  "textContent": "A battery cell, a battery, and an electrical apparatus are described. The battery cell includes a case; an electrode assembly, the electrode assembly being provided with a tab; and a current collector plate including a first connecting plate and a second connecting plate that are connected, where the first connecting plate is connected to the tab by welding, and the second connecting plate is connected to the case by welding; and in a direction perpendicular to a thickness direction of the second connecting plate, a projection of the first connecting plate at least partially overlaps with a projection of the second connecting plate. The current collector plate can improve the stability and reliability of a connection between the case and the tab; in addition, the current collector plate has a small thickness, which can reduce occupied space in the battery cell to improve energy density of the battery cell.",
