    摘要： A notching mold for molding a non-coated portion of an electrode base material, wherein the non-coated portion, is formed on each of two ends of a coated portion, includes: a main mold having an upper mold and a lower mold, parallel to each other, and are slidable close to or away from each other. A first auxiliary mold having auxiliary upper and lower molds coupled to the upper and lower molds, respectively, is configured so that the non-coated portion on one end of the electrode base material is disposed at a processible position. A second auxiliary mold having auxiliary upper and lower molds coupled to the upper and lower molds, respectively, is configured so that, when the electrode base material is input into the main mold, the non-coated portion on the other end of the electrode base material is disposed at a processible position.

    摘要： 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.

    摘要： An electrode assembly includes a plurality of electrodes arranged in a stack along a stacking axis with a respective separator portion of an elongated separator sheet positioned between and winding around each of the electrodes in the stack along a serpentine path. An intermediate one of the separator portions may be adhered to an intermediate one of the electrodes such that it would take a peel force in a range from 5 gf to 35 gf per 20 mm width applied to an edge of the intermediate separator portion in order to peel it away from the intermediate electrode at a speed of 100 mm/min along the stacking axis. Moreover, top and bottom ones of the separator portions may each have a value of air permeability from 70 sec/100 ml to sec/100 ml per square inch of the respective separator portion at a pressure of 0.05 MPa and at room temperature.

    摘要： An electrode assembly includes a plurality of electrodes arranged in a stack along a stacking axis with a respective separator portion of an elongated separator sheet positioned between and winding around each of the electrodes in the stack along a serpentine path. The plurality of electrodes include a top electrode positioned at a top of the stack along the stacking axis, and the plurality of electrodes include a bottom electrode positioned at a bottom of the stack. The separator portions in the stack include a top separator portion abutting the top electrode and a bottom separator portion abutting the bottom electrode. The top separator portion and the bottom separator portion each have a value of air permeability from 80 sec/100 ml to 120 sec/100 ml per square inch of the respective separator portion at a pressure of 0.05 MPa and at room temperature.
