METHOD OF FILLING ELECTROLYTE INTO BATTERY CELL

摘要

PURPOSE: A method for injecting electrolytes into a battery cell is provided to attain an automatic injection process that injects electrolytes into a battery and to enable a full charge of electrolytes in a battery using vacuum and pressure. CONSTITUTION: A method for injecting electrolytes into a battery cell comprises the steps of: positioning a battery(B) at a lower valve(V2); closing an upper valve(V1) and opening the lower valve to vacuumize the battery through a temporary storage part(30); storing electrolytes in the temporary storage part by opening the upper valve; applying pressure by closing the upper valve and opening the lower valve so that the electrolytes stored in the temporary storage part is filled in the battery; and degassing by releasing pressure.
