Original Abstract Submitted
An electrochemical device includes a jelly-roll electrode assembly and a packaging shell. The jelly-roll electrode assembly includes a positive electrode plate, a negative electrode plate, and a separator. The positive electrode plate includes a positive current collector, a first layer, and a second layer. The first layer includes inorganic particles. Based on a mass of the first layer, a mass percent of the inorganic particles is greater than or equal to 50%. The second layer includes a positive active material. A thickness of the first layer is dμm. An area of orthographic projection of the first layer is Smm, an area of orthographic projection of the second layer is Smm, satisfying: d/S≥2×10, and d/S≥2.5×10. The first layer is in contact with the packaging shell.
