Abstract

The present disclosure relates to a positive electrode slurry, a positive electrode for rechargeable lithium battery, and a method for manufacturing a positive electrode for a rechargeable lithium battery. A positive electrode slurry includes a positive electrode active material, a conductive material, a binder, and an additive for preventing gelation. The positive electrode active material includes a nickel-based first positive electrode active material having a layered structure, and a phosphate-based second positive electrode active material. A weight ratio of the first positive electrode active material to the positive electrode active material is in a range of about 50 wt % to about 95 wt %. The additive for preventing gelation includes at least one of oxalic acid, succinic acid, malic acid, fumaric acid, or a combination thereof.
