  "textContent": "This application relates to a positive electrode plate and an electrochemical device. The positive electrode plate includes a current collector, a safety coating, a difficultly soluble layer and a positive active material layer, wherein the safety coating, the difficultly soluble layer and the positive active material layer are successively disposed on the current collector; wherein the safety coating includes a polymer matrix, a conductive material and an inorganic filler; wherein the difficultly soluble layer includes a binder and a conductive agent, and wherein the binder of the difficultly soluble layer has a solubility in an oil solvent smaller than the solubility of the polymer matrix of the safety coating in such oil solvent. 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.",
