Embodiment Construction

[0038] In describing embodiments of the present invention, reference will be made herein to the accompanying Figure 1-10 , where like numerals indicate like features of the invention.

[0039] The high energy density capacitors of the present invention provide a solution for fast-charging, long-life capacitors to replace slow-charging, short-life batteries. The method of forming single or multiple capacitors of the present invention employs atomic layer deposition (ALD), metal oxide chemical vapor deposition (MOCVD), electrospray, sputtering, 3D printing, and other semiconductor fabrication equipment to produce submicron thin layers, and At least twelve (12) inch wafers and / or rectangular substrates can be produced, such as substrates for LED panels, which can be used in a variety of generations and sizes. Wafers can also be sawn into any shape or size and stacked to any height.

[0040] The present invention takes advantage of these advantages, utilizing large arrays of AL...

Abstract

A high energy density capacitor includes a substrate, a positive electrode, a negative electrode, a plurality of intermediate dielectric layers, and a metal layer deposited on each of the intermediate dielectric layers. Each intermediate dielectric layer contains sequential layers of high surface area dielectric material, electrolyte, and polar organic solvent deposited on the substrate. The plurality of intermediate dielectric layers and metal layers are arranged in series to form stacks, and at least one internal passivation layer is arranged between each stack. The positive and negative electrodes run along the height of the capacitor and have alternately deployed poles around their edges. The dipoles of the intermediate dielectric layer are aligned in opposite directions to the electric field generated between the positive and negative electrodes during charging.

Description

technical field [0001] Embodiments of the present invention generally relate to energy storage and wireless charging systems. Background technique [0002] Potential energy in capacitors is stored in an electric field, while batteries store potential energy in chemical form. Currently, chemical storage technologies produce higher energy densities than capacitors (capable of storing more energy per unit weight), but batteries require longer charging times. [0003] The energy densities of prior art supercapacitors are far lower than comparable sized batteries of any modern chemistry on the market. The highest energy density supercapacitor currently available on the market is the 6 Wh / kg Maxwell. Batteries such as Li-ion exceed 100 Wh / kg. [0004] In many applications (such as electric vehicles and other modes of transportation, including airplanes or trains, cell phones, utility backup storage, windmills, and any other type of electrical utility), there is a clear need for...
