Estimating the term…
A composite current collector, an electrode plate, a secondary battery, and an electric apparatus are provided. The composite current collector includes a first metal layer, a bonding layer, and a second metal layer. The bonding layer includes a first surface and a second surface disposed opposite each other; the first metal layer is located on the first surface; and the second metal layer is located on the second surface. In the composite current collector, by disposing the bonding layer between the first metal layer and the second metal layer, peel strength of the first metal layer and the second metal layer can be enhanced, reducing the risk of detachment of the metal layers during processing.
A composite current collector, comprising a first metal layer, a bonding layer, and a second metal layer, wherein the bonding layer comprises a first surface and a second surface disposed opposite each other, the first metal layer is located on the first surface, and the second metal layer is located on the second surface.
