Provided is a method for producing a copper complex ink which has excellent storage stability and with which copper wiring having low volume resistivity and high smoothness can be produced. The method for producing a copper complex ink containing a copper complex represented by general formula (HCOO)2Cu((CH3)2C(NH2)CH2OH)2 includes an agitation step for agitating a mixture of powder of Cu(HCOO)2·4H2O and a solid or liquid of (CH3)2C(NH2)CH2OH by a thin-film spin method, wherein the molar ratio of Cu(HCOO)2·4H2O to (CH3)2C(NH2)CH2OH in the mixture is 1:1.8 to 2.2.

There is provided a slurry composition for a negative electrode of a secondary battery suitable for producing a battery such as a lithium ion battery and an electrode, which has high stability and is capable of forming a negative electrode having a low resistance value when formed into an electrode, even when the slurry composition for a negative electrode of a secondary battery uses carbon nanotubes. A slurry composition for a negative electrode of a secondary battery according to the present disclosure includes at least carbon nanotubes, a conductive material, a negative electrode active material, a dispersant, and a binder component. The dispersant includes carboxymethylcellulose having a mass average molecular weight of 300000 or less or a metal salt thereof, and carboxymethylcellulose having a mass average molecular weight of 1000000 to 3000000 or a metal salt thereof.

The present invention relates to a ligand exchange technique for III-V group colloidal quantum dots. By employing a ligand surface treatment method, the invention facilitates the ligand exchange process in III-V group quantum dots while enhancing their solvent dispersibility. Furthermore, by substituting heterogeneous ligands, the invention enables the production of quantum dot ink based on environmentally friendly solvents and its application in device fabrication. Accordingly, the present invention proposes III-V group colloidal quantum dots incorporating heterogeneous ligands, a method for manufacturing environmentally friendly solvent-based quantum dot ink, and an optoelectronic device utilizing the ink.
