Abstract
An electrode assembly, a battery cell, a battery, and an electrical device are described. The battery cell includes a negative electrode plate and a positive electrode plate. The negative electrode plate includes a porous current collector and a first tab connected to at least one end of the porous current collector. The positive electrode plate includes a body portion and a second tab connected to at least one end of the body portion. The body portion and the porous current collector are stacked along a thickness direction of the porous current collector. Along a first direction, neither end of the porous current collector extends beyond the body portion. The first direction is perpendicular to the thickness direction of the porous current collector.
