Abstract
This application provides a lithium-ion battery, a positive electrode plate for a lithium-ion battery, and an apparatus. The lithium-ion battery includes a positive electrode plate that includes a positive current collector and a positive active material layer arranged on at least one surface of the positive current collector. A positive active material in the positive active material layer includes a positive active substance I and a positive active substance II. The positive active substance I is a layered lithium nickel transition metal oxide. The positive active substance II is an olivine-type li-containing phosphate. The positive electrode plate satisfies 2.5≤N/(PD×(1−P)×(1−A))≤21. The positive electrode plate for a lithium-ion battery has relatively high energy density, and a high transmission rate of lithium ions, which effectively increases instantaneous discharge power under a low SOC while ensuring high volume energy density of lithium-ion batteries using the positive electrode plate.
