  • Catalyst including molecular sieve having topological pore structure, preparation method therefor and use thereof
    Patent number: 12246308
    Abstract: A catalyst contains a metal oxide, and a molecular sieve, in a crystal form, having a topological pore structure. The metal oxide is centrally distributed on the surface of the molecular sieve. Grains of the molecular sieve are exposed to at least three families of crystal planes. The family of crystal plane with the largest pore size in topology is occupied by the metal oxide by no more than 30%, preferably no more than 20%, or no more than 10%.

  • Double-vacuum four-cavity hermeticity detecting methods and machines for square housing batteries
    Patent number: 12130205
    Abstract: The present disclosure provides a double-vacuum four-cavity hermeticity detecting method and machine for a square housing battery. The method may include a loading device, four cavity devices, four cavity cover devices, four load transferring devices, two vacuum devices, a detecting device, and a discharging device, the cavity devices and the cavity cover devices may make a sealed cavity, and each of the vacuum devices predetermine two sealed cavities. While operating at the same time, four sealed cavities may be loaded for 8 s, vacuumed for 10 s and detected for a hermeticity for 5 s in a total of 15 s, and discharged for 8 s, a cycle time may be shortened to 8 s and a production period may be shortened to 32 s, and a productivity of a hermeticity detection may be improved to 15 PPM according to two batteries per cavity.
