Abstract

Described in this patent application are devices for energy storage and methods of making and using such devices. In various embodiments, blocking layers are provided between dielectric material and the electrodes of an energy storage device. The block layers are characterized by higher dielectric constant than the dielectric material. There are other embodiments as well.

First claim

What is claimed is:

1. An energy storage device comprising:
first and second electrodes spaced apart;
a dielectric layer comprising SiO 2 or SiO x N y , and disposed between the first and second electrodes;
a first blocking layer disposed between the first electrode and the dielectric layer; and
a second blocking layer disposed between the second electrode and the dielectric layer,
wherein the dielectric constants of the first and second blocking layers are both independe…
