Nickel-rich layered cathodes (for example, NCM811) hold great promise for practical applications in high-energy density lithium-ion battery technology. However, a nickel-rich cathode has poor cyclic stability because of the structure degradation induced by repeated cycles and excessive formation thick cathode–electrolyte interface (CEI) layers. Poly(vinylidene difluoride) (PVDF) is typical binder used to form positive electrode, which nevertheless lacks functionality suppress control CEI...
