  • Manufacturing method for secondary battery and manufacturing apparatus for secondary battery
    Patent number: 11217867
    Abstract: A manufacturing method for a secondary battery and a manufacturing apparatus for a secondary battery that are applicable to a secondary battery in which an electrolyte solution injection hole has a diameter of 1.5 mm or more are provided. The secondary battery includes a battery case including a cover plate provided with an electrolyte solution injection hole, and a sealing member sealing the electrolyte solution injection hole. The manufacturing method includes a preparing step and a press-fitting step. The preparing step is preparing a cell in which, after an electrolyte solution is injected to the battery case through the electrolyte solution injection hole, the sealing member is disposed on the electrolyte solution injection hole. The press-fitting step is press-fitting the sealing member into the electrolyte solution injection hole while applying press-fitting load and ultrasonic vibration with a frequency of 20 kHz or more in parallel to a press-fitting direction.
