Abstract
A self healing high energy glass capacitor is provided. The capacitor can have a glass layer with a top surface and a bottom surface. A top sacrificial layer can extend across the top surface and a bottom sacrificial layer can extend across the bottom surface. In addition, a top electrode can extend across the top sacrificial layer and a bottom electrode can extend across the bottom sacrificial layer. In some instances the glass capacitor has an energy breakdown of at least 6 joules per cubic centimeter.
Claims18
A self healing high energy glass capacitor comprising:
- an alkali-free glass layer having a top surface and a bottom surface;
- a top sacrificial layer extending across and in contact with said top surface;
- a bottom sacrificial layer extending across and in contact with said bottom surface;
- a top electrode extending across said top sacrificial layer;
- a bottom electrode extending across said bottom sacrificial layer;
- and
- upon energy breakdown of said alkali-free glass layer at least one of said top sacrificial layer and said bottom sacrificial layer have a self healing property selected from the group consisting of selective ablation to promote self healing of said alkali-free glass layer, redox reacting to promote self healing of said alkali-free glass layer, and exothermic reacting to enhancing evaporation or phase change of at least one of said top electrode and said bottom electrode to clear a region around a failure location/defect and aiding in electrode removal from said fault region;
- said glass capacitor has an energy breakdown of at least 6 joules per cubic centimeter.
