- the present invention relates to a rechargeable battery, and in particular to a rechargeable battery incorporating a solid state material having longitudinally- extending holes into which longitudinally extending conductors are formed or placed.
- An accumulator comprising a capacitor having a pair of electrode plates, one on either side of a solid electrolyte is known from RU 2070756.
- the battery is charged by way of current flow through the electrolyte,
- An accumulator comprising a capacitor having a pair of electrode plates immersed in a liquid electrolyte is known From RU 2132585.
- the battery is charged by way of current flow through the electrolyte.
- a rechargeable battery comprising a piezoceramic component having a pair of attached electrodes is known from RU 2087066.
- the battery is charged by heating the piezoceramic component.
- a rechargeable battery including an energy storage member in the form of a solid state dielectric or semiconductor material having formed therein a plurality of holes with elongate conductors located within the holes and contacting the energy storage member at least at one point along their lengths, a first pair of electrodes adapted to apply a DC voltage therebetween and formed or located on generally opposed sides of the energy storage member in a first spatial orientation and a second pair of electrodes formed or located on generally opposed sides of the energy storage member in a second spatial orientation different from the first,
- the application of a DC voltage across the first pair of electrodes forms an electric field across the solid state material which induces electrostatic charges in the elongate conductors, thereby generating a voltage across the second pair of electrodes.
- the elongate conductors have substantially the same or similar spatial orientation to each other.
- enough of the conductors extend in substantially the same or similar direction so as to give the solid state material isotropic properties; that is to say, more conductors extend substantially in one given, predominant direction than in any other.
- the conductors and electrodes are preferably configured such that an imaginary line drawn between the first pair of electrodes extends substantially perpendicular to the predominant conductor direction and such that an imaginary line drawn between the second pair of electrodes extends substantially parallel to the predominant conductor direction.
- the energy storage is made from solid-state dielectric or semiconductor material containing holes with elongate conductors located within the holes.
- the elongate conductors are formed so that they are attached to the solid state body at least at one point along their length. At least some of these conductors have substantially the same or similar spatial orientation to each other.
- a first pair of electrodes is located on generally opposed sides of energy storage in a first spatial orientation and is adapted to apply DC voltage there between.
- a second pair of electrodes, being the output electrodes, is formed or located on generally opposed sides of the energy storage in a second spatial orientation different from the first one.
- the conductors and electrodes are preferably configured such that an imaginary line drawn between the first pair of electrodes extends substantially perpendicular to the predominant conductor direction and such that an imaginary line drawn between the second pair of electrodes extends substantially parallel to the predominant conductor direction.
- the elongate conductors are formed so that they contact the solid state material at least at some point along their lengths.
- the first pair of electrodes is formed or located tightly against the solid state material.
- the second pair of electrodes is formed or located tightly against the solid state material.
- the electrodes may be electro formed, electrodeposited or sputtered onto the solid state material. Alternatively, the electrodes may be formed separately and clamped, adhered or otherwise located on the solid state material.
- the electrodes may be formed from metals such as gold, silver, platinum or copper or combinations thereof. Other metals may be used where appropriate.
- the solid state material is a dielectric or semiconductor material, for example as described in the present applicant's copending International patent application WO 00/40506, the full disclosure of which is hereby incorporated into the present application by reference.
- the solid state material may be a dielectric ceramic material such as a solid state ciystalline ceramic material, including piezoceramic materials and solid composite mixtures of different ceramic materials.
- the solid state material may also be a semiconductor, such as silicon or gallium arsenide, among others.
- the solid state material may be a composite mixture of dielectric and semiconductor materials,
- the solid state material may be manufactured in accordance with the manufacturing processes described in WO 00/40506; that is to say, the holes may be formed by an electrical erosion process and the conductors may be formed by local ion precipitation within the holes.
- the holes may be in the form of pores, and preferably have a diameter of up to 200nm, more preferably from lOnm to 200nm.
- the conductors may be formed from metals such as gold, silver, platinum or copper or combinations thereof. Other metals may be used where appropriate.
- the conductors are preferably in the form of elongate filaments or fibres, and one or more filaments or fibres may be located within a given elongate hole.
- the conductors preferably have a diameter of up to 200nm, more preferably from l Onm to 200nm.
- the holes and the conductors advantageously have a longitudinal length of l OOnm to l OOOnm, although lengths outside this range may be appropriate in particular circumstances.
- the rechargeable cell of the present invention does not include any chemically active components, and is thus environmentally friendly. Furthermore, because there is little or no mechanical or thermal degradation during recharging, the cell of the present invention has an improved operational life as compared to existing accumulators. In some embodiments, the present invention provides a 20% improvement in operational life over existing rechargeable batteries.
- FIGURE 1 shows a solid state material provided with two pairs of electrodes.
- Figure 1 shows a solid state ceramic block 1 having a plurality of elongate pores in which are formed a plurality of elongate conductive filaments 2 made out of silver, The pores and the filaments 2 have a predominant longitudinal direction indicated by arrow 'A'.
- a first pair of silver electrodes 3 is electro formed, one on either side of the solid state material 1 , such that an imaginary line drawn between the electrodes 3 is substantially perpendicular to the predominant direction 'A'.
- a second pair of silver electrodes 4 is electro formed, one on either side of the solid state material 1, such that an imaginary line drawn between the electrodes 4 is substantially parallel to the predominant direction 'A'.
- a DC voltage applied across the electrodes 3 causes an electric field to be generated across the solid state material 1.
- the electric field induces electrostatic charges in the filaments 2, the charges then being caused to move along the filaments 2 under the influence of the electric field so as to generate a DC voltage across the electrodes 4, this voltage then being available to cause an electric current to pass through a load (not shown) connected across the electrodes 4.
- Example 1 Piezoceramic material with metal filaments laid in pores.
- Nanopores are formed on one of the endfaces of a piezoceramic blank produced by standard technology (a pressed piezoceramic charge with a binder is fired at a temperature of 1450°C and gradually cooled) by an electrical erosion method using a first probe of point diameter 20nm, made of antimony sulfoiodide (SSbl), by supplying pulses of negative polarity (pitch of treatment - 600nm, modifying voltage 4V; treatment time for each pore - 400nsec).
- SSbl antimony sulfoiodide
- a second probe made of silver (point diameter l Onm) is then used, with pulses of positive polarity supplied, to form silver nanofilaments in the formed nanopores by a method of local ion precipitation (pitch of treatment - 600nm; modifying voltage 2V; treatment time for each pore ⁇ OOnsec).
- the positioning of the first and second probes is carried out with the aid of a scanning tunnel microscope. The concentration of pores averaged 3 pores per ⁇ nr.
- a piezoceramic plate treated by the above method was subjected to study for strength (breaking strain). This was 3100N/mm 2 . whereas the strength of an analogous plate which had not been subjected to this treatment was 2200N/mm 2 .
- the electromechanical coupling coefficient which is inversely proportional to the value of the acoustic losses in the material, increased from 0.71 to 0.85,
