Abstract: The disclosure relates to the technical field of batteries and provides a cylindrical battery including a winding cell. One end of the winding cell is provided with a first tab and a center of the winding cell is formed with a central hole. The first tab includes a first tab layer and a second tab layer disposed adjacent to each other, the first tab layer includes a first single tab, the second tab layer includes at least two second single tabs, a number of the second single tabs of the second tab layer is one more than a number of the first single tab of the first tab layer.

Abstract: The disclosure relates to the technical field of batteries and provides a cylindrical battery including a winding cell. The winding cell includes a winding cell body and a first tab extending from one side of the winding cell body. The winding cell body is wound to form a central hole. In a radial direction of the central hole, the first tab includes a plurality of single tabs, and the plurality of single tabs form a first region. Herein, heights of the plurality of single tabs in the first region gradually increase. A difference value between a maximum height difference value and a minimum height difference value between adjacent single tabs in the radial direction of the central hole is less than or equal to 0.5 mm. The height of each of the single tabs is a dimension of the single tab in a lead-out direction thereof.

Abstract: The disclosure relates to the technical field of batteries, and a cylindrical battery is provided, including a wound core, and the wound core includes: a wound core body; a first tab portion, which extends from one side of the wound core body, the wound core body is formed with a wound core hole, the first tab portion includes a first tab set and a second tab set adjacent to each other, the first tab set includes at least two first tabs, and the second tab set includes a second tab; a first gap is formed between adjacent first tabs, and the orthographic projections of the second tab and the first gap on the same plane at least partially overlap each other along the radial direction of the wound core hole.

Abstract: The disclosure relates to the technical field of batteries, and a cylindrical battery is provided, including: a single cell housing structure; a core, which is arranged in the single cell housing structure, and the core includes a core body, a first tab and a second tab, and the first tab and the second tab arranged at intervals extend out from the same end of the core body, and the core body is formed with a winding center; the first tab and the second tab are arranged along the circumferential direction of the winding center, and the length of the first tab is greater than the length of the second tab along the radial direction of the winding center. A certain distance may be set between the first tab and the second tab on basis that the first tab and the second tab are able to have sufficient current-passing capability.

Abstract: The disclosure relates to the technical field of batteries, and a battery is provided, including a housing; a cell, which is disposed in the housing, and includes a main body and a first tab, and the first tab is led out from one end of the main body; a first insulator, which is disposed in the housing; a first current collector, which is integrally formed in the first insulator, and is connected to the first tab; the largest circumferential outer edge of the orthographic projection of the first current collector facing an end surface of the main body is located inside the largest circumferential outer edge of the orthographic projection of the first insulator facing an end surface of the main body.

Abstract: A cylindrical battery includes a battery housing; a cell, which is arranged in the battery housing, and includes a cell body and a tab portion, and the tab portion is extended from at least one side of the cell body; a first insulating film, which is arranged on the outer surface of the cell body, and is connected with the cell; a second insulating film, which is arranged on the outer surface of the cell body, the second insulating film covers and is connected with the first insulating film. One end of the second insulating film is not lower than an end surface of the cell body provided with the tab portion, and the other end of the second insulating film overlaps the first insulating film so that a portion of the second insulating film overlaps the first insulating film.

Abstract: Disclosed are a GITR-targeting antibody, a preparation method therefor and the use thereof. In particular, disclosed is a novel GITR-targeting chimeric antibody or a fully humanized monoclonal antibody. Also disclosed is a method for preparing the monoclonal antibody. The monoclonal antibody of the present invention can bind to a GITR antigen with a high specificity, and has a very high affinity and a significant anti-tumor activity or the like.
