Abstract
Provided is a method for manufacturing a slurry for a positive electrode of a nonaqueous electrolyte secondary battery containing an alkali metal complex oxide, the method making it possible to reliably deaerate surplus carbonic acid gas after an alkali component of a slurry containing the alkali metal complex oxide is neutralized within a short period of time. The method for manufacturing a slurry for a positive electrode of a nonaqueous electrolyte secondary battery includes a step of manufacturing an electrode slurry including a step of performing a neutralization treatment on an alkali component in the slurry by using inorganic carbon dissolved in a solvent of the slurry and a step of deaerating the inorganic carbon in the slurry as carbonic acid gas by causing cavitation.
