The present disclosure discloses a polyacrylate-based binder and use thereof, an electrode sheet, and a lithium-ion battery. The present disclosure relates to the technical field of secondary battery materials. The polyacrylate-based binder provided by the present disclosure achieves good adhesion performance by regulating the molecular weight and the contents of cyano, ester, and carboxylate groups in the molecular chain of the binder. It also allows for the adjustment of the electrolyte uptake rate of the binder. Furthermore, the binder is harmless to humans, environmentally friendly, and low in cost. By introducing the binder as a raw material for the aqueous safety coating in the electrode sheet, its excellent adhesion performance allows the aqueous safety coating to firmly adhere to the surface of the current collector of the electrode sheet, which reduces surface contact resistance and enhances the safety of the battery cell. Furthermore, by limiting the contents of cyano, ester, and carboxylate groups in the molecular chain of the binder, the rate capability and high and low-temperature discharge performance of the battery cell can be significantly enhanced, thereby improving the safety performance and cycling performance of the battery.
