Abstract
Curved battery cell thickness measurement apparatuses and methods are provided, which are capable of accurately and consistently measuring the thickness of a curved battery cell obtained as the result of deformation of a cuboidal battery cell. The curved battery cell may be fixed perpendicular to a base using an arc-shaped jig that conforms to the shape of the curved battery cell, and the thickness of the curved battery cell is accurately and consistently measured using a low measurement pressure caliper at a fixed position.
Claims12
