Abstract

A secondary battery includes a positive electrode plate. The positive electrode plate includes a positive electrode current collector and a coating disposed on at least one surface of the positive electrode current collector. The coating includes a first coating and a second coating. The first coating is disposed between the positive electrode current collector and the second coating, and the first coating includes an inorganic material, a conductive agent, a binder, and a dispersant. Based on total mass of the first coating, a mass percentage of the inorganic material is w<1>, where 15%≤w<1>≤50%, a mass percentage of the conductive agent is w<2>, where 15%<w<2>≤40%, a mass percentage of the binder is w<3>, where 30%≤w<3>≤50%, and a mass percentage of the dispersant is w<4>, where 0≤w<4>≤5%.
