Technical field
[0002] the present invention relates to be used to control the fluid regulating system that fluid turnover such as gas has the speed of the electrochemical cell of fluid consuming electrode and battery unit, and relate to auxiliary cell of fuel cell and the battery of the unpolarized air of battery and battery unit, particularly air that uses this fluid regulating system therein.
Background technology
[0003] battery unit of electrochemical cell uses from the fluid such as oxygen and other gases outside the battery unit as active material to produce electric energy, it for example is the battery unit of the auxiliary or fuel cell of air depolarising, air, and can be used for is various portable electric appts power supplies.For example, air enters in air depolarising or the air assisted battery unit, and wherein, air can be used as active positive electrode material and maybe can fill it again.Oxygen reduction electrode impels oxygen and the reaction of battery unit electrolyte and finally impels negative electrode active material to pass through oxygen and oxidation.Material in oxygen reduction electrode impels oxygen and electrolyte reaction, and is commonly called catalyst.But, some materials that are used for oxygen reduction electrode are not real catalyst, and this is because it can reduce at least in part, particularly in the discharge process of relative fair speed.
[0004] one type air depolarized battery unit is zinc/air cell unit.Such battery unit uses zinc as negative electrode active material, and has water-based alkalescence (for example KOH) electrolyte.Manganese oxide can be used in the air of zinc/air cell unit, and can carry out electrochemical reduction and cooperate with the oxidation of negative electrode active material, when particularly the oxygen diffusion rate in entering air electrode is not enough.These manganese oxide can be then low rates of discharge or in the shut-down stage by oxygen by oxidation again.
[0005] the air assisted battery unit is the hybrid battery unit, and it comprises consumable positive and negative electrode active material and oxygen reduction electrode.Positive electrode can be kept high rate discharge in the quite long period, but, by oxygen reduction electrode, oxygen aligns electrode and partly fills again in low rates of discharge or period of not discharging, and therefore, oxygen can be used for the pith in total battery unit discharge capacity.This means that the amount that is placed on the active positive electrode material in the battery unit can reduce, and the amount of negative electrode active material can increase, thereby increase the overall cell cell capability.The example of air assisted battery unit is at commonly assigned United States Patent (USP) 6,383,674 and 5,079, and is open in 106.
[0006] air depolarising, air advantage auxiliary, fuel cell are its high-energy-density, and this is because at least a portion of the active material of at least a electrode is from generating outside the battery unit or by the fluid (for example gas) outside the battery unit.
[0007] shortcoming of these battery units is, its maximum velocity of discharge that can realize may be subject to the speed that oxygen can enter oxygen reduction electrode.Past, made great efforts improving the speed that oxygen enters oxygen reduction electrode, and/or control can cause the admission velocity that is not suitable for gas of uneconomical reaction and can fill to be respectively applied in the battery unit and hold the water speed of increasing and decrease (depending on the relative dividing potential drop of steam that battery unit is inside and outside) that the exoelectrical reaction product increases volume or makes the emptying aperture space of battery unit drying such as carbon dioxide.The example of these methods can be at United States Patent (USP) 6,558, and 828, shown in United States Patent (USP) 6,492,046, United States Patent (USP) 5,795,667, United States Patent (USP) 5,733,676, U.S.'s publication 2002/0150814 and the international monopoly publication WO 02/35641.But, the diffusion rate that changes one of these gases also influences the diffusion rate of other gases usually.Even the two-forty and the CO that have made great efforts equilibrium oxygen to spread 2With the demand of the low rate of water, but only obtain limited success.
[0008] under the higher velocity of discharge, the more important thing is, make enough oxygen enter oxygen reduction electrode, but neutralization was not used in the period of battery unit in the low rates of discharge stage, minimized CO 2Increase with the importance of water diffusion.In order only to increase the air stream that enters in the battery unit in the period at high rate discharge, used fan to force air to enter that (for example United States Patent (USP) 6 in the battery unit, 500,575), but the controller of fan and use thereof can increase manufacturing cost and complexity, and, even the fan mini-fan also can occupy valuable volume in the battery pack of separately battery unit, many battery units and device.
[0009] other method that has proposed is that (for example, United States Patent (USP) 6 to use valve to control the air capacity that enters battery unit, 641,947 and U.S. Patent Publication thing 2003/0186099), may need external device (ED) but operate described valve, for example the electronic device of fan and/or relative complex.
[0010] another method is used the impermeable layer between oxygen reduction electrode and external environment condition, described film has valve, its can be owing to air pressure difference switch, for example when battery discharge because the consumption of oxygen and switch (for example the U.S. Patent Publication thing 2003/0049508).But, pressure differential may be less and may be subjected to the influence of the outer atmospheric conditions of battery.
[0011] commonly assigned U.S. Patent Publication thing 2005/0136321 discloses a kind of valve by actuator operated, and actuator response puts on potential change on the actuator and the described valve of switch.

[0101] in the embodiment shown in Fig. 9, first and second SMA lead-in wire 82a and 82b engage discrete actuator pin 304a and 304b respectively, and actuator pin 304a and 304b are connected to movable plate 66.In the embodiment shown in Fig. 9 A, single actuator pin 304 can be used for fluid regulating system 50.Under situation with single actuator pin 304, one side of the one SMA lead-in wire 82a double pointed nail 304, and the opposite side of the 2nd SMA lead-in wire 82b double pointed nail 304, thereby make SMA lead-in wire 82a and 82b activate described pin 304 in opposite direction, make plate 66 move to the left or to the right to open or to close described valve.In this embodiment, actuator pin 304 can comprise the lead-in wire receiving unit that is in differing heights, for example locking key or seam, SMA lead-in wire 82a and 82b in order to the correspondence that is bonded on differing heights make SMA lead-in wire 82a can not be in contact with one another or otherwise mutual interference mutually with 82b.
[0102], wherein demonstrates actuator pin 304 according to the alternative scheme that is used for fluid regulating system 50 of another embodiment referring to Fig. 9 B.Pin 304 demonstrations comprise 306a of first and second portion 306b, and 306a of first and second portion 306b are higher than the remainder of the pin 304 of general square shape, make SMA lead-in wire 82a engage described part 306a, and SMA lead-in wire 82b engage described part 306b.Upstand shown in described part 306a and 306b can comprise.Alternately, described part 306a and 306b can be included in the seam that forms in pin or other structures 304.Correspondingly, can adopt single or multiple actuator connected structures, thereby allow SMA lead-in wire 82a and 82b to activate described movable plate 66 with the described valve of opening and closing along either direction.
[0103] Figure 10 A and 10B demonstrate two end views of the valve 60 of contiguous jar of 34 outer surfaces use.Battery unit when Figure 10 A demonstrates and stops work, wherein, valve 60 cuts out and makes hole 64 and 68 misalignment.Position when second plate 66 that Figure 10 B demonstrates described valve moves to the enable possition, this situation will occur when using battery unit.This causes hole 64 and 68 to be aimed at and allows fluid to feed battery unit inside thus.As shown in the figure, SMA lead-in wire 82a and 82b can be attached to chassis 70 by a pair of spring contact site 76, wherein, but SMA lead-in wire crimping, clamping, soldering or be welded to spring contact site 76.
[0104] Figure 11 demonstrates another embodiment of the valve 60 that can be used in the different embodiments of the invention.Valve 60 comprises first plate 62 with a plurality of holes 64.Plate 62 can be with respect to chassis 70 and keeps static discrete plate or can be the jar of cell casing 30 or a part of covering.Plate 62 can be made of metal, and this metal can be magnetic or nonmagnetic metal.Valve 60 further comprises second plate 66 with a plurality of holes 68, hole 68 on quantity, size, shape and position corresponding to the hole 64 of first plate 62.Plate 66 can be magnetic or nonmagnetic metal.Be similar to previous embodiment, preferably the chassis 70 of being made by electrically non-conductive material comprises circumferential body 72, and circumferential body part 72 has opening 74, is used for bearing plate 66.Opening 74 is set to be slightly larger than plate 66 in one direction, thereby makes plate 66 make hole 64 and 68 removable alignings or misalignment thus so that valve 60 opening and closing with respect to plate 62 linear slide.Embodiment shown in Figure 11 is with the difference of aforesaid embodiment up to now, adopts the part of lever arm 84 as actuator 80.Lever arm 84 comprises the pivotal pin 86 that is undertaken in hole, seam or the recess 78 that forms in chassis 70, make lever arm 84 can be fastened to chassis 70 pivotly.This can for example realize as follows, that is: amplification and transformation recess 78 are to assemble and to extend partially into around pivotal pin 86 in the necked-in region between pivotal pin 86 and lever arm 84 main bodys, thereby pivotal pin 86 is positioned in the recess 78, but still allows lever arm 84 in recess 78, to pivot.Can use other modes that pivotal pin 86 is fastened to the chassis, for example, by the downward protuberance that extends from pivotal pin 86, this protuberance is undertaken in the hole in recess 78 base flange.Actuator pin 88 preferably extends downwards from the main body of lever arm 84, thereby it can be undertaken in the hole 67 that forms in second plate 66.This allows lever arm 84 fish plates 66, and thereby second plate 66 is slided with respect to first plate 62.In this ad hoc structure, a pair of SMA lead-in wire 82a and 82b are attached to the top surface of lever arm 84 by attached position 89.All the other ends of lead-in wire 82a and 82b can be attached to chassis 70.Lead-in wire 82a and 82b can be fastened to the recess in the chassis, and it for example is similar to recess 78.Lead-in wire can be fastening by any suitable mode, for example by bonding, by pin or by the head that will increase be assembled to carry out in the recess with limited opening fastening.The SMA lead-in wire is electrically connected to control circuit (not shown in Figure 11), and control circuit optionally puts on electric current SMA lead-in wire 82a and 82b in response to detected battery cell voltage.By this way, SMA lead-in wire 82a and 82b can draw lever arm along either direction in two rightabouts, thereby cause lever arm 84 that second plate 66 is slided with respect to first plate 62.In this case, chassis 70 is as the go between installation site of 82 ends of the pivoted position of lever arm 84 and SMA, also provides guiding with respect to plate 62 and guided plate 66 simultaneously.
[0105] SMA of other structures lead-in wire and bar can be used for the valve in the operating fluid regulating system.For example, SMA lead-in wire 82a and 82b can be by two discrete attached positions but not single attached position 89 is attached to lever arm 84.In alternative embodiment, SMA lead-in wire 82a and 82b all are secured to chassis 70 at two ends, wherein, are assembled in the groove 85 in the lever arm 84 by will go between 82a and 82b, and the center of each lead-in wire is connected to bar 84, as shown in Figure 34.
[0106] the SMA lead-in wire can be connected to the parts of fluid regulating system by the mode that is fit to.In one embodiment, at least one end of SMA lead-in wire 82 is positioned in the connector 87 that is fit to size, as shown in Figure 35.Preferably, SMA lead-in wire 82 is crimped onto in the connector 87.Alternatively, lead-in wire can be gluing before or after crimping, be welded or soldered to connector.But connector then in the corresponding aperture in the insertion parts (for example chassis 70 or lever arm 84) so that SMA lead-in wire 82 is connected to this parts.Preferably, connector 87 can have conductivity and can SMA go between 82 with a control circuit part between form and electrically contact, this part of control circuit is positioned on the parts surface in the described hole of qualification.Connector 87 is can be for example bonding by interference fit, conductivity, soldering or welding and be held in place in described hole.
[0107] in one embodiment, control circuit is used for the electric current of restricted passage SMA lead-in wire to be opened or off-position only at required time valve is moved to, in this case, and after electric current stops, the SMA lead-in wire can return to its original length (for example, elongation).When this thing happens, SMA lead-in wire can not remain on desirable position with described plate, and for example allowed it to slide into that part is opened or part is closed to the position.When existence is used to make slide plate to move to the opposite SMA lead-in wire of another location, especially true; When the SMA that activates extends, can draw slide-valve from the elasticity tension of the opposite SMA of actuating not electric current stops after.In this case, slide plate can remain on desirable position, has a mind to move apart this position up to this plate.A kind of exemplary means that is used for slide plate is remained on desired position is a lock mechanism.Can use any suitable mechanism.In one embodiment, the locking key of spring biasing can be cooperated with the protuberance of sled surface extension or the recess in the sled surface.Spring force can be selected as being enough to keep described plate to slide to prevent its accident, but enough little of to be overcome by the effect of opposite SMA lead-in wire easily and to make described plate slide into another desired position.
[0108] in another embodiment, keep slide plate to prevent its unexpected slip by the friction between slide plate and another battery unit or the fluid regulating system parts.Friction between described plate and miscellaneous part is enough to prevent unexpected the slip, but can be not excessive and make and effectively move to the another location by opposite SMA effect and be affected.Friction can be by selecting slide plate and miscellaneous part material, be coated on the coating of at least one part or at least one the texture in the adjacently situated surfaces is controlled.
[0109] fluid regulating system 50 can use various technology as described below to be fastened to battery unit 20 outsides.As shown in Figure 12, cover 100 can be set to have a plurality of legs 104, and leg 104 is from covering 100 inner surface and extend downwards and then by the hole 75 the correspondence position on the chassis 70, thereby makes leg 104 can be attached to jar 34 bottoms 35.Figure 13 and 14 demonstrates two kinds of different structures that are provided with shown in Figure 12.
[0110] in structure shown in Figure 13, cover 100 is formed by plastics.In this case, leg 104 can be ultrasonically welded to the basal surface of jar 34.In this case, will not exist between 34 with jar at cover 100 and be electrically connected.
[0111] in Figure 14, leg 104 is set to the recess/protuberance 106 that can form by modes such as punching presses in the metal cap 100.In this case, metal cap 100 can or be laser-welded to jars 34 basal surface 35 by resistance.
[0112] Figure 15 demonstrates the alternative that chassis 70 and cover 100 is connected to battery unit 20 outsides.In this case, through hole 105 is set to pass the hole 75 on chassis 70, is used for cover 100 is welded to jar 34.This welding also provides and is electrically connected between cover 100 and battery unit 20.
[0113] Figure 16 demonstrates another technology, wherein uses the conductive epoxy resin 107 in the hole 75 that is arranged on chassis 70 that metal cap 100 is fastened to jar 34.In another alternative scheme, fluid regulating system 50 can be fastened to jars 34 basal surface in the following manner, that is: use bonding agent, bonding agent and label the combination (not shown), by the chassis interference fit in one or more grooves of in jar 34 basal surfaces, suppressing, by other employing bonding agent carry out such chassis interference fit, by make time outer jar substitute crimping jar 34 in second jar of cover 100 places, by soldering or weld the stratiform chassis or by fluid regulating system is encapsulated in the epoxy resin.
[0114] be described as the preferred components of actuator 80 though use SMA to go between in preamble, but also can have used miscellaneous part or material, for example, linear electricity causes polymer and crooked electricity causes polymer, and it is relevant with artificial muscle.The potential advantage that such material provides comprises: simpler design, the electronic device of simplification or do not need electronic device and to the response of the ratio of voltage.
[0115] another consideration relates to the initial activation of battery.Battery can be configured to, and makes valve be in the enable possition, and hole 102 is protected by joint, and this is similar to traditional button-type air battery unit.Remove the venting afterwards of described joint with the activated batteries unit, start the electric control of described valve, and make the pot-life maximization of battery.Alternately, battery can be configured with the functional fluid regulating system.This will allow battery to be used at once by the consumer, but may be also need be in warehouse, shop shelf etc. be fit to seal and condition of storage, with prevent that moisture in the wet environment from invading and dry environment in the moisture effusion.
[0116] in aforementioned structure, jar 34 static plate 62 that are set to as valve 60.But, may it is desirable for the fixed head 62 that provides discrete rather than use jars 34, make pot bottom will keep the pattern in its hole, but, it can more similarly be to be used as air diffuser rather than as the integration section of valve module.In addition, static plate 62 can be separated with pot bottom, make expand at jar 34, crooked or operation that can interrupt valve 60 may be wrinkling the time.It should be noted that jar 34 can be by making than strong material and having than big thickness or difformity (for example, the protuberance in the bottom).Adopt another advantage of discrete static plate 62 to be that valve 60 can be assembled in advance by integral body, provide higher stability for lubricating fluid layer 69 thus.But, this may cause thicker battery.
[0117] though not shown in the accompanying drawings, but mark can be arranged at the outer surface of cell casing 30.Such mark can extend around the battery unit circumference, with the interface between further covering conductive contact 110 (will discuss hereinafter) and fluid regulating system 50 and the battery unit 20, and the interface between covering jar 34 and the lid 36.Enough parts of lid 36 and jar 34 and/or conductivity cover 100 can keep exposing, to provide electric contact terminal on the battery outside.
[0118] particular battery cellular construction shown in Fig. 1-3 is novel prismatic battery unit design.This structure on relative size and this battery unit square be different from traditional button-type air battery unit in nature.Be used for similar air electrode, anode, isolation part and the jar/cover material of conventional air battery unit at present thereby can be used in the battery unit 20.But, what those skilled in the art will recognize that is that battery unit 20 does not need to have given shape, size or relative scalar as shown in the figure.
[0119] Figure 17 demonstrates alternate embodiments of the present invention, and wherein, fluid regulating system 50 is arranged in cell casing 30 inside.Figure 18 demonstrates the sectional view of the part of this embodiment.As shown in the figure, cell casing is constructed to be similar to aforesaid mode, and its difference is that battery unit can be slightly thick between the inner surface that fluid regulating system 50 is contained in air electrode 40 and jar 34.In this embodiment, chassis 70 also can be used with aforesaid valve, actuator and control circuit 90 when being applied to battery unit outside.Similarly, jar 34 bottoms can be used as first plate 62 of valve 60, and can comprise a plurality of fluid intake ports 32 as hole 64.The difference of this embodiment is, second plate 66 along jars 34 inner surface but not its outer surface slide.In this embodiment and following other embodiment, chassis 70 and valve 60 can be held in place by liner 38.

[0140] adopts the fluid regulating system 50 of uneven temperature SMA lead-in wire to advantageously provide a kind of passive way, be used for when being higher than predetermined temperature, closing described valve and enter battery to stop fluid.By closing fluid regulating system 50 when the predetermined temperature that for example is higher than 60 ℃, can minimize or prevent cell degradation.In addition, close, stop described valve at high temperature to be opened by valve being moved when the temperature limit that for example reaches 60 ℃.Should be appreciated that the predetermined temperature of closing described valve can be greater than 45 ℃, and more specifically can be set at about 60 ℃.
[0141] according to an embodiment, SMA lead-in wire 82a can be set to have different size to produce different actuation forces with 82b, the actuation force that the actuation force that makes SMA lead-in wire 82b produce produces greater than SMA lead-in wire 82a.In the exemplary embodiment, SMA lead-in wire 82b has the bigger cross-sectional area than SMA lead-in wire 82a, for example bigger diameter.By bigger cross-sectional area, SMA lead-in wire 82b applies the bigger power of closing to movable plate when temperature reaches higher first temperature around.Should be appreciated that SMA lead-in wire 82a and 82b can have circular cross section, and the 2nd SMA lead-in wire has larger diameter.According to another embodiment, SMA lead-in wire 82a and 82b can have other shape of cross sections, for example oval, square or rectangular, wherein, the 2nd SMA lead-in wire 82b has more large scale than SMA lead-in wire 82a, causes bigger cross-sectional area, thereby causes bigger actuation force.In another embodiment, SMA lead-in wire 82a can have varying cross-section with 82b and amass and different phase transition temperatures, make SMA lead-in wire 82b at first to activate with the rising of environment temperature usually, described valve also keeps cutting out when being higher than SMA and going between the higher phase transition temperature of 82a when environment temperature is increased to even this causes.
[0142] referring to Figure 46-50, according to two embodiment, fluid consuming cells 10 is shown as battery unit 20 and the fluid regulating system 50 with battery, and fluid regulating system 50 has the fluid passage that passes chassis main body 300 to provide pressure balance in the middle of battery unit 20 and external environment condition.In an illustrated embodiment, the chassis is illustrated as the external mold forming body 300 with the central opening 332 and the flange 354 that extends internally usually.The battery unit 20 of fluid consuming cells, for example the air cell unit is connected on the top surface on chassis 300.Fixed head 62 with fluid intake port 64 is connected to the basal surface on chassis 300, and the movable plate 66 with port 68 is arranged in the middle of the lower wall and fixed head 62 of the flange 354 that extends internally, and makes plate 66 to move with respect to plate 62.
[0143] in Figure 46-49 illustrated embodiment, outer mold forming chassis main body 300 is illustrated as usually has first port, and first port is also referred to as inlet 350 and roughly between battery unit 20 and movable plate 66, and is communicated with opening 332 and battery unit 20 fluids.Chassis main body 300 also has second port, and second port is also referred to as outlet 352 and is arranged on the outside that the external mold moulding material leads to external environment condition.Outer mold forming chassis 300 is fabricated to the porose internal volume that has atresia outer 360 and fluid passage 356 is provided.According to an example, atresia skin 360 makes fluid that air can not be seen through substantially, and can comprise epoxy resin.Porose internal volume provides from the 350 pressure balance fluid flow passages 356 to outlet 352 that enter the mouth.Porose internal volume can comprise makes the impervious material of air, expanded microporous polytetra fluoroethylene-EPTEE material for example, or comprise that the porose material of non-texture flows through path 356 to allow limited air with low diffusion rate.Alternately or additionally, fluid passage 356 can comprise void volume, so that the path that allows the abundant restriction that air flows with low diffusion rate to be provided.Fluid passage 356 advantageously allows air 350 352 slowly to pass through to outlet from entering the mouth, but, fluid passage 356 can allow fluid to pass through along either direction between inlet 350 and outlet 352, to provide pressure balance between battery unit 20 and exterior circumferential environment.
[0144] inlet 350 of fluid passage 356 is communicated with the battery unit 20 of battery and the open volume fluid between valve plate 66 and 62.Existing pressure differential can allow air to move through fluid passage between the gas in the battery unit 20 of battery and the gas of external environment condition.When the battery unit of battery generates gas, described gas removable by limited fluid passage 356 external environment condition that arrives, to prevent the sealing between damage threshold plate 66 and 62.On the contrary, can allow gas to flow to inlet 350, but be restricted usually and make air can not freely be fed to the battery unit 20 of battery, thereby make the battery unit 20 usually can be when described valve cuts out with high rate discharge from exporting 352.
[0145] according to an embodiment, the air diffuser speed that fluid passage 356 has will be because humidity increase and decrease will cause annual no more than 10% battery unit capacitance loss at room temperature.Should be appreciated that, fluid passage 356 have pore volume to comprise to make the permeable substantially film of gas, being used to provides tortuous or limited air fluid path, but does not allow fluid freely and not to flow into limitedly in the battery unit 20.According to an embodiment, there is pore volume 356 can comprise tortuous fluid passage 356, for example pass through the fluid passage that baffle 358 provides shown in Figure 49.Baffle 358 has significantly increased the effective length of the air fluid path 356 that passes outer mold forming chassis 300, has increased the clear effective length of fluid flow path thus.According to another embodiment, tortuous fluid flow path can adopt the honeycomb pattern, and it can see through with the permission excess gas generally and escape in the external environment condition from battery unit 20, and makes the air that enters battery unit 20 minimum simultaneously.
[0146] in embodiment shown in Figure 50, the top surface of outer mold forming chassis main body 300 has therein the seam 334 that forms with helical shaped roughly, and seam 334 332 extends about 360 ° and guide chassis 300 outer surfaces into from square interior side opening 332 around opening.Hollow tube 336 is arranged in the seam 334 and has the general structure that is suitable for dimensionally being assemblied in the seam 334.Pipe 336 has first port that is communicated with interior side opening 332 fluids on battery unit 20 and chassis 300 at the one end, is also referred to as inlet 338, and has second port that is communicated with the external environment condition fluid at its other end, is also referred to as and exports 340.Fixed head 62 is shown as on the basal surface that is connected to chassis 300.Movable plate 66 be arranged on flange 354 times and with fixed head 62 contiguous seal, make plate 66 to move with the described valve of opening and closing with respect to plate 62.
