US Patent 7193261 - Quantum supercapacitor

Supercapacitors are electrical storage devices with high energy density storage and recharging capabilities made by materials having a large specific surface. However, traditional materials used for supercapacitors are difficult to integrate with electronic memory because heavy ions are used in the electrical storage. This patent proposes the use of nanostructured clusters in a specific spatial arrangement to facilitate such integration. Claim 1 reads:

1. A quantum supercapacitor comprising at least two electrodes, the interval between which is filled by nanostructured materials, including at least one cluster with a tunnel-transparent gap, wherein each cluster has a characteristic size determined in the range 7.2517 nm<=r<=29.0068 nm, the thickness of each tunnel-transparent gap being less than or equal to 7.2517 nm, the spacing between the electrodes being more than 7.2517 nm.
