Title:
ELECTROCONDUCTIVE PIGMENT PASTE, MIX PASTE, AND ELECTRODE FOR LITHIUM-ION BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/063003
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an electroconductive pigment paste and a mix paste which, even when having a high pigment concentration, are excellent in terms of pigment dispersibility and storage stability, and of providing an electrode for lithium-ion batteries which has various excellent performances. The electroconductive pigment paste comprises a pigment-dispersing resin (A), an electroconductive pigment (B), a solvent (C), a fluororesin (D), and a basic low-molecular-weight component (E), wherein the pigment-dispersing resin (A) has at least one kind of polar functional groups and has a concentration of the polar functional groups of 0.3-23 mmol/g, the electroconductive pigment (B) includes carbon nanotubes (B1), and when the content of the basic low-molecular-weight component (E) per 100 parts by mass of the content of the carbon nanotubes (B1) is expressed by α (parts by mass) and the BET specific surface area of the carbon nanotubes (B1) is expressed by β (m2/g), then X=α/β×300 and the X is 5 or greater.
