摘要
The present invention relates to a process for producing a cathode foil of a lithium-containing battery, comprising: (i) provision of a dry, solvent-free composition which comprises polytetrafluoroethylene, an electrically conductive, electrochemically inactive carbon material and an electrochemically active cathode material, (ii) formation of at least partially fibrillated polytetrafluoroethylene by action of shear forces on the dry, solvent-free composition to give a fibrillated composition, (iii) forming of the fibrillated composition to give a cathode foil.
