Abstract

A button battery is provided in the application, and includes a positive electrode case, a negative electrode case and a sealing sleeve. The positive electrode case includes a support portion and a corner portion connected to an outer side of the support portion. The corner portion includes a first turning segment having a first curvature radius R1 and a second turning segment having a second curvature radius R2. The second turning segment is connected between the support portion and the first turning segment. The negative electrode case includes a covering portion and a bending snap-engage portion having a third curvature radius R3. The covering portion and the support portion are disposed oppositely. The sealing sleeve is sandwiched between the corner portion and the bending snap-engage portion, so as to enable sealing between the positive electrode case and the negative electrode case.
