Abstract: The present application provides a current collector and a preparation method therefor, a secondary battery, a battery module, a battery pack and a power consuming device. The current collector may comprise a strength enhancement layer and a current collecting layer. The current collecting layer may comprise a first foam metal layer that may be stacked and bonded with the strength enhancement layer and a second foam metal layer that may be provided on the side of the first foam metal layer away from the strength enhancement layer and may be stacked with the first foam metal layer, the second foam metal layer having a porosity greater than that of the first foam metal layer.
