Abstract of US2008003499
The present invention provides a process for making a mineral battery using treated powdered polar crystal mineral and a treated liquid as an electrolyte. The polar crystal powder and liquid are either separately or after mixing together subjected to a rotating EMF. The powder-liquid mixture is inserted into a housing and compacted therein to form a mineral battery, along with an anode and a cathode and terminals. The preferred polar crystal mineral is tourmaline. In one embodiment, after the mixture is in the housing it is subjected to a voltage. In one embodiment the mixture is prepared and compacted into the housing and then subjected to a rotating EMF, and may then also be subjected to application of a voltage.
Description of US2008003499
BACKGROUND
[0001] Crystal structures can be divided into 32 classes, or point groups, according to the number of rotational axes and reflection planes they exhibit that leave the crystal structure unchanged. Twenty of the 32 crystal classes are piezoelectric. All 20 piezoelectric classes lack a center of symmetry. Any material develops a dielectric polarization when an electric field is applied, but a substance which has such a natural charge separation even in the absence of a field is called a polar material. Whether or not a material is polar is determined solely by its crystal structure. Only 10 of the 32 point groups are polar. All polar crystals are pyroelectric, so the 10 polar crystal classes are sometimes referred to as the pyroelectric classes. Polar crystals have opposite charges on opposite crystal faces.
[0002] Of the polar crystal minerals, tourmaline is a group name for about thirteen species of minerals that exhibit piezoelectrical characteristics. The Tourmaline group are silicated minerals containing boron, and they belongs to a trigonal or hexagonal, hemimorphic, hemihederal group. Its hemimorphisms are asymmetric with respect to the major axis, and its chemical formulae are complicated. A typical formula is:
[0000]
WX3Y6{NaX3Al6(BO3)3Si6O16(O,OH,F)4} Where W-Ca, K, Na
[0000]
X-Al, Fe2+, Li
[0000]
Y-Al, CR3+, Fe3+
[0000] Natural tourmaline occurs in crystalline schist, gneiss, contact metamorphic rocks, and pegmatite. Tourmaline is capable of being obtained in large crystalline form.
[0003] The following is a set of data for tourmaline taken from the web site http://en.wikipedia.org/wiki/Tourmaline:
[0000]
[0004] A characteristic of tourmaline is that the crystal is electrically polarized on one axis of the crystal. In its natural state there is a potential difference that exists along the face of one side of the crystal. The tourmaline crystal also distorts when an electric field is placed across the crystal.
[0005] Batteries are used to supply electric energy and are well known in the arts. The standard design of a battery consists of a metallic anode, a metallic cathode, separated by an electrolyte material. The generation of electricity is accomplished by separating the reactive components so that the transfer of energy must take place through an external circuit. The anode is the cell electrode where chemical oxidation occurs. The cathode is where chemical reduction occurs in the cell. The cell electrolyte completes the electric circuit by causing the flow of positive and negative ions (called cations and anions, respectively) between the anode and cathode. (See the Chemical Engineer's Handbook, John H. Perry's, 4 edition, 1963, McGraw Hill, pp. 25-25).
[0006] A United States patent application publication to Jyoya (Mar 10, 2005, Jyoya, US 2005/0052824) describes a battery using volcanic ash and other mineral ores. This application mentions 'other mineral ores' including the minerals of the tourmaline group. The construction of a battery of this type provides a generating potential of 1V (unloaded), 0.5V (loaded with a external resistance of 1K) and a current of 0.5 milliamperes.
[0007] A mineral battery is described in a Japanese patent to Maeyama (18 Apr. 2002, Maeyama, 02/31895, PCT/JP00/07059). This device consists of a powder of polar crystal material with water content of more than 5 mass % in a battery housing having an outer wall and with an anode, a cathode and with respective terminals. The preferred embodiment is created from the tourmaline group.
[0008] U.S. Pat. No. 5,601,909 to Kubo (Feb. 11, 1997), describes the fabrication of tourmaline to create 'permanent electrodes' by creating conditions to align the crystal structures.
[0009] A polar crystal battery (hereinafter called a "polar mineral battery") can be constructed by placing powdered polar crystal material with an electrolyte in a container, with terminals for the anode and cathode electrical connections. However, simply putting the materials together does not result in a useful battery. The present invention is a method for constructing a useful battery.

DETAILED DESCRIPTION
[0018] Exemplary construction of a polar mineral battery is shown in the WIPO publication number WO 02/31895, the content of which is incorporated herein by reference according to the English language translation made a part of this description as Attachment "A". In this description the term "battery" can mean a single cell battery or a cell of a multi-cell battery, and the term "cell" generally means a cell of a multi-cell battery.
[0019] The present invention resides in a method or methods of making an operable polar mineral battery. As will be seen, the broadest embodiment of the invention resides in use of a polar crystal mineral, and more narrowly, tourmaline as a preferred polar crystal mineral and a process to energize the polar crystal mineral. In a more particular embodiment the polar crystal material is energized by exposing it to a rotating EMF (REMF). Other steps and alternative embodiments are described below.
[0020] Steps for embodiments of the present invention are shown in FIG. 1. There are shown as two alternatives, Alternative 1 and Alternative 2. Other embodiments are described below.
[0021] The first step refers to the polar crystal material. Higher purity of the polar crystal material produces better performance. The preferred material is tourmaline. The material is rendered into a finely ground powder form by known means. The particle size range can be from sub-micron to about 400 mesh. While there is no lower limit to the particle size (all particle sizes referred to herein are average particle size, based on known measurement standards), it is considered that to obtain particle size under 1 micron is not cost effective with relation to the increased electromotive force available from smaller particle size. Further there is no upper limit but when over about 1 mm, the level of decrease of electromotive force is undesirable, therefore a preferred upper limit is about 1 mm. This results in a preferred particle size range of from about 1 micron to about 1 mm. A more preferred particle size is between about 2-5 microns.
[0022] A preferred material is tourmaline and its particle size range is as above, more preferably, about 3 microns.
[0023] A conductive liquid is selected. Water is the preferred liquid but other conductive liquids such as alcohol can be used. While tap water can be used, purer water is preferred. Distilled water is not recommended due to its lower conductivity. The quantity of water should be more than about 5%, more desirably over about 10%. It should be under about 30%, and more desirably under about 20%. A preferred range for the water is about 17-18%. The measurement of water content is done by comparing the difference in the mass weight of dried powder with the mass weight of powder divided by the mass weight of dried powder, this will be referred to as mass percent and is the standard for percentages herein unless the description is expressly different.
[0024] Dried tourmaline powder is produced by placing a tourmaline powder in an oven at 105[deg.] C. for a period of 1 hour.
[0025] It is also appreciated that when the polar crystal powder is prepared by crushing in air with 60-70% relative humidity, the air will contain about 6-8% of water content, in which case it can be used without additional water, or if a higher percentage of water is desired, it can be added to obtain a desired percentage of water.
[0026] Referring to FIG. 1; first the polar crystal powder is provided as described above.
[0027] Then, according to Alternative 1, the conductive liquid, such as water is subjected to an REMF, and separately, the polar crystal powder is also subjected to a REMF. Details of the REMF are described below. Then, the now energized polar crystal powder and liquid are mixed together to produce a mixture. The mixing step is described below. Then the mixture is compacted in a suitable battery housing and sealed.
[0028] Now referring to Alternative 2, it differs from Alternative 1 in that the conductive liquid and the polar crystal powder are first mixed to produce the mixture. Then the mixture is subjected to an REMF. Then the now energized mixture is compacted in suitable battery housing and sealed. This alternative 2 is the preferred method of those in FIG. 1. Various conductive liquids can be used such as water and alcohol. It is considered, with respect to the use of water, that purified water will provide better results. It is also considered that alcohol will provide higher current but for a shorter time. The preferred water percent is about 17% to about 18%.
[0029] As will be described below the battery resulting from these and in fact all alternatives will have an anode and a cathode embedded in the compacted mixture in the battery housing and connected to them connecting means to enable connection of the battery into a circuit.
[0030] The process of applying to the selected material the REMF is accomplished by placing it in the center of an REMF mechanism as shown diagrammatically in FIG. 4.
[0031] In summary, as shown in FIG. 1 in Alternative 1, the REMF is applied separately to the polar crystal material and the conductive liquid while in Alternative 2, the polar crystal material and the conductive liquid are mixed first. The preferred method is Alternative 2.
[0032] Application of the REMF improves the ability to obtain electricity from the battery, and it is considered that this is due to the EMF improving alignment of the charged crystals. The REMF is preferably provided using a three-pole mechanism that generates the REMF (see FIG. 4), the poles being located 120 degrees apart. Generally, applying the REMF longer will improve results. The length of time of application of the REMF is selected in order to obtain effect on the polar crystal material to a satisfactory degree. In the preferred embodiment the REMF is applied for a period of at least about 30 minutes to about 1 hour.
[0033] The REMF is applied at a selected frequency. Preferably a REMF frequency in the range of at least about 48 MHz to about 800 MHz is applied to the mixture of polar crystal material and liquid (Alternative 2). It is considered that for Alternative 1, in which the polar crystal material is treated separately, the frequency range is at least about 48 MHz to about 3 GHz. The frequency range for the liquid alone in Alternative 1 is preferably in the range of at least about 48 MHz to about 800 MHz, preferably from about 700 MHz to about 800 MHz.
[0034] With respect to the compacting step of Alternatives 1 and 2 of FIG. 1, it is performed with sufficient compaction to substantially expel air (which is nonconductive) entrained in the mixture. The compaction will also push the material particles closer together and increase the contact area of particles, which is considered to result in higher current. Also, the compaction will increase the amount of material in the battery, which will enhance its performance. While there may be some piezoelectric effect by this step, that is not the purpose. The compaction should preferably exceed about 3 atmospheres.
[0035] With respect to the sealing step of Alternatives 1 and 2, it is important to seal the battery quickly.
[0036] FIG. 2 shows the steps of the above procedure but with an additional step in each of Alternatives 1 and 2 the processes being designated alternative 1a and 2a respectively. That additional step is to apply a high voltage to the material in the battery housing, before sealing, that material of course now comprising the polar crystal material and the liquid that has been subjected to the REMF treatment and has been compacted into the battery housing.
[0037] FIG. 3 shows further alternatives, Alternative 3 and Alternative 4. In each of Alternatives 3 and 4, the mixture of polar crystal material and conductive liquid are first put into the housing (for the battery) and are then subjected to the REMF. This avoids transferring the mixture after application of the REMF since such transfer may degrade the effect of the REMF. In Alternative 4 the application of high voltage after application of the REMF is included, but in Alternative 3 it is omitted. It is considered that when the REMF is applied while the mixture is already in the housing that application of the voltage may not be necessary; however in Alternative 4 it is used nevertheless as it is considered to enhance the current available.
[0038] FIG. 5 shows schematically application of the high voltage. A preferred voltage is about 50,000 volts. The mixture of polar crystal material and liquid 10 is in a battery housing 12, and a voltage source 14 is connected and the voltage applied. The cover 16 is then put over the battery housing 12. Not shown are the conventional additional parts of a battery, which are well known, the anode, the cathode and terminals all of which are described and shown in the above referenced WIPO publication number WO 02/31895
[0039] After passing the voltage through the mixture, the battery is sealed, and it is still important to seal it quickly after the voltage treatment.
[0040] Exemplary construction alternatives of a polar mineral battery that may be applied to the present invention are shown in the WIPO publication number WO 02/31895, referred to above.
[0041] For a given quantity of polar crystal material and liquid mixture, dividing it up into separate batteries, or separate battery cells and connecting them in series and/or parallel gives better output than using the total volume as one battery or cell. This is schematically illustrated in FIG. 6. By configuring multiple mineral batteries or cells in series, the total electric potential may be increased in an additive fashion as shown in FIG. 6. By configuring multiple mineral batteries in parallel, the amount of current available may be increased in an additive fashion as shown in FIG. 6.
[0042] Assuming that the mixture is homogeneous, as it should be, the quantity Q can be divided by either volume or weight. The illustration showing division into three batteries or cells is exemplary as the number of divisions will depend on the practical manufacture of mixtures and the division into a battery having a number of such cells; all of which can be determined according to the desired commercial products.
[0043] FIG. 7 shows a flow chart for the process, when a given volume of material is divided into cells for an integral battery product. In Alternative 5, the PRIOR STEPS-I refers to the previously described Alternatives 1 a and 2a as shown if FIG. 2 in which after those steps but before the compacting step, fractional portions of the mixture will be compacted into a plurality of battery housings instead of a single battery housing, and will then be subjected to a high voltage, and then sealed. In Alternative 6, the PRIOR STEPS-II refers to Alternative 3 as shown in FIG. 3 in which after those steps but before the compacting step fractional portions of the mixture into a plurality of battery housings occurs and then each battery is subjected to a and sealed. As described above, in Alternative 6, a further alternative is to apply a high voltage to each battery after the application of REMF; that is replicating Alternative 4 with a plurality of battery housings. Also, each of alternatives 1 and 2 as shown in FIG. 1 can be used for multi-cell manufacture in which the compacting step is in a plurality of battery housings.
[0044] A battery or a cell constructed according to the present invention is shown in FIG. 8 in which a housing 20 is shown, constructed from a non-conductive material and consisting of a solid base 22 and a cap 24. The cap 24 has two holes for the anode lead 26 and the cathode lead 28 respectively. The leads are dimensioned to a size that either meets or exceeds the current requirements of the battery with an appropriate safety margin. The anode lead 26 is connected to anode plate 30 constructed from zinc (Zn) or other adequate material by a connecting element 32. The cathode lead 28 is connected to the cathode plate 34 constructed from copper (Cu), silver (Ag), gold (Au) or other adequate material by a connecting element 36. The cathode plate 34 may be solid or a mesh material to provide a greater contact area. The cathode plate 34 may also be constructed from a carbon material as is found in Leclanche cells. The anode plate 30 and cathode plate 34 are separated in the housing 20 and do not come into contact with each other. The mixture is in place around the anode plate and cathode plate as known in conventional batteries and cells.
[0045] The cap 24 is constructed in such a way that when placed base 22 a seal is created. The mineral battery or cell housing can be constructed from a variety of non-conductive materials, including plastic.
