  • Patent number: 12009548
    Abstract: A battery cell structure includes a first electrode assembly formed by winding a first electrode plate and a second electrode plate, and a second electrode assembly formed by winding a third electrode plate and a fourth electrode plate. The first electrode assembly includes a first lateral surface and a second lateral surface opposite to the first lateral surface. The second electrode assembly includes a third lateral surface disposed opposite to the first lateral surface of the first electrode assembly. The battery cell structure further includes a first tab electrically connected to the third electrode plate and a second tab electrically connected to the fourth electrode plate. Both the first tab and the second tab extend through the first lateral surface and the second lateral surface. The first tab is further electrically connected to the first electrode plate located on the second lateral surface of the first electrode assembly.

  • Publication number: 20230037967
    Abstract: A packaging structure including an accommodating part and a sealing part extending from the accommodating part. The accommodating part includes a first edge, a second edge, a third edge and a fourth edge which are connected in sequence. The first edge and the third edge are opposite to each other. The second edge and the fourth edge are both connected to the first edge and the third edge. The length of the first edge is less than the length of the second edge, and the length of the first edge is less than the length of the fourth edge. The sealing part includes a first sealing edge provided along the second edge, and a second sealing edge provided along the fourth edge. A part of the first sealing edge extending beyond the first edge and a part of the second sealing edge extending beyond the first edge are respectively folded towards the first edge.
