Abstract
Provided is a positive electrode slurry, a secondary battery, a battery module, a battery pack and a power consuming device. The positive electrode slurry comprises a positive electrode active substance, a conductive agent and a binder, wherein the binder comprises a polymer A, and the polymer A comprises a structural unit derived from a monomer containing a cyano group, a structural unit derived from a monomer containing an amide group, and a structure unit derived from a monomer containing an ester group. In the present invention, the polymer A is used as the binder of the positive electrode slurry, such that the stability and processability of the positive electrode slurry are improved, and the adhesive force of the positive electrode plate is increased.
