Original Abstract Submitted
a battery includes: a box including an electrical chamber; a battery cell accommodated in the electrical chamber, where a pressure relief mechanism is disposed at a first wall of the battery cell; and an attachment structure attached to the first wall, where the attachment structure is provided with an avoidance region. the avoidance region is configured to provide a deformation space for the pressure relief mechanism of at least one battery cell, and the avoidance region satisfies 0.3≤s/(n*s)≤8.5, where s represents a projection area of the pressure relief mechanism in a direction perpendicular to the first wall, s represents a projection area of the avoidance region in the direction perpendicular to the first wall, n represents the number of pressure relief mechanisms corresponding to the avoidance region, and n is a positive integer.
