Abstract (en)
[origin: WO2022038047A1] A method (10) for producing an electrode of a battery cell is provided, wherein, in a first mixing step (102), a first fraction of carbon nanotubes and an active electrode material are mixed together in a mixer at a first rotational speed to form a first mixture. Furthermore, in a second mixing step (104), a second fraction of carbon nanotubes (206) and the first mixture are mixed together in the mixer at a second rotational speed to form a second mixture, wherein the first rotational speed is greater than the second rotational speed.
