  "textContent": "Provided are a lithium iron phosphate positive electrode plate. The lithium iron phosphate positive electrode plate includes a positive electrode current collector; and a positive electrode active material located on the positive electrode current collector. The positive electrode active material includes: first lithium iron phosphate particles having a volume average diameter D50 of 60 nm to 300 nm, optionally 60 nm to 200 nm, and a specific surface area greater than 15 m2/g, optionally 15 m2/g to 25 m2/g; and second lithium iron phosphate particles having a volume average diameter D50 greater than 800 nm, optionally 1000 nm to 1500 nm, and a specific surface area smaller than 10 m2/g, optionally 5 m2/g to 10 m2/g. A secondary battery prepared by using the lithium iron phosphate cathode plate according to the present disclosure has good dynamic performance and cycling performance.",
