In January 2026, the Institute of Physics, Chinese Academy of Sciences (IOP-CAS), released a landmark document—The 2025 Strategic Research Report on REBCO High-Temperature Superconducting Tapes.

For a long time, although China has been a global leader in the research and application of second-generation high-temperature superconducting (HTS) tapes, it remained heavily reliant on imported high-performance metallic substrates—the core raw material.

In the fabrication of high-temperature superconducting (HTS) substrates, the surface quality and thickness precision of the metallic base tape directly determine the performance of the final superconducting tape.

In humanity’s quest for clean energy, controlled nuclear fusion—often hailed as an “artificial sun”—is regarded as the ultimate solution to the global energy crisis. Realizing this vision hinges on generating ultra-strong magnetic fields capable of confining plasma at temperatures exceeding 100 million degrees Celsius.
