NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY POSITIVE ELECTRODE SLURRY PRODUCTION METHOD AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY POSITIVE ELECTRODE SLURRY

WIPO Patent Application WO/2017/138192

A1

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 dissolved into a slurry solvent is used and the alkali component of the slurry is neutralized; and a step in which the inorganic carbon in the slurry is degassed as carbon dioxide gas, by generating cavitation.
