Zusammenfassung:	The present disclosure provides a current collector, a preparation method for a current collector, a negative electrode, and an electrochemical energy storage device. The current collector includes: a first polymer layer; a metal layer, the metal layer being disposed on a side of the first polymer layer; and a second polymer layer, the second polymer layer being disposed on a side of the metal layer facing away from the first polymer layer; and in a direction from the first polymer layer to the second polymer layer, the current collector having a number of through-holes that penetrate the current collector.
