The brief

Analyst view

• Over 80% of China's 2G superconducting tape market in 2022-2024; 2024 capacity 1,334 km.
• Revenue grew from ¥36M in 2022 to ¥240M in 2024, turning a ¥73M profit in 2024.
• Filed for a ¥1.2B STAR Market IPO in June 2025 to fund a new tape plant in Pudong.

Technical approach

As reported

Template

Aligned crystal template on metal

A thin, aligned ceramic layer is grown on polished metal tape by ion-beam-assisted deposition, so the superconductor on top grows as one near-perfect crystal.

Superconductor

Fast laser deposition

A pulsed laser vaporises a rare-earth barium copper oxide (REBCO) target onto the moving tape. Its own heating system lets tape run at over 100 m per hour.

Tuning

Grades for magnets and grids

Added nano-defects pin magnetic flux so the tape carries more current in strong fields, which fusion and high-field magnets need.

Machines

Builds its own equipment

The company designs and makes its production machines, which lets it add capacity faster than buying from outside suppliers.
