Room-Temperature Superconducting Wire SuperWire Passes Consumer Electronics Safety Certification for the First Time: Cooling-Free Superconducting Material Enters Mass Production

Room-Temperature Superconducting Wire SuperWire Passes Consumer Electronics Safety Certification for the First Time

On October 29, 2030, U.S. superconducting materials company SuperPower announced that its SuperWire room-temperature superconducting wire had passed UL (Underwriters Laboratories) safety certification. This is the world's first room-temperature superconducting material to receive consumer electronics safety certification.

SuperWire is based on the modified lead apatite material system discovered by the Korean team in 2024 (LK-99). After two years of optimization by SuperPower, the material demonstrates stable zero-resistance properties at ambient temperature (25 degrees Celsius) and pressure. The company uses powder metallurgy and hot-press sintering processes to produce the material into wire with a diameter of 0.5 millimeters.

SuperPower CEO Venkat Selvamanickam stated: "Passing UL certification means SuperWire can be integrated into consumer electronics products. This is a critical step for room-temperature superconductors moving from the laboratory to the factory."

SuperWire's current critical current density is approximately 1,000 amperes per square centimeter, far below that of low-temperature superconducting materials (approximately 1 million amperes per square centimeter), but sufficient for applications in consumer electronics such as signal lines and small inductors.

SuperPower has signed a cooperation agreement with Intel to evaluate using SuperWire for superconducting interconnects in next-generation chip packaging. The company plans to increase monthly production capacity to 100 kilometers of wire by 2031.
