        以REBCO(REBa₂Cu₃O_7-δ,RE代表稀土元素)为代表的高温超导带材，因其液氮温区优异性能，在能源、医疗、大科学装置等领域具有重要战略价值，但目前在长带一致性、制备成本和工程可靠性等方面仍面临严峻挑战。未来发展需转向“材料-工艺-应用”协同创新，通过增强磁通钉扎、优化多层结构界面与力学性能，并结合规模化、智能化制备技术，推动高性能带材的低成本稳定生产。文章围绕REBCO带材的核心应用需求、研发现状与趋势、关键科学技术问题及国产化发展路径展开分析，为我国在该领域的自主创新与产业引领提供参考。

        High-temperature superconducting materials, represented by REBCO(REBa₂ Cu₃O_7-δ, where RE denotes rare-earth elements), are of significant strategic importance in fields such as energy, healthcare, and large-scale scientific facilities due to their excellent performance in the liquid nitrogen temperature range. However, they still face severe challenges in long-tape uniformity, production cost, and engineering reliability. Future development must shift toward a “material-processing-application” collaborative innovation model, aiming at enhancing flux pinning, optimizing the interfaces and mechanical properties of the multilayer structure, and integrating scalable and intelligent fabrication technologies to promote the low-cost and stable production of high-performance tapes. This study analyzes the core application requirements, research and development status, trends, key scientific and technological bottlenecks, and domestic development pathways for REBCO tapes, providing insights to support independent innovation and industrial leadership in China's High-temperature superconducting field.
