Battery cell structure of button battery and munufactuturn merhod thereof, and button battery

A battery cell structure of a button battery, comprising a winding core (10) which is formed by winding a laminated structure and is provided with a hollow inner hole (14), wherein the winding core (10) is provided with a first tab (20) and a second tab (30), the laminated structure comprises at least one positive electrode sheet (11), at least one negative plate (12), and a separator (13) which separates the at least one positive electrode sheet (11) from the at least one negative electrode sheet (12), characterized in that, at least two ends of the winding core (10) are provided with a separator bonding layer (132) wrapping the winding core (10), and the separator bonding layer (132) is configured to fix a positive electrode sheet (11) and a negative electrode sheet (12),

• wherein when the first tab (20) is located at an outer ring of the winding core (10), the separator (13) is disposed at an outer side of the positive electrode sheet (11) or the negative electrode sheet (12) connected to the first tab (20);
• the separator bonding layer (132) comprises a first separator bonding layer located at an inner side of the first tab (20) and a second separator bonding layer located at an outer side of the first tab (20), and a bonding force of the first separator bonding layer is greater than that of the second separator bonding layer.
