Document Type and Number:
WIPO Patent Application WO/2020/062295
Kind Code:
A1
Abstract:
A lithium cell, a smart battery, and a method for manufacturing a lithium cell. The lithium cell comprises: a support (20) formed in a plate shape; a cell assembly (10) wound on the support (20), such that the support (20) is wrapped in the cell assembly (10), the cell assembly (10) comprising at least one negative electrode (12), at least one positive electrode (11), and a separator membrane (13) enabling an arrangement in which the positive electrode (11) and the negative electrode (12) are spaced apart; a housing (50) having an accommodating cavity for accommodating the support (20) and the cell assembly (10); and an electrolyte, filled in the cell assembly (10) and/or a space between the housing (50) and the cell assembly (10), wherein the support (20) supports the cell assembly (10) and has two opposing surfaces adhered to the cell assembly (10), such that the cell assembly (10) is adhered to the support (20) to prevent relative movements therebetween and form an integrated body. The cell assembly (10) is wound around and adhered to the support (20), and the support (20) provides support to the cell assembly (10) so as to maintain structural stability of the cell assembly (10).
