Abstract
An electrode plate, a battery, and an electric power consumption device, the electrode plate includes a current collector and a film layer disposed on at least one side of the current collector, the film layer includes an active material and a plurality of types of fluorinated polymers, and the crystallinity of one of the plurality of types of fluorinated polymers is X c1 %, and the cold crystallization temperature is T c1 °C. The crystallinity of another fluorinated polymer among the plurality of types of fluorinated polymers is X c2 %, and the cold crystallization temperature is T c2 °C. Here, the plurality of types of fluorinated polymers satisfy 20% ≤ (X c2 - X c1 ) / X c1 < 400%, 30% ≤ (T c2 - T c1 ) / T c1 < 250%.
