Abstract
Official abstract text for this publication.
The method of the present disclosure for producing an electrode active material slurry includes kneading a raw material mixture in a kneading device, wherein the kneading device has a heating portion for heating the lowermost portion of the raw material mixture and a cooling portion for cooling the uppermost portion of the raw material mixture, and during the kneading, the temperature of the heating portion is 5° C. or higher than the temperature of the cooling portion.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of producing electrode active material slurry, the method comprising kneading a raw material mixture in a kneading device, wherein: the kneading device includes a heating unit that heats a lowermost portion of the raw material mixture, and a cooling unit that cools an uppermost portion of the raw material mixture; and during the kneading, a temperature of the heating unit is 5° C. or more higher than a temperature of the cooling unit. 2 . The method according to claim 1 , wherein during the kneading, a temperature of the lowermost portion of the raw material mixture is 5° C. or more higher than a temperature of the uppermost portion of the raw material mixture. 3 . The method according to claim 1 , wherein the raw material mixture has a viscosity of 90,000 mPa·s or more. 4 . A method of manufacturing a secondary battery, the method comprising: producing electrode active material slurry by the method according to claim 1 ; and applying and drying the electrode active material slurry to form an electrode active material layer.
