An example method for connectorizing a superconducting cable is described herein. The method can include depositing an oxide layer on a surface of a superconducting cable, electroplating a metal layer on the surface of the superconducting cable, and soldering a connector to the metal layer coated on the surface of the superconducting cable. The oxide layer allows the metal layer to adhere to the surface of the superconducting cable.
