本文报告了电力应用和磁体用涂层导体(CCS)开发的最新进展和剩余的材料挑战，并特别强调了目前在欧洲活跃的不同倡议。我们首先总结了CCS作为一种复杂技术产品被提出的科学技术范围，然后我们表明仍有很大的绩效提升空间。广泛描述了在欧洲项目EUROTAPES范围内探索的目标和CC架构，并强调了它们在产生新突破方面的潜力。该项目的总体目标是在学术和工业合作伙伴之间创造协同作用，在与CCS增强性能相关的几个科学问题上远远超过最先进的水平，并开发成本更低的纳米工程CCS，使用包含质量控制工具的高产量制造工艺，从而实现更高的产量。考虑了三个一般的应用目标，这三个目标将需要不同的导体结构和性能，因此策略是结合真空和化学溶液沉积方法来实现目标。描述了几个这样的方法的例子，涉及定义新的导体结构和形状，以及通过朝向纳米结构产生的新途径来增强涡钉扎。特别强调溶液化学方法。我们还描述了在将CCS改造成组合式导线和电缆方面所做的努力，这些组合式导线和电缆可以为电力系统提供良好的机械和电磁性能。最后，我们简要介绍了目前在欧洲和世界范围内正在进行的一些杰出的超导电力应用项目，以说明在满足将它们整合到新的电气工程范例中的需求方面取得的巨大进展。
This manuscript reports on the recent progress and the remaining materials challenges in the development of coated conductors (CCs) for power applications and magnets, with a particular emphasis on the different initiatives being active at present in Europe. We first summarize the scientific and technological scope where CCs have been raised as a complex technology product and then we show that there exists still much room for performance improvement. The objectives and CC architectures being explored in the scope of the European project EUROTAPES are widely described and their potential in generating novel breakthroughs emphasized. The overall goal of this project is to create synergy among academic and industrial partners to go well beyond the state of the art in several scientific issues related to CCs' enhanced performances and to develop nanoengineered CCs with reduced costs, using high throughput manufacturing processes which incorporate quality control tools and so lead to higher yields. Three general application targets are considered which will require different conductor architectures and performances and so the strategy is to combine vacuum and chemical solution deposition approaches to achieve the targeted goals. A few examples of such approaches are described related to defining new conductor architectures and shapes, as well as vortex pinning enhancement through novel paths towards nanostructure generation. Particular emphasis is made on solution chemistry approaches. We also describe the efforts being made in transforming the CCs into assembled conductors and cables which achieve appealing mechanical and electromagnetic performances for power systems. Finally, we briefly mention some outstanding superconducting power application projects being active at present, in Europe and worldwide, to exemplify the strong advances in reaching the demands to integrate them in a new electrical engineering paradigm.
