  "textContent": "A positive electrode plate 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, where the positive electrode active material layer includes a first positive electrode active material represented by chemical formula (1) and a second positive electrode active material represented by chemical formula (2): LiAFeMnTiPOS(1), and LiNaMO(2); and the positive electrode plate satisfies: 5.2≤R/Q≤13.5. Such a positive electrode plate can achieve a high specific discharge capacity of the electrochemical apparatus, thereby increasing energy density of the electrochemical apparatus. In addition, a relationship between compacted density R and single surface density Q of the positive electrode plate is limited, effectively improving cycling stability and rate performance of the electrochemical apparatus.",
