Warum sind Silizium-Kohlenstoff-Anoden der Schlüssel zu Lithium-Ionen-Batterien der nächsten Generation mit hoher Energiedichte?
Silicon–carbon (Si–C) anodes materials are regarded as one of the core enabling technologies for next-generation high-energy-density lithium-ion batteries. They are designed to overcome the intrinsic limitation of conventional graphite anodes, whose theoretical specific capacity is only 372 mAh/g, and to enable a major leap in battery energy density. I. Why Choose Silicon? Why Must It […]
Wie ist der Entwicklungsstand von ultrafeinen, nichtmetallischen Mineralpulvern?
Ultrafine powders refer to a class of materials with particle sizes ranging from the micrometer to the nanometer scale. At present, the extensive application of non-metallic mineral powders in modern high-tech new materials is based on their unique functional properties. The functional performance of most non-metallic minerals is highly dependent on particle size, particle size […]
Welche Herstellungsverfahren gibt es für ultrafeine Pulver?
In recent years, new material development has accelerated worldwide. Materials research is moving toward extreme states and higher performance. Among emerging materials, ultrafine powders have attracted significant attention. Current research on ultrafine powders mainly focuses on four aspects: preparation methods, microstructure, macroscopic properties, and applications. Among these, preparation technology is the most critical factor. There […]
Wie steigert die Ultrafeinvermahlung den industriellen Mehrwert von Baryt?
Barite (mainly composed of BaSO₄) is an important non-metallic mineral resource. Barite is characterized by its high specific gravity (4.2–4.6), strong chemical inertness, acid and alkali resistance, and non-toxicity. Traditionally, about 80–90% of barite is used as a weighting agent in oil and gas drilling fluids. The remaining portion is applied as a chemical raw […]
Wie lassen sich die Probleme “Übermahlung” und “Agglomeration” bei der Pulverherstellung mit einem Windsichter lösen?
In powder production—especially in the preparation of ultrafine powders—overgrinding and agglomeration are two common challenges. Overgrinding refers to a situation in which qualified fine particles continue to be ground. This leads to energy waste, a broader particle size distribution, and, in some cases, degraded product performance. Agglomeration occurs when ultrafine particles attract each other through […]
Graphit-Ultrafeinvermahlung: Wie ermöglicht sie die nächste Generation von Hochenergiebatterien?
Graphite is one of the most classical members of the carbon family. It has long dominated lithium-ion battery anode materials. This is due to its excellent thermal conductivity and electrical conductivity. Graphite also offers high-temperature resistance and lubricating properties. It has been listed as a critical raw material by the EU and the United States. […]
Kann das Strahlmahlen das hartnäckige Agglomerationsproblem bei der Ammoniummolybdat-Produktion lösen?
Ammonium molybdate (mainly including ammonium dimolybdate, ammonium tetramolybdate, and ammonium heptamolybdate) is an important intermediate in molybdenum deep processing. It is widely used in the production of molybdenum powder, molybdenum trioxide, catalysts, molybdenum metal products, and agricultural molybdenum fertilizers. During ammonium molybdate production, agglomeration has long been a persistent challenge for the industry. This problem […]
Welche drei Hauptmethoden zur Herstellung von Bariumtitanatpulver gibt es?
Barium titanate (BaTiO₃) powder is the primary raw material of titanate-based electronic ceramics. As a typical ferroelectric material with excellent dielectric properties, it is widely used in multilayer ceramic capacitors (MLCCs), sonar devices, infrared radiation detectors, grain-boundary ceramic capacitors, and positive temperature coefficient (PTC) thermistors. With broad application prospects, barium titanate is regarded as a […]
Wie stellt man porösen Kohlenstoff aus Aktivkohle her?
Activated carbon is itself a typical porous carbon material. It features a highly developed pore structure, a large specific surface area, and excellent adsorption performance. It is widely used in adsorption, catalyst supports, and energy storage. Porous carbon is a broader concept that includes carbon materials with micro-, meso-, and macropores. In particular, hierarchical porous […]
