Abstract
The invention relates to a dispersion comprising a dispersion medium, a polymeric dispersing agent, and carbon nanotubes dispersed in the dispersion medium. The proportion of carbon nanotubes present in the form of agglomerates with an average agglomerate size of >=1 [mu]m to the total quantity of carbon nanotubes <=10 vol %, and >=70% of the carbon nanotubes which are not present in the agglomerated form have a length of >=200 nm. the invention further relates to a method for producing such a dispersion, to a method for producing an electrode with the dispersion, to an electrode obtained in this manner, and to an electrochemical element containing the electrode.
