Abstract

The invention relates to a cylindrical battery cell, a battery, an electric device, a manufacturing method and a manufacturing system. The cylindrical battery cell includes a shell having an opening and an electrode assembly. The electrode assembly is arranged in the shell, the electrode assembly comprises a diaphragm and a tab, in the axial direction of the electrode assembly, the tab is locatedat one end of the electrode assembly and extends towards the opening, the tab comprises a first part and a second part, the second part surrounds the periphery of the first part, and the diaphragm wraps the second part to isolate the second part from the shell; in the axial direction, the first part exceeds the second part and the diaphragm, and the second part does not exceed the diaphragm. The battery cell provided by the invention aims to solve the technical problem of short circuit of the battery cell.

Description

Technical field[0001]This application relates to the field of battery technology, in particular to a cylindrical battery cell, battery, electrical device, manufacturing method and manufacturing system.Background technique[0002]Since rechargeable batteries have the advantages of high energy density, high power density, many cycles of use and long storage time, they have been widely used in electric vehicles, mobile devices or power tools.
