Conductive metal sheet

The invention provides a conductive metal sheet, and the conductive metal sheet is suitable for electric conduction of a battery cell. The conductive metal sheet comprises a connecting module and a plurality of conductive parts; each conductive part is respectively used for contacting at least one battery core, and the connecting module comprises one or two first connecting parts and two second connecting parts. The sectional area of the first connecting part is less than that of the second connecting part, and the first connecting part is connected with the plurality of conductive parts through the two second connecting parts on the two sides. When one battery cell connected with the conductive part fails, an overcurrent may also flow between the faulty battery cell and the conductive metal sheet, and the first connecting part with a smaller sectional area in the conductive metal sheet is fused by the overcurrent to disconnect the faulty battery cell from other normal battery cells soas to control the out-of
