Abstract

Disclosed are methods of manufacturing positive electrode slurries for all-solid-state batteries, and positive electrodes manufactured using the methods. The method includes preparing a first mixture including a positive electrode active material and a solid electrolyte, adding a binder solution to the first mixture to perform a first kneading process on a second mixture having a solid content adjusted to a range of ≥ 94 wt% to ≤ 95 wt%, adding the binder solution to the second mixture to perform a second kneading process on a third mixture having a solid content adjusted to a range of ≥ 90 wt% to ≤ 93.9 wt%, and adding a conductive material solution to the third mixture to perform a mixing process on a fourth mixture having a solid content adjusted to a range of ≥ 70 wt% to ≤ 89.9 wt%.
