Zusammenfassung:This application discloses an electrode assembly, a battery cell, a battery, and an electric device. The electrode assembly includes a first electrode plate and a second electrode plate that have opposite polarities, where the first electrode plate and the second electrode plate are stacked. The first electrode plate includes a first active substance portion and a plurality of first inactive substance portions protruding from the first active substance portion, and the plurality of first inactive substance portions are stacked. A connection layer is disposed between at least two adjacent first inactive substance portions, and the connection layer is spaced from the first active substance portion in a first direction and is configured to connect two adjacent first inactive substance portions, where the first direction is a direction in which the first inactive substance portions protrude from the first active substance portion. The connection layer connects two adjacent first inactive substance portions to produce a constraint between the two first inactive substance portions. In a bending process, the connection layer can reduce dislocation and bifurcation of the two first inactive substance portions, reducing short circuit risks and improving safety performance.
