Negative electrode slurry, negative electrode pole piece, preparation method of negative electrode pole piece, battery and electric device

The present application relates to a negative electrode slurry, a negative electrode plate and a preparation method thereof, a battery and an electric device, the negative electrode slurry comprises a negative electrode active material and a chelate, the chelate is formed by coordination of a first metal cation and a ligand, the chelation reaction constant of the first metal cation and the ligand is KM, the chelating reaction constant of the second metal cation and the ligand is KN, the second metal cation comprises a transition metal cation in the positive electrode active material, and KM is less than KN. The cycle performance of the battery monomer can be improved.
