  "textContent": "The present disclosure provides a positive electrode sheet, a method for preparing the positive electrode sheet, and an application of the positive electrode sheet. The positive electrode sheet 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. The positive electrode active material layer includes a dispersing aid, a lithium iron phosphate positive electrode material, conductive carbon black, and carbon nanotubes. The dispersing aid, lithium iron phosphate positive electrode material, conductive carbon black, and carbon nanotubes in the positive electrode active material layer satisfies a relationship: 30≤(B1 × C1+B2 × C2+B3 × C3)/A × 0.01 ≤500. By reasonably adjusting the proportion and specific surface area of LFP in the positive electrode active material layer, the proportion and specific surface area of the conductive agent in the positive electrode active material layer, as well as an addition amount of the dispersing aid in the positive electrode active material layer, multiple characteristic parameters satisfy a specific relationship, which promotes dispersion of multi-component materials, ensures a good conductive network and binder distribution state, increases the peel strength, reduces the resistance of the positive electrode sheet, thereby reducing the DCR of the lithium-ion battery and increasing the rate-discharge energy efficiency of the lithium-ion battery.",
