Abstract
A positive electrode slurry composition, and a positive electrode sheet prepared thereof, a secondary battery, a battery module, a battery pack and a power consumption apparatus are described. The positive electrode slurry composition includes a positive electrode active material, a pre-lithiation material, and a binder, where the binder is shown in Formula (II) where R, R, x, y, and z have meanings defined in the specification, a volume average particle size is D10≥0.3 μm, a volume average particle size D50 is 0.5-10 μm. The positive electrode slurry composition includes the binder in Formula (II) and the positive electrode active material with a specific particle size range, which is not easy to agglomerate and has high stability, and is conducive to improving machinability of the positive electrode sheet, and the binder in Formula (II) is conducive to improving bonding strength between the positive electrode active material and the pre-lithiation material.
