Abstract
A method of manufacturing a battery is disclosed. The method includes the steps of (A) suction-attaching the first separator to a winding core, (B) winding the first separator on the winding core, and (C) removing the wound electrode assembly from the winding core. The winding core includes a first group of holes and a second group of holes each formed in its outer circumferential surface. In step (A), suction is applied to the first separator through at least one of the first group of holes and the second group of holes, to suction-attach the first separator to the winding core. The first group of holes and the second group of holes are configured to be controllable so as to cause suction and gas discharge independently from each other.
Claims10
A method operatively associated with a winding machine for manufacturing a battery including a wound electrode assembly wherein a first separator, a negative electrode plate, a second separator, and a positive electrode plate are wound together, the method comprising steps of:
- suction-attaching the first separator to a winding core of the winding machine;
- winding the first separator onto the winding core;
- and
- removing a wound electrode assembly from the winding core, wherein:
- the winding core includes a first group of holes and a second group of holes each formed in an outer circumferential surface of the winding core;
- in the suction-attaching the first separator to the winding core, the suction is applied to the first separator through at least one of the first group of holes and the second group of holes, to suction-attach the first separator to the winding core;
- and
- controlling the suction gas discharge of the first group of holes and the second group of holes independently from each other by a controller of the winding machine.
