Abstract
A method for producing a positive electrode containing a positive electrode active material and/or a negative electrode containing a negative electrode active material. The method includes a process for producing an electrode slurry including: a first process in which a positive or negative electrode active material, a conductive additive, and a nonaqueous solvent are mixed to obtain a slurry; and a second process in which the slurry is diluted or concentrated and then mixed to obtain the electrode slurry. In the first process, the mixing is performed such that the obtained slurry has a water content of 1000 ppm or less and a viscosity of 500 cP or more and 8000 cP or less, and, in the second process, the mixing is performed such that a water content of the obtained electrode slurry is maintained at the water content of the slurry after the first process is completed.
