Claim 18:
19. A device for preparing a battery, comprising:
a first providing module configured to provide a first battery cell and a second battery cell, wherein a pressure relief mechanism of the first battery cell and a pressure relief mechanism of the second battery cell are arranged opposite to each other in a first direction;
a second providing module configured to provide a box body, wherein the box body accommodates the first battery cell and the second battery cell;
a third providing module configured to provide a partition component, wherein the partition component is configured to partition the first battery cell and the second battery cell in the first direction, the partition component includes a first wall and a second wall arranged opposite to each other, the first wall is provided with a first through hole, the second wall is provided with a second through hole, the first through hole is configured to guide emissions discharged from the pressure relief mechanism of the first battery cell, and the second through hole is configured to guide emissions discharged from the pressure relief mechanism of the second battery cell;
a fourth providing module configured to provide a first guard member, wherein the first guard member has a first weak portion;
a fifth providing module configured to provide a second guard member, wherein the second guard member has a second weak portion; and
an installing module configured to attach the first guard member to the first wall so that the first weak portion of the first guard member is arranged opposite to the first through hole, attach the second guard member to the second wall so that the second weak portion of the second guard member is arranged opposite to the second through hole, and install the partition component and the battery cells on the box body,
wherein in a cross section perpendicular to the first direction, the area of the first weak portion is greater than that of the first through hole, and the area of the second weak portion is greater than that of the second through hole.
