Abstract
A process for the production of a lithium polymer cell is involves extruding a material mixture for an anode and a mixture for a cathode to form an anode and cathode masses. At least one of the masses is extruded with a mixture of cyclohexanone and methyl ethyl ketone. The anode and cathode masses are laminated onto conductors and joined with an intervening separator to form a lithium polymer cell.
Claims20
A process for the production of a lithium polymer cell comprising:
- providing a material mixture for an anode mass and a material mixture for a cathode mass;
- separately extruding the anode material mixture and the cathode material mixture to form an anode mass and a cathode mass, at least one of the material mixtures containing a mixture of cyclohexanone and methyl ethyl ketone;
- laminating the anode mass onto a first conductor and laminating the cathode mass onto a second conductor, to form an anode and a cathode, respectively;
- removing the cyclohexanone and methyl ethyl ketone from the anode, the cathode, or both;
- and
- joining of the anode and the cathode with a separator disposed therebetween to form a lithium polymer cell.
