Abstract
An apparatus for manufacturing a battery cell to enhance the electrolyte wettability to an electrode assembly in the battery cell is provided. The apparatus includes a battery cell tray in which one or more preliminary battery cells are housed and an excitation unit which makes a contact opposite to contacting one side of the battery cell tray to apply megasonic vibration to the preliminary battery cell in a state in which the preliminary battery cell is housed. A method for manufacturing a battery cell using the apparatus is also provided.
Claims19
A battery cell manufacturing apparatus for enhancing the wetting of an electrolyte to an electrode assembly in a battery cell, the apparatus comprising:
- a battery cell tray configured to house at least one preliminary battery cell;
- and
- an excitation unit contacting one side of the battery cell tray to apply megasonic vibration to the at least one preliminary battery cell when the at least one preliminary battery cell is housed in the battery cell tray,
- wherein the megasonic vibration is a vibration having a frequency of 500 kHz to 3000 kHz.
