1. an electric core winding method is characterized in that, may further comprise the steps:

  • The first step, pole piece and barrier film are got the raw materials ready;

    positive plate, negative plate and barrier film are prepared into continuous coiled strip, and are installed in respectively on positive plate feed mechanism, negative plate feed mechanism and the barrier film feed mechanism;

    Second step, the heating of positive plate and negative plate;

    start positive plate heating arrangements, negative plate heating arrangements, heating cathode sheet and negative plate;

    In the 3rd step, reel;

    positive/negative plate after will heating and barrier film are wound into electric core, during coiling, and the pulling force that the pulling force that positive plate and negative plate receive receives greater than barrier film;

    The 4th step, cooling;

    go on foot gained electricity core natural cooling at room temperature with the 3rd.
