Title:
NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY POSITIVE ELECTRODE SLURRY PRODUCTION METHOD AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY POSITIVE ELECTRODE SLURRY
Document Type and Number:
WIPO Patent Application WO/2017/138193
Kind Code:
A1
Abstract:
In order to provide a production method for a non-aqueous electrolyte secondary battery positive electrode slurry, such that surplus carbon dioxide gas can be reliably degassed after an alkali component in a slurry including an alkali metal complex oxide has been neutralized in a short time, this production method for a non-aqueous electrolyte secondary battery positive electrode slurry including an alkali metal complex oxide includes an electrode slurry production step comprising: a step in which an inorganic carbon mixed in a slurry solvent is used and the alkali component of the slurry is neutralized, said inorganic carbon mixed in the slurry solvent being generated by a carbon dioxide gas being dissolved in the slurry solvent, and the pressure of the carbon dioxide gas being 0.12-100 MPa; and a step in which the inorganic carbon in the slurry is degassed as carbon dioxide gas by agitating the neutralized slurry.
