Abstract: The present invention relates to an electrode plate, an electrochemical device and a safety coating. The electrode plate comprises a current collector, an electrode active material layer and a safety coating disposed between the current collector and the electrode active material layer, the safety coating layer comprising a fluorinated polyolefin and/or chlorinated polyolefin polymer matrix, a conductive material and an inorganic filler. The electrode plate can quickly open the circuit when the electrochemical device (for example, a capacitor, a primary battery, or a secondary battery) is in a high temperature condition or an internal short circuit occurs, and thus it may improve the high temperature safety performance of the electrochemical device.
