Seeing also shown in Figure 2ly, is the magnetic capacitance of present embodiment and other comparison schematic diagram of store energy media in the past.Because store energy media (for example: conventional batteries or super capacitor) in the past mainly is to utilize the mode of chemical energy to carry out store energy, therefore its store energy density will obviously be better than general electric capacity, and can be applicable to various electric power supply apparatus, but at the same time, the moment electric power output that it can produce also can be subject to chemical reaction rate, and can't discharge and recharge or carry out high power output fast, and it is limited to discharge and recharge number of times, grows variety of issue when excessively charging and discharging easily.Compared to this, because energy stored all is that mode with electrical potential energy stores in the magnetic capacitance, therefore, except have can with the store energy density of general battery or super capacitor coupling, more because of fully possessing the characteristic of electric capacity, and have long (high charge-discharge number of times), memory-less effect of life-span, can carry out characteristics such as high power output and fast charging and discharging, so the variety of issue that can effectively solve current battery and run into.
Please shown in Figure 3 in conjunction with consulting, be the structural representation of magnetic capacitance in the present embodiment.Magnetic capacitance 600 includes one first magnetic pole 610, one second magnetic pole 620, and a therebetween dielectric layer 630.This first magnetic pole 610 and second magnetic pole 620, constituted by electric conducting material with magnetic, and magnetize by suitable extra electric field, make and form magnetic dipole (Magenetic Dipole) 615 and magnetic dipole 625 in first magnetic pole 610 and second magnetic pole 620 respectively, to constitute a magnetic field in magnetic capacitance 600 inside, the mobile of charged particle impacted, thus the leakage current of inhibition magnetic capacitance 600.
Required benly is that the magnetic dipole 615 among Fig. 3 only is a schematic diagram with the direction of arrow of magnetic dipole 625.For the technical staff who has the knack of this skill, should recognize, magnetic dipole 615 is formed by stacking with the small magnetic dipole that magnetic dipole 625 is actually by a plurality of proper alignment, and in the present invention, magnetic dipole 615 and magnetic dipole 625 last direction and the indefinite that form for example can point to same direction or different directions.630 of dielectric layers are to be used for separating first magnetic pole 610 and second magnetic pole 620, with in first magnetic pole 610 and second magnetic pole, 620 place's stored charges, store electrical potential energy.In an embodiment of the present invention, first magnetic pole 610 and second magnetic pole 620 are to include the magnetic conductive material, rare earth element for example, 630 of dielectric layers are by titanium oxide (TiO3), barium monoxide titanium (BaTiO3) or semi-conductor layer, for example silica (Silicon Oxide) constitutes, therefore yet the present invention is not limited to this, first magnetic pole 610, second magnetic pole 620 and dielectric layer 630, all demand of visual product and select suitable other materials for use.
The operating principle of the magnetic capacitance of the present invention of metaphor explanation now is as follows.The material phenomenon that resistance changes under certain magnetic field is called " magneto resistance effect ", and magnetic metal and alloy material generally all have this magneto-resistor phenomenon, and under normal conditions, the resistivity of material only produces slight reducing in magnetic field; Under certain condition, the amplitude that resistivity reduces is quite big, exceeds more than 10 times than the magnetoelectricity resistance of common magnetic metal and alloy material, and can produce very huge magneto resistance effect.If further combined with Mace Weir-Wagner (Maxwell-Wagner) circuit model, also may produce very huge magnetocapacitance effect in the magnetic-particle complex media.
In electric capacity in the past, capacitance C is by the area A of electric capacity, the DIELECTRIC CONSTANT of dielectric layer
0, ε
rAnd the thickness d decision, be shown below.
C＝ε
0ε
rA/d
Yet in the present invention, magnetic capacitance 600 mainly is to utilize the magnetic dipole of proper alignment in first magnetic pole 610 and second magnetic pole 620 to form magnetic field, the electronics of internal reservoir is rotated towards same spin direction, carry out neat arrangement, so can be under same condition, hold more electric charge, and then can increase the storage density of energy.Be analogous to electric capacity in the past, the operation principles of magnetic capacitance 600 is equivalent to the dielectric constant that is used for changing dielectric layer 630 by magnetic field, so and can cause the significantly lifting of capacitance.
In addition, in the present embodiment, interface 632 between interface 631 between first magnetic pole 610 and the dielectric layer 630 and second magnetic pole 620 and the dielectric layer 630, all be to be a uneven surface, make the area of interface 631 and interface 632 compared to general smooth surface, A is bigger for its surface area, and can further promote the capacitance C of magnetic capacitance 600.
Seeing also shown in Figure 4ly, is the structural representation of first magnetic pole 610 in another embodiment of the present invention.First magnetic pole 610 of another embodiment of the present invention is a sandwich construction, includes one first magnetosphere 612, a separator 614 and one second magnetosphere 616.This separator 614 is made of nonmagnetic substance, this first magnetosphere 612 and second magnetosphere 616 then include the electric conducting material with magnetic, and when magnetization, by different extra electric fields, make the magnetic dipole 613 in win magnetosphere 612 and second magnetosphere 616 have different directions respectively with magnetic dipole 617, for example in a preferred embodiment of the present invention, the direction of magnetic dipole 613 and magnetic dipole 617 is for oppositely, and can further suppress the leakage current of magnetic capacitance 600.In addition, it is emphasized that, the structure of magnetic pole 610 is not limited to aforesaid three-decker, and can be in a similar fashion, constantly be staggeredly stacked with a plurality of magnetospheres and nonmagnetic layer, relend the leakage current that further suppresses magnetic capacitance 600 by the adjustment of magnetic dipole direction in each magnetosphere, even reach the almost effect of leakage current.
In addition, store, therefore all need to have the dimensions, otherwise tend to cause declining to a great extent of reserves efficient because in the past energy-storage travelling wave tube is mode with chemical energy mostly.Compared to this, magnetic capacitance 600 of the present invention, be that mode with electrical potential energy stores, and because employed material is applicable to semiconductor fabrication process (processing procedure), so can form magnetic capacitance 600 and peripheral circuit by suitable manufacture of semiconductor connects, and then volume and the weight that can dwindle magnetic capacitance 600, because this manufacture method is to use general semiconductor fabrication process (processing procedure) to reach, so do not repeat them here.
Seeing also shown in Figure 5ly, is the structural representation of a magnetic capacitance group 500 in another embodiment of the present invention.Brought forward is described, in the present embodiment, be to utilize manufacturing process (processing procedure) on a silicon substrate, to make a plurality of undersized magnetic capacitances 600, and by the proper metal processing procedure, between these a plurality of magnetic capacitances 600, form and be electrically connected, thereby constitute a magnetic capacitance group 500 that includes a plurality of magnetic capacitances 600, again with the supply of electric power source of magnetic capacitance group 500 as energy accumulating device or external device (ED).In the present embodiment, a plurality of magnetic capacitances 600 in the magnetic capacitance group 500 are that the mode with similar array is electrically connected, yet the present invention is not limited to this, and can be according to different voltage or capacitance demand, carry out suitable serial or parallel connection, to satisfy the supply of electric power demand of various different devices.
