Transition metal fluoride (TMF) conversion-type cathodes promise up to 4 times higher gravimetric energy densities compared those of common intercalation-type cathodes. However, TMF demonstrate sluggish kinetics, poor efficiencies, and incompatibility with many liquid electrolytes. In this work, coevaporated heterostructured iron lithium (Fe-LiF) are investigated in thin-film solid-state batteries a LiPON electrolyte anode. The cells were cycled 2000 at cycling rate 6C. They show gradual...
Li-ion batteries have a pivotal role in the transition toward electric transportation. Ni-rich layered metal oxide (LTMO) cathode materials promise high specific capacity and lower cost but exhibit faster degradation compared with Ni alternatives. Here, we employ high-resolution electron microscopy spectroscopy techniques to investigate nanoscale origins impact on performance of intragranular cracking (within primary crystals) LTMOs. We find that is widespread charged specimens early cycle...
Tailored electrochemical protocols and characterisation methods provide a detailed account of degradation mechanisms in high energy lithium-ion batteries with nickel-rich cathodes.
In the concept of anode-free lithium-ion batteries, cells are manufactured with a bare anode current collector where lithium metal is electrochemically formed from lithium-containing cathode during first charge cycle. While this has many attractive aspects manufacturing and energy density standpoint, stable plating stripping remain challenging. We have investigated gold, platinum, amorphous carbon as seed layers placed between copper phosphorus oxynitride thin-film solid electrolyte. These...
IL@MOF (IL: ionic liquid; MOF: metal-organic framework) materials have been proposed as a candidate for solid-state electrolytes, combining the inherent non-flammability and high thermal chemical stability of liquid with host-guest interactions MOF. In this work, we compare structure conductivity sodium ion containing composite formed from microcrystalline powder zeolitic imidazolate framework (ZIF), ZIF-8 hierarchically porous sample both micro- mesopores sol-gel synthesis. Although...
Solution-processing has been a very successful fabrication route for Cu2ZnSn(S, Se)4 (CZTSSe) absorbers: since 2010, every world record CZTSSe-based solar cells achieved by this approach. The solution...
This review article delves into the growing field of solid-state batteries as a compelling alternative to conventional lithium-ion batteries. The surveys ongoing research efforts at renowned Swiss institutions such ETH Zurich, Empa, Paul Scherrer Institute, and Berner Fachhochschule covering various aspects, from fundamental understanding battery interfaces practical issues fabrication, their design, production. then outlines prospects batteries, emphasizing imperative challenges that remain...
Li- and Mn-rich layered oxides (Li1.2Ni0.2Mn0.6O2) are actively pursued as high energy sustainable alternatives to the current Li-ion battery cathodes that contain Co. However, severe decay in discharge voltage observed these needs be addressed before they can find commercial applications. A few mechanisms differing origin have been proposed explain fade, which may caused by differences material composition, morphology electrochemical testing protocols. Here, challenges synthesising...
pyXem 0.10.0 is the Q3 2019 minor release of pyXem, an open-source Python library for crystallographic diffraction. In this cycle we have added a significant amount new functionality to code, as summarized below. The API prior from v0.9.x has changed very minimally. Details all development associated with are available here. HyperSpy Extension & Lazy Signal Classes pyxem now registers hyperspy extension on installation. This means that and Component classes recognised by LazyDiffraction1D,...
Abstract In order to find a relationship between structural and electrical properties, niobium yttrium doped SrTiO3 ceramics were prepared via solid-state reaction. The samples sintered in hydrogen air conditions. also fabricated with pore-former obtain highly porous specimens. properties of Nb-doped co-doped compared. comparable observed discussed according previous literature reports. It was noticed that the synthesis reducing atmosphere can increase solubility dopants. Moreover, presented...
Abstract Operando electrochemical transmission electron microscopy (ec‐TEM) is a promising tool for advanced characterization of energy systems close to their operating conditions. However, reliable sample preparation the technique particularly challenging due spatial constraints.
