POSITIVE ELECTRODE PLATE AND ELECTROCHEMICAL DEVICE

The present application relates to a positive electrode plate and an electrochemical device. 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 polymer matrix, a conductive material and an inorganic filler, wherein the polymer matrix is fluorinated polyolefin and/or chlorinated polyolefin and the weight ratio of the polymer matrix to the conductive material is 2 or more. The positive electrode plate may improve the safety performance during nail penetration of the electrochemical device such as a capacitor, a primary battery or a secondary battery.
