Abstract

A battery cell, a battery, and an electrical apparatus are disclosed in the present application. The battery cell includes a shell, an electrode terminal, an electrode assembly, a first adapter, and a second adapter. The shell has a first wall. The electrode terminal is mounted on the first wall in an insulated manner. The electrode assembly includes a main body part, a first tab, and a second tab. The first tab and the second tab have opposite polarities. In a thickness direction of the first wall, the first tab and the second tab are both arranged at one end of the main body part facing the first wall. The first adapter includes a first connecting portion and a second connecting portion, the first connecting portion is connected to the first wall, and the second connecting portion is connected to the first tab. The second adapter connects the electrode terminal and the second tab. In the thickness direction of the first wall, an orthographic projection of the first adapter does not overlap an orthographic projection of the second adapter, and in the thickness direction of the first wall, an orthographic projection of the first connecting portion does not overlap an orthographic projection of the second tab. The technical solution provided in the present application is capable of improving the reliability of batteries.
