About Us

SuperOx Japan LLC was established in 2011 as the R&D Company. Its major activity is focused on the materials research and development of commercially sound technology and applications for energy related oxide materials with superior properties. Our interest includes materials and architectures for the high-Tc wires of the second generation (2G HTS) and their applications in variety of practical devices to aid sustainable development of human society and to meet the growing need for safer, cleaner and more reliable energy supply.

In the end of 2011 the laboratory facility was opened in the Sagamihara Incubation Center (SIC-3) and in April 2012 the first version of the equipment for production of buffer tapes and superconducting wires was installed. The first 50m long wire with the critical current of 300A was demonstrated in August 2012 and sales of commercial products started by the last quarter of 2012.
