  "textContent": "This application relates to a positive electrode plate and an electrochemical device. The positive electrode plate includes a current collector, a positive electrode active material layer and a safety coating disposed between the current collector and the positive electrode active material layer, wherein the safety coating includes a polymer matrix, a conductive material and an inorganic filler; and wherein the polymer matrix is fluorinated polyolefin and/or chlorinated polyolefin having a crosslinked structure. When the electrochemical device (such as a capacitor, a primary battery, or a secondary battery) is in a high temperature condition or an internal short circuit occurs, the positive electrode plate can quickly disconnect the circuit, thereby improving the high temperature safety of the electrochemical device.",
