High energy density capacitor system and method

Abstract

A high energy density capacitor comprising a substrate, a positive electrode, a negative electrode, a plurality of intermediate dielectric layers disposed between the positive electrode and negative electrode, and a metal layer deposited on each of the intermediate dielectric layers. Each intermediate dielectric layer comprises sequential layers of a high surface area dielectric material, an electrolyte and a polar organic solvent deposited onto the substrate. The plurality of intermediate dielectric layers and metal layers are arranged in series to form a stack, and at least one an internal passivation layer is disposed between each stack. The positive and negative electrodes extend along a height of the capacitor and have poles in an alternating arrangement around an edge thereof, wherein the positive and negative electrodes are attached to periodic metal layers deposited on each of the intermediate dielectric layers. Dipoles of the intermediate dielectric layers are aligned in an opposite direction of an electric field created between the positive and negative electrodes while charging.

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 62 / 511,727 filed May 26, 2017, and U.S. Provisional Patent Application No. 62 / 556,640 filed Sep. 11, 2017, the entire disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]Embodiments of the present invention relate generally to energy storage.2. Description of Related Art[0003]The potential energy in a capacitor is stored in an electric field, whereas a battery stores its potential energy in a chemical form. The technology for chemical storage currently yields greater energy densities (capable of storing more energy per weight) than capacitors, but batteries require much longer to charge.[0004]Prior art ultra-capacitors have energy densities far below comparably sized batteries of any modern chemistry on the market. The highest energy density ultra-capacitor commercially available today is Maxwell at 6 Wh / kg. Batteries l...
