Abstract
An electrode plate includes a current collector and a film layer comprising an active material and an adsorptive polymer disposed on at least one side of the current collector, wherein: the adsorptive polymer satisfies: 3≤m/n≤35, in which n represent a mass of the adsorptive polymer, and mrepresents a mass of a first substance that is obtained by: adding the adsorptive polymer to a predetermined electrolytic solution at 45° C. to form a polymer system, allowing the polymer system to stand for 60 hours at 45° C. and for ≥24 hours at 25° C., and then filtering the polymer system through a 200-mesh screen to obtain the first substance; and the adsorptive polymer further satisfies: 1.00≤m/n≤1.05, in which mrepresents a mass of a second substance, that is obtained by drying the first substance at 60° C. for ≥24 hours.
