Magnesium diboride (MgB2) has advantages over other superconductors in terms of high performance and low costs for a wide range of applications, such as superconducting power cables, superconducting magnetic energy-storage devices, transformers, fault current limiters and motors. Besides the apparent economic benefits, the application of superconductivity will significantly reduce the green-house gas emission. This project will advance the practical applications of MgB2 by understanding the mechanism to improve critical current density.

在超导电力电缆、超导储能装置、变压器、故障限流器和电机等应用领域，二硼化镁具有其他超导体无法比拟的高性能和低成本的优势。除了明显的经济效益外，超导的应用还将显著减少温室气体的排放。本项目将通过了解提高临界电流密度的机理来推动镁的实际应用。
