Manufacturing method of anode comprising lithium titanium oxide using the composition for anode comprising lithium titanium oxide

摘要

porous Li _{having an average particle size of the present invention 1~30, 4} Ti ₅ O ₁₂ cathode active material, the Li ₄ Ti ₅ O ₁₂ 2 to 20 parts by weight of the conductive material of the negative electrode active material 100 parts by weight, said Li ₄ Ti ₅ O ₁₂ cathode active material glycol of the hydrophobic compound from 0.1 to 10 parts by weight based on 100 parts by weight of the Li ₄ Ti ₅ O ₁₂ on 100 parts by weight of negative electrode active material About 2 to 20 parts by weight of the binder and the Li ₄ Ti ₅ O ₁₂ , including the negative electrode active material dispersion medium 100-1200 parts by weight per 100 parts by weight and, wherein the glycol of the hydrophobic compound is ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, polyethylene glycol and at least one material selected from polypropylene glycol, and the dispersion medium are ethanol, isopropyl alcohol, propanol, It relates to a process for the production of lithium-titanium oxide-based negative electrode using lithium titanium oxide for a negative electrode composition comprising the one or more materials selected from the butanol and water. According to the present invention, the electrode density is improved, and the negative electrode active material and the conductive material in the dispersion is enhanced, it is possible to inhibit the moisture absorption of the electrode itself, water absorption swelling battery or super capacitor is being suppressed swelling (swelling) developing This occurrence can be suppressed to improve the life characteristics. ;
