Title:
CARBON NANOTUBE LIQUID DISPERSION, LAMINATE, PRODUCTION METHOD FOR CARBON NANOTUBE LIQUID DISPERSION, AND PRODUCTION METHOD FOR CARBON FILM
Document Type and Number:
WIPO Patent Application WO/2023/162937
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a carbon nanotube liquid dispersion that allows secondary battery electrodes to demonstrate a strong peel strength between an electrode mixture layer and a current collector formed from a metal, etc., and a weak peel strength for an electrode mixture layer provided with a release substrate made of a resin or the like, between the electrode mixture layer and the release substrate; and to allow a secondary battery to demonstrate superior rate performance, or realizes good film formation properties when a carbon film is formed. The carbon nanotube liquid dispersion according to the present invention contains carbon nanotubes and a solvent, wherein when a scattering curve obtained by the measurement conducted with ultra-small-angle X-ray scattering method is analyzed by the Beaucage model, the fractal dimension within a wavenumber range from 0.001 (1/Å) to 0.3 (1/Å) is in the range from 3 to 4.
