Abstract: A functional polymer, an electrode slurry, an electrode plate, a battery and a power consuming device are described. The functional polymer comprises structural units represented by formula (A), formula (B) and formula (C). The functional polymer can increase the dispersion stability of the electrode slurry and also have the function of toughening, so as to increase the dispersion uniformity of the components in an electrode active layer while increasing its toughness, and further increase the cycling stability of the battery.
