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