Battery, electric device, and manufacturing method and manufacturing device for battery

A manufacturing method for a battery, comprising:

• providing a box body, wherein the box body has a bottom wall;
• providing at least one box cover;
• providing at least one pressure release mechanism;
• providing at least one battery cell;
• installing the at least one pressure release mechanism on the bottom wall;
• installing the at least one battery cell inside the box body;
• and
• making the at least one box cover cover the box body, to make the at least one box cover and the box body arranged in a first direction and define together an accommodation space configured for accommodating the at least one battery cell,
• wherein projections of the at least one pressure release mechanism and the at least one battery cell do not overlap in a plane perpendicular to the first direction, and the at least one pressure release mechanism each is configured to be activated when a pressure or a temperature in the accommodation space reaches a threshold value, to release the pressure in the accommodation space.

A manufacturing device for a battery, comprising:

• a first providing device, configured for providing a box body, wherein the box body has a bottom wall;
• a second providing device, configured for providing at least one box cover;
• a third providing device, configured for providing at least one pressure release mechanism;
• a fourth providing device, configured for providing at least one battery cell;
• a first assembly device, configured for installing the at least one pressure release mechanism on the bottom wall;
• a second assembly device, configured for installing the at least one battery cell inside the box body;
• and
• a third assembly device, configured for making the at least one box cover cover the box body, to make the at least one box cover and the box body arranged in the first direction and define together an accommodation space configured for accommodating the at least one battery cell,
• wherein projections of the at least one pressure release mechanism and the at least one battery cell do not overlap in a plane perpendicular to the first direction, and the at least one pressure release mechanism each is configured to be activated when a pressure or a temperature in the accommodation space reaches a threshold value, to release the pressure in the accommodation space.
