Shanghai Superconductor’s"Key Technologies for the Preparation of High-Temperature Superconducting Tapes and Industrialization"project passed the scientific and technological achievement appraisal.

On March 27, 2021, the appraisal meeting for the scientific and technological achievements of the project “Key Technologies for the Preparation of High-Temperature Superconducting Tapes and Industrialization” was held in Shanghai.

The meeting was organized by the China Electricity Council, with Academician Gan Zizhao from the Chinese Academy of Sciences serving as the chairman of the appraisal committee and Academician Ding Wenjiang from the Chinese Academy of Engineering as the vice chairman. Other members of the expert panel included Professor Fu Yang, Vice President of Shanghai University of Electric Power; Professor Wen Haohu from Nanjing University; Senior Engineer Wu Xiaodong, Vice President of Shanghai Electrical Science Research Institute; Researcher Gu Hongwei from the Institute of Electrical Engineering of the Chinese Academy of Sciences; Senior Engineer Huang Hua, Deputy Director of the Electric Power Research Institute of State Grid Shanghai Electric Power Company; Professor Zhang Mingrui from Tongji University; and Professor Tao Bowan from University of Electronic Science and Technology of China.

The project “Key Technologies for the Preparation of High-Temperature Superconducting Tapes and Industrialization” was jointly undertaken by Shanghai Superconductor Technologies Co., Ltd. and Shanghai Jiao Tong University. It involved a series of core technology research and development for the key technologies of high-temperature superconducting tape preparation and the overall industrialization goals. The project achieved breakthroughs in the production of ultra-thin precision Hastelloy substrates and large-sized superconducting targets, solving the “bottleneck” problem of raw materials in the preparation of high-temperature superconducting tapes that had been controlled by foreign countries. This ensured the safety and controllability of the superconducting industrialization supply chain. The project also developed proprietary coating technologies and equipment, significantly improving the batch production level of high-temperature superconducting tapes. Furthermore, it invented a new packaging technology and developed superconducting low-resistance joints at the nano-ohm level, greatly enhancing the mechanical and electrical properties of high-temperature superconducting tapes.

The appraisal committee unanimously concluded that the project, based on the IBAD+PLD technology route, has developed a :second-generation HTS tape ultra-high-speed batch production technology and equipment” that reaches the “world-leading level.” It has achieved customized batch production capabilities for high-temperature superconducting tapes tailored to different application scenarios and has been widely applied in fields such as power generation, industrial energy saving, superconducting high-speed maglev trains, and compact controllable nuclear fusion large-scale scientific facilities, with significant economic and social benefits.

Qiu Wei, Chairman of Shanghai Superconductor, and relevant members of the project team attended the meeting.
