Broyage ultrafin du graphite : comment permet-il la création de la prochaine génération de batteries à haute densité énergétique ?
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. […]
Comment sont produits les matériaux de cathode en phosphate de fer lithié ?
Cathode materials, one of the four main materials in lithium batteries (cathode, anode, separator, and electrolyte), are crucial components of lithium batteries. They also account for a large portion of the battery’s cost. The cost of cathode materials largely determines the price of the battery. Among lithium battery cathode materials, mainstream materials include lithium cobalt […]
Le broyage par jet d'air peut-il résoudre le problème persistant d'agglomération dans la production de molybdate d'ammonium ?
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 […]
Quelles sont les trois principales méthodes de préparation de la poudre de titanate de baryum ?
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 […]
Comment préparer du charbon poreux à partir de charbon actif ?
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 […]

Why Ceramic-Lined Pulverizing Equipment Is Essential in the Production of New Energy Cathode and Anode Materials
In the lithium-ion battery industry, the ultra-fine grinding and classification of cathode and anode materials are key processes that directly determine material performance. Whether it is high-nickel cathode (NCM/NCA), lithium iron phosphate (LFP), artificial graphite, soft carbon, or hard carbon, powder quality strongly affects battery energy density, rate capability, and cycle life. As battery performance […]
Comment le broyeur à jet d'air affecte-t-il la distribution granulométrique et les caractéristiques morphologiques des matériaux d'anode en carbone dur ?
The practical performance of hard carbon anode materials in sodium-ion batteries is highly dependent on their microstructure, and the particle size distribution (PSD) and morphology are key factors determining ion diffusion pathways, electrode packing density, first-cycle Coulombic efficiency, and cycle stability. Air jet mill, as the most commonly used ultrafine grinding method in hard carbon […]
Comment la poudre de talc est-elle appliquée dans les revêtements ?
Talc powder is one of the most widely used and cost-effective functional fillers in the coatings industry. Its main component is hydrated magnesium silicate, with the chemical formula 3MgO·4SiO₂·H₂O, belonging to the monoclinic crystal system. It typically appears as pseudo-hexagonal or rhombohedral plate-like crystals. High-quality talc powder is white or off-white. It has a smooth, […]
