However, support for the operation of electronic power source behind the evolution of the speed gradually been behind the evolution of the speed of the product. The same problem also occurs in the automotive industry, with the shortage of oil in the future, electric cars and hybrid vehicles is a major mainstream, with a variety of mixed secondary battery energy storage capacitor is also the idea become a reality. So we need a very high stability, long life, high capacity of the capacitor requirements. In this project, we use magnetron sputtering deposition technique to prepare magnetic capacitor elements by integrating iron-platinum alloy (Fe54Pt46) and BaTiO3 and get the property of high energy density, high power density, long cycle life and high safety advantages. Same as conventional capacitor devices, the process of charging-discharging do not involve oxidation-reduction reaction so it can charge and discharge quickly. Complete solid sate structure not only have high safety but also maintain above 80% of original electricity storage after many charging-discharging cycles. The most important characteristic is the improvement in dielectric property by the magnetic field which is produce by device itself. It increase the number of charge storage and further extend the durability in application site. We start from fundamental magnetism and dielectric property and currently found 327% (1kHz) magnetic capacitance effects at room temperature, and will continue to cooperate with the appropriate research methods to achieve the best storage performance.奈米級應力太陽能電池nano-stresssolar cell
