Currently, superconducting conductors are commercially available, and after cooling with liquid nitrogen (temperature – 195 °C), can transmit electric currents ten times higher than classic copper conductors. Without electrical resistance, and thus without energy losses, only direct current can be transmitted. Superconductors have this unique property due to the fact that the passing current is…

Superconducting tapes are attractive for use in magnets because they combine several favorable properties: a high upper critical field, good mechanical strength and a high critical current density of the ReBCO layer. The increase in current carrying capacity could be achieved by assembling many coated conductor (CC) tapes in parallel paths in a superconducting cable….
Silicon (Si) is a promising anode material for Li-ion batteries due to its high theoretical capacity (10 times higher than commonly used graphite) and abundant presence in the earth’s crust. However, the formation of an unstable solid-electrolyte interphase (SEI) and significant volume expansion during lithiation result in structural degradation, leading to a decrease in the…

Low-loss devices are needed tackle global warming issues. Devices using superconducting conductors represent possible solutions for these goals. Our colleagues have recently presented a method to characterize the effect of mechanical stress on the electromagnetic properties of superconductors. Low-losses devices and green energy solutions are a necessity to prevent global warming. Devices using superconductors could…
