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−P1)×(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.

The breakable bubbles are disposed in the body. The breakable bubbles include at least a first bubble and a second bubble. A breaking pressure of the first bubble is less than a breaking pressure of the second bubble, so that the battery cushion can release a space occupied by the battery cushion in a progressive manner under different external forces. The battery cushion disclosed in this application can not only achieve a pre-tightening force required during assembly of the battery module but also effectively relieve an expansive force generated during working of the battery module.
