An electrochemical apparatus includes a positive electrode plate. The positive electrode plate includes a positive electrode material layer. The positive electrode material layer includes a fluorine-containing polymer and a cyano-containing polymer. A ratio b/a of a mole number b of nitrogen to a mole number a of fluorine in the positive electrode material layer satisfies 0.1≤b/a≤0.5. Adding the fluorine-containing polymer and the cyano-containing polymer in the positive electrode material layer and controlling the ratio b/a satisfies the above relationship enable a good bonding effect between particles in the positive electrode material layer. In addition, after cyano functional groups interact with transition metal ions of the positive electrode active material at full charge, oxidizing ability of transition metal ions is weakened, reducing side reactions between the positive electrode material layer and electrolyte, thereby improving high-temperature performance of the electrochemical apparatus.
