  • Patent number: 12244037
    Abstract: An electrode assembly manufacturing method includes the steps of: assembling an electrode stack; performing a primary heat press operation on the electrode stack; then performing a pre-heating operation on the electrode stack; and then performing a secondary heat press operation on the electrode stack. The pre-heating operation may include applying heat and pressure to the electrode stack for a time period from 10 seconds to 40 seconds under a pressure condition from 0.5 MPa to 2 MPa and under a temperature condition from 50° C. to 85° C. The pressure condition applied in the pre-heating operation may include applying a lower pressure than that applied in the primary and secondary heat press operations. The primary heat press operation may include engaging the electrode stack with a gripper to secure a position of the electrode stack, which gripper may be disengaged from the electrode stack before performing the pre-heating operation.

  • Publication number: 20250062493
    Abstract: An electrode assembly manufacturing method includes the steps of: assembling an electrode stack; performing a primary heat press operation on the electrode stack while engaging the electrode stack with a gripper; and then performing a secondary heat press operation on the electrode stack while the gripper is disengaged from the electrode stack. The secondary heat press operation may include applying heat and pressure to the electrode stack for a time period from 5 seconds to 60 seconds under a temperature condition from 50° C. to 90° C. and under a pressure condition from 1 Mpa to 6 Mpa. The step of assembling the electrode stack may include alternately stacking first and second electrodes on an elongated separator sheet, and sequentially folding the separator sheet over a previously-stacked one of the electrodes before a subsequent electrode is stacked. An apparatus for performing the manufacturing method is also disclosed.
