Abstract
A battery cell manufacturing apparatus for forming a sealing surplus portion includes a cradle configured to fix and mount a battery cell; one or more induction heating coils formed by winding an electrical wire at least one time at a position corresponding to an outer periphery of a pouch type case to generate an induced current in the outer periphery on which the sealing surplus portion is to be formed; a power supply configured to supply an alternating current to the induction heating coils; and at least two pressing members configured to press both sides of the outer periphery on which the sealing surplus portion is to be formed, wherein the outer periphery is induction-heated by a magnetic field generated in the induction heating coils and up to a temperature at which heat fusion is possible to form the sealing surplus portion.
