BATTERY AND ELECTRIC DEVICE

A battery includes multiple battery groups and multiple straps. The multiple battery groups are arranged along a first direction, each battery group including multiple battery cells stacked along a second direction, the second direction intersecting the first direction. At least a portion of the strap is disposed on a side surface of at least one battery group along the first direction and configured to constrain the multiple battery cells of at least one battery group. At least two straps pass between adjacent battery groups and are configured to constrain the adjacent battery groups, the at least two straps not overlapping in the first direction and overlapping in a third direction, the third direction being perpendicular to the first direction and the second direction.
