METHOD FOR MANUFACTURING A LITHIUM ION POLYMER BATTERY, BATTERY CELL, AND LITHIUM ION POLYMER CELL COMPRISING SAME

摘要

The present invention relates to a method for manufacturing a lithium ion polymer battery, which involves injecting an electrolyte into the lithium ion polymer battery by enabling a battery cell to be submerged in an electrolytic bath such that the inside of the battery cell can be impregnated with the electrolyte. According to the present invention, the impregnation with the electrolyte is performed all at once, and the electrolyte stays within the battery cell after activation, thereby preventing the electrolyte from adhering to a sealing portion (i.e., electrolyte-adhering sealing) during the sealing of the battery cell.
