Abstract: The present invention relates to the technical field of secondary battery materials. Disclosed are a polyacrylate binder and the use thereof, an electrode sheet and a lithium-ion battery. The polyacrylate binder provided by the present invention achieves good bonding performance by means of the regulation of the molecular weight of the binder and the contents of cyano groups, ester groups and carboxylate groups in the molecular chain of the binder, and the adjustment of the electrolyte absorption of the binder can also be achieved; and the binder is harmless to humans, and is environmentally friendly and inexpensive. The binder is introduced into an electrode sheet as a raw material for a water-borne safety coating; and on the basis of the good bonding performance of the binder, the water-borne safety coating can be firmly adhered onto the surface of a current collector of the electrode sheet, thereby reducing the surface contact resistance and improving the safety of a battery cell. Moreover, by limiting the contents of cyano groups, ester groups and carboxylate groups in the binder, the rate capability and high-temperature and low-temperature discharge performance of the battery cell can be significantly improved, thereby improving the safety performance and cycle performance of the battery.
