PRE-DISPERSION SOLUTION, ELECTRODE COMPOSITION, ELECTRODE SLURRY, ELECTRODE, AND LITHIUM-ION SECONDARY BATTERY

Disclosed is a pre-dispersion solution including single-walled carbon nanotubes (SWCNTs), in which with respect to 100 parts by weight of the entire single-walled carbon nanotubes, the content of single-walled carbon nanotubes having a length of more than 0 μm and less than 0.2 μm is more than 0 parts by weight and 1 part by weight or less, and the content of single-walled carbon nanotubes having a length of 10 μm or more and less than 100 μm is 15 parts by weight or more, and an electrode composition, an electrode slurry, an electrode, and a lithium ion secondary battery which include the same. Since the dispersibility of the pre-dispersion solutions is controlled, the pre-dispersion solution may contribute to the improvement in the phase stability of electrode compositions and/or electrode slurries and the stability, service life, safety, and the like of electrodes and/or lithium ion secondary batteries, in the future.
