Abstract

This invention relates to a powder containing carbon nanotubes (CNTs) for electrodes, comprising carbon nanotubes (CNTs) and a modified polyvinyl alcohol resin with an acetal structure as a dispersant. In the aforementioned powder containing CNTs for electrodes, the dispersant can adhere to the surface of the CNTs. In the aforementioned powder containing CNTs for electrodes, the weight ratio of the CNTs to the dispersant (CNT:dispersant) can be 33:67 to 99:1.
