The battery cell is formed by winding a first electrode sheet and a second electrode sheet; the first electrode sheet and the second electrode sheet are separated by a separator; a head portion of the second electrode sheet is provided with an empty foil area which is not coated with an active substance; the empty foil area is provided with a first protection adhesive paper and second protection adhesive paper; the first protection adhesive paper and the second protection adhesive paper are located on two sides of an edge of a head portion of the first electrode sheet in a thickness direction of the battery cell.

Abstract: An electrode plate includes a current collector and an active material layer, the current collector includes a first segment, a first segment, and a first coating area, a second coating area and a slot area are distributed on at least one side of the first segment; the second coating area includes a transition area, and along a width direction of the current collector, the transition area is located between the slot area and an edge of the current collector; and the active material layer is attached to a surface of the current collector in the first coating area and the second coating area, and a thickness of the active material layer in the second coating area is less than that of the active material layer in the first coating area. Therefore, technical problems of easy breakage of an electrode plate are solved.

Abstract: A lithium battery includes a wound core and tabs, in which the wound core is formed by stacking and winding an inner separator, a first electrode sheet, an outer separator, and a second electrode sheet; the inner separator is located at the innermost layer of the wound core, and each of the inner separator and the outer separator has a clamping section, a first straight section, and a tail laminating section, where the first straight section is located in front of the first electrode sheet, and the clamping section, the first straight section and the tail laminating section of the inner separator are respectively laminated with the clamping section, the first straight section and the tail laminating section of the outer separator; and a dry peeling force of each of the first straight sections of the inner separator and the outer separator is less than 8 N/m.

Abstract: The application discloses a lithium-ion cell, a battery and a power device, which belongs to the technical field of lithium-ion battery structure. A side surface of an end portion of a cell body of the lithium-ion cell has a thin area relative to a middle portion of the cell body, and the lithium-ion cell further includes adhesive paper attached to the thin area. In this application, a special adhesive paper is designed and attached to the thin area formed due to thinning processing at the edge of the end portion of the lithium-ion cell body, and is suitable for compensating for the thin area of the lithium-ion cell, so that the cell has a flat surface, is stressed uniformly during hot-pressing formation and has a good bonding.

Abstract: A building automation and control network (BACnet) master-slave/token-passing (MS/TP) automatic media access control (MAC) addressing system having a BACnet MS/TP network, a MAC assigner on the network, and one or more MAC assignees on the network. Each assignee may have a global unique identity (GUID) and the assigner may have a pre-defined address. The assigner may gather virtually all GUIDs of the MAC assignees on the network and gather virtually all unused MAC addresses on the network. The assigner may map GUIDs to the unused MAC addresses and send a resulting map to the MAC assignees for assignment of a MAC address to each assignee. Each assignee may be assigned a MAC address according to its GUID, and the assignment of a MAC address to each assignee may occur automatically without manual intervention. In other words, the system may provide auto MAC addressing.
