Abstract: A cell includes a flat electrode assembly formed by superposing and winding respective first ends of a first electrode sheet, a first separator, a second electrode sheet, and a second separator. A first electrode tab is connected to the first electrode sheet, and a second electrode tab is connected to the second electrode sheet. The second electrode sheet includes a second current collector, a second outer membrane arranged on a surface facing away from a center of the cell, and a second inner membrane arranged on a surface facing the center of the cell. Respective starting ends of the second outer membrane and the second inner membrane are located on the second current collector between the first end of the second electrode sheet and a second bend. The second inner membrane is provided with an inner uncoated region at least at the second bend.

Abstract: The present application relates to the field of Li-ion batteries and, specifically, relates to a packaging housing for a Li-ion battery, a method for preparing the packaging housing for a Li-ion battery. A bare cell of the Li-ion battery is packaged by the packaging housing, the packaging housing comprises, successively from inside to outside, a sealing housing layer, a metal coating layer and a plastic coating layer; after the sealing housing layer packages the bare cell and then is sealed, the metal coating layer and the plastic coating layer are successively provided on an external surface of the sealing housing layer. Since each layer of the materials of the packaging housing is processed onto the external surface of the product during preparing or packaging process, the thickness and strength of folding edges and folding corners thereof are kept unchanged, packaging defects caused by the impact molding process are avoided.
