| titleOfInvention | Method for producing carboxymethyl cellulose salt for electrode of nonaqueous electrolyte secondary battery, electrode for nonaqueous electrolyte secondary battery, and nonaqueous electrolyte secondary battery |
| abstract | The object of the present invention is to provide a carboxymethylcellulose salt for an electrode of a non-aqueous electrolyte secondary battery, which can prevent defects such as streaks and pinholes on the coated surface of the electrode and can combine excellent adhesion to a current collector Strength or adhesive strength between active substances. A production method comprising the following steps: (1) an alkali cellulose reaction step, which uses a mixed solvent with a mixing ratio (mass ratio) of alcohol with a carbon number of 3 or less and water of 75:25 to 95:5, and The concentration of alkali relative to water is 25% to 40% by mass; (2) etherification reaction step, which is carried out under the excess of alkali, and the excess of alkali is 0.2 mole per anhydroglucose unit of the cellulose ~0.5 moles; (3) neutralization step, after the etherification reaction is finished, adding acid to adjust the pH value of the reaction mixture to 6.0 ~ 8.0; and (4) heating step, after the neutralization step is finished , removing the mixed solvent, adding a base to adjust the pH of the reaction mixture to 8.0-9.0, and then performing heat treatment at 40°C-70°C for 30 minutes-120 minutes. |
