  "textContent": "An electrochemical device includes a positive electrode, a negative electrode, a separator located between the positive electrode and the negative electrode, and an electrolytic solution. The positive electrode includes a positive current collector and a positive active material layer disposed on the positive current collector. The positive active material layer includes a positive active material. The positive active material includes an element A. The element A is selected from at least one of Al, B, Ca, Mg, Ti, Cu, Nb, Si, Zr, Y, or W. The electrolytic solution includes at least one of 1,3-propane sultone or a derivative thereof. A mass ratio of the element A in the positive active material to 1,3-propane sultone or a derivative is 1:0.2 to 1:50.",
