selectively prepared from ethynylmagnesium bromide in quantitative yields. These zinc reagents readily underwent Negishi cross-couplings with (hetero)aryl iodides or bromides as well subsequent Sonogashira cross-couplings. 1,3-Dipolar cycloadditions of these acetylides benzylic azides produced zincated bis-zincated triazoles which trapped several electrophiles. An opposite regioselectivity compared to the Cu-catalyzed...
A major hurdle for the wide spread commercialization of proton exchange membrane based fuel cells (PEMFCs) and water electrolyzers are durability high cost noble metal catalysts. Here, alternative support materials might offer advantages, as they can alter properties a catalyst by means strong interaction (SMSI) that has been shown to prevent platinum oxidation suppress oxygen reduction reaction on titanium oxide supported nanoparticles deposited carbon (Pt/TiO x /C). Herein, we report novel...
The demand for batteries with high gravimetric and volumetric energy density is driving research towards the development of new battery technologies. All-solid-state (ASSBs) offer potential to address current challenges faced by liquid electrolyte-based batteries, such as implementation Li-metal or fully utilized silicon an anode material. 1 To date, however, there are no commercially available ASSBs inorganic solid electrolyte on market, because when using electrolytes, interfacial...
All-Solid-State Batteries (ASSBs) have emerged as a highly promising post-lithium-ion battery technology, offering notable advancements in safety and energy density. However, an intrinsic disadvantage arises from the usually higher density of inorganic solid electrolyte materials compared to their liquid counterparts, constituting drawback that hinders gains overall To overcome this limitation, imperative is transition towards specific capacity materials, thereby unlocking full potential for...
Electrifying the automotive sector requires energy storage systems with high and power density, intrinsic safety, long durability.

In order to enable the market introduction of all-solid-state batteries (ASSBs), several anode concepts are under investigation increase energy density compared graphite anodes, while maintaining long cycle-life. At same time, production costs must be or even reduced in comparison with classical lithium-ion batteries. Besides lithium metal as material, which still poses significant technical challenges, more and interest is being directed toward materials that form alloys. One most...
All-solid-state batteries (ASSBs) are widely investigated in the field of lithium-ion battery (LIB) research, since they might offer several advantages over conventional LIB technology based on liquid electrolytes, for example a possible lower flammability solid electrolytes compared to organic solvents LIBs.
