Abstract
The present disclosure relates to a positive electrode sheet and a secondary battery. The positive electrode sheet includes: a current collector; a multifunctional coating disposed on at least one side of the current collector; and a positive electrode active material layer disposed on a surface of the multifunctional coating at the side away from the current collector. The components of the multifunctional coating include a solid electrolyte, a first conductive agent, and a first binder. The resistance of the multifunctional coating, the resistance of the positive electrode sheet, and the thickness satisfy a relational formula: 2 ≤ R<sub>1</sub>*R<sub>2</sub>*d ≤ 45, where R<sub>1</sub> is the resistance of the multifunctional coating, R<sub>2</sub> is the resistance of the positive electrode sheet, and d is the total thickness of the multifunctional coating.
