Anode pre-dispersion solution, anode composition comprising same, anode for lithium secondary battery comprising anode composition, lithium secondary battery comprising anode, and method for preparing anode composition

Abstract

A negative electrode pre-dispersion solution, a negative electrode composition comprising the same, a negative electrode for a lithium secondary battery comprising a negative electrode composition, a lithium secondary battery comprising a negative electrode, and a preparation method of a negative electrode composition are disclosed. A negative electrode pre-dispersion solution, including a pre-dispersion material containing carbon nanotubes and a dispersant; and a dispersion medium. The dispersant includes carboxyl groups as a functional group. A solid content of the pre-dispersion material is 5% or less based on the negative electrode pre-dispersion solution, and 20 parts by weight or more and 60 parts by weight or less of the carbon nanotubes; and 40 parts by weight or more and 80 parts by weight or less of the dispersant are present based on 100 parts by weight of the pre-dispersion material.
