    摘要： An electrochemical apparatus, including an electrolyte and a positive electrode, where the electrolyte includes ethylene carbonate and propylene carbonate, the positive electrode includes a positive electrode current collector and a positive electrode active material layer disposed on at least one surface of the positive electrode current collector, and the positive electrode active material layer includes a positive electrode active material, where percentages of ethylene carbonate and propylene carbonate satisfy a specific relationship, and under an X-ray diffraction (XRD) test, a peak intensity I003 of plane 003 of the positive electrode active material layer and a peak intensity I104 of plane 104 of the positive electrode active material layer satisfy a specific relationship. With the above configuration, the electrochemical apparatus of this application shows excellent performances, especially the high-temperature floating charge performance.
