【Abstract】 The great advantages and promising prospects of YBCO coated conductor over other practical superconducting materials have spurred the related researches and rapid development of this field worldwide recently. In the present paper we firstly give a brief introduction to YBCO coated conductor and its typical structure,as well as two main technical routes for the scale- up preparation. Then we introduce the status and development for YBCO coated conductor around the world,including the existing research institutions and technologies they employed. More attention are given to the latest Chinese efforts on simplifying the buffer architecture and reducing the pyrolysis time for YBCO superconducting layer prepared by a cost-effective, chemical solution way. Artificial flux pinning for improved in-field performance of YBCO coated conductor is also introduced,and the attempts to maximize the flux pinning by introducing nanoparticles are addressed as well. Finally,the thriving and accelerating progress for the application of coated conductor and other superconductor materials,such as power cable,generator,transformer and magnet,are summarized briefly.更多还原
