The garnet-type Li7La3Zr2O12 (LLZO) ceramic solid electrolyte combines high Li-ion conductivity at room temperature with chemical stability. Several all-solid-state Li batteries featuring the LLZO and LiCoO2 (LCO) or LiCoO2-LLZO composite cathode were demonstrated. However, all exhibit rapid capacity fading during cycling, which is often attributed to formation of cracks due volume expansion contraction LCO. Excluding possibility mechanical failure crack between LiCoO2/LLZO interface, a...
Spark plasma sintering as the prominent field‐assisted technique (FAST/SPS) is a novel technology for rapid, pressure‐assisted consolidation of powder materials. The main feature FAST/SPS direct Joule heating applied tooling. Tooling challenging part setup, which must withstand high pressure at elevated temperatures and ensure uniform temperature distribution in sintered part. This review looks standard tooling, specific tooling complex‐shaped parts, pressureless sintering. A particular...
AbstractThe production of highly porous titanium parts complex shape by powder metallurgical technology is described. Well defined porosity and pore sizes were achieved using a forming additive. This additive also enhances the strength unsintered compacts, allowing machining in green state. The requirements initial powders pecularities each step are discussed detail. microstructure materials examples net given, aiming preferentially at biomedical applications. impurities obtained compared...
Highly efficient energy conversion and storage technologies such as high‐temperature solid oxide fuel electrolysis cells, all‐solid‐state batteries, gas separation membranes, thermal barrier coatings for advanced turbine systems depend on materials. In all cases, processing of ceramics metals starting from powders plays a key role is often challenging task. Depending their composition, powder materials require high sintering temperatures show an inherent risk abnormal grain growth,...
All-solid-state lithium batteries are promising candidates for next-generation energy storage systems. Their performance critically depends on the capacity and cycling stability of cathodic layer. Cells with a garnet Li7La3Zr2O12 (LLZO) electrolyte can show high areal capacity. However, they commonly suffer from degradation during cycling. For fully inorganic cells based LiCoO2 (LCO) as cathode active material LLZO, electrochemically induced interface amorphization has been identified an...
AbstractAbstractThe production route of highly porous near net shape titanium parts includes the green machining compacts made metallic and pore former (often ammonium bicarbonate) powder mixtures. Success in greatly depends on compact strength. The aim present work was to determine quantitatively evaluate factors influencing strength titanium–ammonium bicarbonate compacts. substantial dependence amount compaction pressure demonstrated. Some influence particle size also observed. A...
In present paper the Equal Channel Angular Extrusion (ECAE) through a rectangular die was firstly physically simulated using plasticine and then theoretically analyzed by upper bound method. Physical simulation used to identify deformation zone as background for following theoretical ECAE analysis rigid block model. The plane strain mode ideal plasticity of an extruded material were assumed. dependencies pressure, accumulated shear dimension "dead zone" upon friction factor analytically...
Polymer–ceramic all-solid-state Li batteries (ASSLBs) combine the advantages of fully inorganic and polymer-based ASSLBs. In particular, application proposed polymer–ceramic composite cathodes could be essential for enhancement energy storage capacity The use a modified field-assisted sintering technique with adjustable pressure alternative mica foil enables fabrication porous at reduced temperature without side phase formation. This allows LiCoO2/Li7La3Zr2O12:Ta network suitable polymer...
Titanium foams are regarded as potent materials for biomedical applications such bone implants, and are, if possible, manufactured close to their final shape by sintering processes. There cases, however, in which it is necessary generate the machining, problems resulting from porous structure material characteristics become critical. In this article, two important methods of i.e. face milling peripheral grinding, investigated applicability Ti foams, scope limitations discussed.
