シリコン系負極における「シリコン」はどこから来るのか？
In recent years, the rapid development of new energy vehicles has raised higher demands for battery performance. Traditional graphite-based anode materials have low specific capacity and are difficult to meet the demand. Silicon has an extremely high theoretical specific capacity, which can effectively improve battery performance. It has great potential for development as an anode material. The silicon source material, particle morphology, and processing methods significantly impact the performance of silicon-based negative electrodes. Let’s take a look at the silicon sources of silicon-based negative electrodes. Diatomite, Zeolite, sand and Other Mineral Silicon Sources Mineral silicon is the most abundant and widely distributed silicon source today. It mainly exists in the […]

Polypropylene (PP) is a widely used thermoplastic polymer, known for its easy processing and excellent properties. This makes it essential in industries such as packaging, home appliances, and automotive parts. Despite its widespread use, PP has certain limitations. These include high thermal shrinkage, poor performance in low temperatures, and inadequate impact resistance. These shortcomings have driven the development of strategies to enhance PP’s properties. One effective method is the incorporation of various mineral powders for polypropylene modification, enhancing its overall performance. By adding inorganic mineral powders, such as calcium carbonate, talc, and mica, the thermal stability of PP can be improved. This also enhances its impact strength and overall performance. […]

希土類研磨粉：見過ごされてきた金
Cerium-based rare earth polishing powder is the most popular rare earth polishing powder. It has excellent polishing performance, improving surface smoothness. It is known as the “king of polishing powders.” The glass processing and electronics industries are the main downstream applications. About 70% of polishing powder waste is from polishing failure each year. The waste mainly consists of rare earth powder residues, waste liquids, glass fragments, and polishing cloth residues. The rare earth content in the waste is around 50%. Handling the waste rare earth polishing powder has become a major challenge for downstream companies. Currently, the common methods for recycling waste rare earth polishing powder are physical separation and […]
