  • Publication number: 20240106039
    Abstract: A battery cell includes a housing, an electrode assembly accommodated in the housing, and an end cover configured to buckle to an opening of the housing. The end cover comprises a first body part, a first end wall, and a first peripheral wall. The first body part is configured to be connected to the housing. The first end wall is farther away from the electrode assembly than the first body part. The first peripheral wall is disposed around an edge of the first end wall and connected to the first body part, and the first peripheral wall and the first end wall jointly form a first accommodation space used to accommodate at least a part of a tab of the electrode assembly. The first peripheral wall comprises a first arc wall extending from the first end wall to the first body part along a first arc trajectory.

  • Publication number: 20210299322
    Abstract: Provided is a device that uses ozone, hydrogen peroxide, and hydroxyl radicals to sterilize, detoxify and purify indoor air, while simultaneously removing radon gas. The device is provided with a condensing unit (10) having a Peltier structure, and further provided with a device (2) that discharges electricity and generates ozone. The device further has an ultraviolet lamp (9) and a titanium dioxide coating for creating a titanium dioxide physical environment. The device is also provided with generation boxes (3, 5). Ultrasonic waves are used to electrolyze a liquid, such as water, hydrogen peroxide or oxygen, in the generation boxes (3, 5), so as to further generate hydroxyl radicals.
