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.
