| Ultra-fast Pulsed Laser Deposition Technolog

With years of R&D and production experience, Shanghai Superconductor has developed an ultra-fast superconducting film preparation technology using Pulsed Laser Deposition (PLD) coating method. This technology adopts unique process innovations such as high temperature in-situ stress control and multi-component synergistic optimization. It overcomes the traditional limitations of slow deposition speed and small sample space in PLD technology, achieving ultra-fast film formation while retaining the inherent advantages of PLD technology such as high coating quality and superior superconducting critical current performance.This technology addresses the low production efficiency of physical deposition methods, with characteristics including fast production speed, high yield and low cost, making it suitable for large-scale industrial production. After years of mass production testing, SST ’s high-quality HTS tapes achieve deposition speeds of 100nm/s, more than three times faster than similar technologies.

Ion Beam Assisted Deposition (IBAD) technology is the key to prepare the buffer layer, which provides the cubic texture for the growth of superconducting layers. Based on years of R&D experience, Shanghai Superconductor has innovated and adopted an advanced ultra-large ion source fast IBAD coating technology. This technology increases ion beam density while making its energy and density more uniform, enhancing the coating efficiency of the buffer layer by more than three times. This provides a solid foundation for the subsequent preparation of high-performance, high-stability superconducting layers.

| Precision Customized Metal Substrate Technology

SST continues to invest in R&D, persistently exploring the path of domestic production of substrates. The company has successfully developed precision customized metal substrate technology, addressing the material supply bottleneck in the industry chain. The domestically produced substrates feature customizability, precise controllability of thickness, and nanoscale flatness, making them suitable for ultra-thin, ultra-hard, and other customized parameter requirements. The ultra-thin substrate has the thickness of 30μm, and the ultra-hard substrate has the tensile stress exceeding 700 MPa.

| Non-Contact Low-Temperature Rapid Cooling Continuous Lamination Technology

The continuous lamination technology for superconducting tapes is the key process to ensure the stability of mechanical properties of superconducting tapes in actual application conditions, and is also the key indicator of the tapes' resistance to overcurrent impact. SST has developed a continuous lamination technology based on rapid tin slag processing, non-contact low-temperature rapid cooling, and passive automatic material collection. This technology involves various lamination materials including copper, brass, and stainless steel, addressing long-standing industry challenges such as stainless steel lamination, epoxy impregnation degradation, tape overcurrent burnout and tape cracking. As a result, the electrical and mechanical performance of 2G-HTS tapes has been significantly enhanced. The tapes can withstand industrial frequency impact currents of up to 2400A for 100ms without current degradation, and the tensile stress exceeds 700 MPa at 77K.

Through systematic research and industrial improvements, SST has resolved the challenge of introducing effective pinning centers during rapid coating processes. This has effectively suppressed the magnetic field-induced current decay, significantly enhancing the product's low-temperature high-field performance and production capacity. The tapes have achieved a leading international performance level of 1600A (4.2K, 10T) in low-temperature high-field conditions. This lays a crucial core material foundation for the construction of applications such as superconducting magnets and large scientific devices, promoting the development of China's high-temperature superconducting strategic industry.
