Problems solved by technology

However, common capacitor-based energy storage devices generally do not store energy in the small volume or weight, or at low energy storage cost, as in the case of batteries, which makes capacitors less desirable in some applications (such as electric vehicles). practical

Embodiment Construction

[0025] While various embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed.

[0026] The present disclosure provides a nonlinear capacitor as described above. In one embodiment of the non-linear capacitor, the operating voltage range is V 交点 to V 最大 , where V 交点 by the point V=V 最大 It is determined by the intersection of a straight line tangent to the relationship curve Q(V)=C(V)·V and the abscissa axis, and the voltage V 最大 with V 交点 The difference is bounded by the following ratios:

Abstract

The present disclosure provides a non-linear capacitor comprising a first electrode, a second electrode, and a dielectric layer disposed between said first and second electrodes. The dielectric layercomprises at least one organic compound selected from copolymer, homo-polymer, Sharp polymers, NLSD compounds and combination thereof which have at least one electropolarizable aromatic polycyclic conjugated core. A relationship between a capacity C of the capacitor and a voltage V between the electrodes is characterized by the monotonously increasing polynomial dependence (I), when the voltage Vsatisfies by following inequality 0<V<=V<max>, where the voltage V<max> is a maximum working voltage that does not exceed a breakdown voltage V<bd> and which is selected out of safety reasons, where at least one coefficient Ci is not equal to 0 when the index i ranges from 2 to m, and m=2, 3, 4, 5, or 6.

Description

technical field [0001] The present invention relates generally to passive components of electrical circuits, and more particularly to non-linear capacitors and energy storage devices including the same. Background technique [0002] Energy storage is an important component of a large variety of electronic devices, especially mobile devices and vehicles such as electric vehicles and gas-electric hybrid vehicles (herein also "hybrid vehicles"). Energy storage devices can be based on various physical effects. For example, electric fields can be used to store energy in capacitors, and chemical reactions (including ion movement) can be used to store energy in batteries. However, energy storage in capacitors may be limited by the geometry of current devices (e.g., 2-D capacitor plates with limited surface area) and low dielectric constant or low dielectric breakdown voltage, and batteries may be limited by electrochemical The relatively slow ion motion inherent in the reaction h...
