Background of the invention and the related Prior Art
Normally a lead-acid battery consists of several cells, which are filled with sulfuric acid. In operation, the battery should be free of venting, and the acid should flow back rapidly. Thus, the battery cover should be designed with venting hole and backflow hole. Also there should be maze and acid baffle to reduce electrolyte loss. Conventional storage batteries include a battery housing having housing and a cover for closing an open top end of the casing. The battery housing is a rectangular casing having múltiple compartments or cells for receiving cell plates and electrolyte therein. The cover devicé is heat sealed to an open top end of the battery housing casing. Lead-acid batteries typically comprise positive and negative electrode plates separated by micro porous separators, with sulfuric acid serving as an electrolyte. During discharge, as many sulfate ions are used at the positive electrode as at the negative electrode. However, at the positive electrode water is generated and the porosity decreases more than at the negative electrode, i.e., less surface área of the positive electrode is available to admit sulfuric acid.
Problems at the negative electrode are minimized by the fact that the sulfate ions have a potential which urges them toward the negative electrode. The availability of sulfuric acid at the positive electrode is further limited by the fact that acid transport in the micro porous separator is difficult, and thus the travel of acid to the positive electrode is resisted.
In order to attempt to compénsate for the limited availability of sulfuric acid at the positive electrode, the separators have heretofore been provided with ribs facing the positive electrode, which ribs define channels or pockets for confining sulfüric acid. Henee, access of the acid to the positive electrode is somewhat improved. In spite of this arrangement, the capacity of the cell continúes to be limited by the positive electrode due to the restricted access of acid to the positive active material. To increase capacity, the positive electrode can be made thinner and more porous, thereby facilitating travel of the acid thereto. The use of thinner plates, however, requires more electrodes and separators to maintain capacity and thus involves higher costs and also thinner current collectors with higher corrosión and shorter life as a result. The higher porosity also decreases the life of the cell due to rapid loss of active material from the positive electrode.

The novel features that are considered characteristic of the present invention are set forth with particularity in the appendéd claims. The invention itself, however, both as to its organization and its method of operation, together with additional objects and
advantáges thereof, will best be understood from the following description of certain specific embodiments, when read in connection with the accompanying drawings, in which: Tubular lead acid battery uses píate of type Tubular positive and fíat píate negative. In the tubular positive píate design the positive píate is composed of series of parallel spines emerging from the common connector or bus bar or top bar. The bus bar or current collector consist of series of spines that extend down from the top bar and is called spine comb. The lead oxide or paste is hold in micro-porous nonconductive tube termed as gauntlets which are placed over the individual spines of the Spine comb.
Assembling the spines, gauntlets, lead oxide and end cap together make a positive tubular píate. The spines and gauntlets are of circular or elliptical or square in shape. In the present invention the top bar and spine comb is modified in such a manner an appropriate amount of lead or lead alloy is replaced with the non – conductive engineering plástic material. The improved End cap is to hold lead or lead alloy connector that connects all individual spines on assembly and it is encapsulated or covered with plástic material to achieve high efficient cost effective novel tubular píate. The tubular píate can be used in negative píate and it replaces the conventional negative fíat píate type, making it a perfect tubular lead acid battery. Separator that is placed between the positive and negative píate can be eliminated heñ batteries are assembled using these new tubular plates. In the current invention the vertical spines originating from the top bar is modified with an engineering plástic connector which sealed the lead alloy top bar from outside húlding the individual spines at the origin point. The plástic top bar is of two parts which is sealed by ány advanced assembly mechanism.
The plástic top bar ís shaped in such a manner that ít holds the metal top bar as well as holds the gauntlets on assembly. The required active material in the form of powder or paste is held between the spine and the gauntlet; this is sealed using an improved end cap at the bottom. This novel end cap has lead or lead alloy as connectors, once inserted at the bottom it connects all the individual spines and créate a path for uniform distribution current fiow during its service life.
This tubular píate with plástic connector at the top and the innovative conductive end cap at the bottom makes it a unique positive píate of robust strength, cost effective and high efficient against the conventional. Moreover this positive píate can be very well adopted as negative píate also.
This both of positive and negative tubular plates results a riew tubular lead acid battery with features of robust structure, cost effective, long life and high efficient among the tubular battery technology. Moreover these batteries assembled with the tubular positive and negative píate may not require separator between them. This sepárator less battery is even more cost effective.
With the innovative tubular píate the specific energy of the battery can be improved by 30 % against conventional, that means higher watt hour capacity relative to the weightof the battery. Reduction of lead or lead alloy usage in top bar and spine comb (5) directly relates to the reduction in battery weight.
Top bar of the píate serve the critical function of transferring current to the spine and active material on charging vice versa on discharging. The phenomenon of corrosión due to the corrosive action of acid electrolyte coupled with current flow damages the top bar, resulting in greater rate of top bar corrosión and premature battery failure. The impugned invention has a protective nonconductive engineering plástic material on the lead alloy top bar that protects the lead alloy top bar surface against corrosive action of acid electrolyte. Moreover there is no direct exposure of lead alloy top bar surface with acid electrolyte, that ensures longer top bar Ufe with lower corrosión rate. The innovative end cap having connector bus bar is so novel that the current distribution is regulated uniformly across all individual spines there by effectively reduces the high end of charge voltage to bring the tubular battery to full charge. Additionally this feature enables quick recharge property against the flat píate batteries.
he phenomenon of corrosión due to the corrosive action of acid electrolyte coupled with current flow damages the spine, resulting in corrosión of one spine or múltiple spines with loss of capacity on ageing. The present invention solves this problem by providing necessary electrical connection at the bottom and avoids any series loss of capacity.
Due to the physical stress on the top bar, spine and gauntlet while discharging and charging, the active material lost from the positive píate will come in contact with negatíve electrode which is open flat píate type resulting in short circuiting and premature failure of battery. This innovative tubular positive píate having plástic connector on the top and bottom avoids any physical stress happening to lead alloy top bar and gauntlet while charging and discharging. This way it eliminates any loosening of positive active material from the píate which eventually suppresses the mossing effect. In addition the use of similar design negative píate adds additional security over any short circuits.
Manufácturing defects like sharp metal flashes, metal projections due to ejection pin, that are formed while performing Spine casting manufácturing process, may results in internal short & premature battery failure on service, if left unnoticed. The introduction of non-conductive plástic material at the lead alloy top bar, spine origin effectively protects the plates from these types of manufacturing defects. Lead acid battery are most widely used for all major applications like engine starting (SLI), stahdby, network and motive power. Based on the positive píate geometric shape, the lead aeid battery was classifíed as tubular píate (1) and fíat píate types, further on their physical characteristics like state of electrolyte, maintenance free property it is referred as flooded vented type and valve regulated type (VRLA). The tubular lead acid battery (11) of both the types found to be best fít for industrial applications like standby, network and motive power. The gauntlet (6) with multi tubes that are non- conductive micro porous with different geometric shape of circular or elliptical or square were used to hold the active material and made contact with the spine (la) and the gauntlet(6) will be closed by end cap or bottom bar (Ib) at the bottom.
On service life that is during discharge the used active mass changes its volume from 1 to 1.83 times and returns back on charging. This volume change is mainly compensated by the high mass porosity of around 60% of active material. The gauntlet with the circular or spherical or square cross section avoids swelling of the mass and keeps the structure together. Further corrosión speed is reduced by the gauntlet, because it is pressing the lead dioxide corrosión layer on to the spine surface, helps to protect spine against further corrosión. In addition, the tubular spines are made with 100 to 110 bar pressure unit called as high pressure die cast thus avoiding voids and crack with lower corrosión behaviour.
The lead acid battery which is made from tubular plates (1) has the following advantages and disadvantages.
Advantages
S Good electrical performances
S Long cycle life (30% longer service Ufe against flat píate)
S Tough and durable
S Provides best and most reliable power with 20% more electrical capacity Can deliver energy faster due to increased mass and surface área of active material and also ease with which acid circulates around the tubular píate
Disadvantages
• Low specific energy and derisity
• Sensitive to active material shedding and mossing that shortens battery life
• Sensitive to top bar breakage with significant loss of píate área
• Sensitive to spines being off centre of the tube with significant loss in capacity
• High end of charge voltage to bring the battery to full charge resulting in greater rate of corrosión to the lead and increased water loss from electrolyte solution.
This invention of tubular píate which is cost effective and high efficient is introduced to overeóme all the disadvantages Usted abo ve to gairt the useful life. Lead acid battery constitutes positive electrode of lead dioxide and negative of spongy lead. The positive electrode is termed as tubular píate type(l) whereas negative plate(l la) is flat píate type which is identical in appearance and function for both tubular and flat píate lead acid battery. Our invention of tubular lead acid battery (12), tubular píate (2) design that has metal current collectors termed as Lead alloy top bar (5a) consist of series of spine (5b) that extent downward and it is called spine comb (5).
The spines are usually circular or elliptical or square in shape, gauntlet (6) having multi tubes of micro porous and nonconductive in nature is inserted to the spine comb (5). A novel nonconductive engineering plástic top bar is introduced, it has síots to hold the lead alloy top bar (5a) and to extend cover the spine comb (5) from the top. This plástic top bar is termed as T-Guard Coupler (4) It plays three important functions
a) Protects the lead alloy top bar (5a) from breakage due to corrosión
b) Gloses or covers any lead projections that are formed during manufacturing process
c) Structural support to hold the gauntlet (6) with the spine (5b) and the lead alloy top bar (5a).
The T-Guard Coupler (4) is an innovative two piece design that can be joined mechanically as well as through modern ultrasonic welding method. The T-Guard Coupler (4) can also be formed by injection moulding as individual or along with the lead alloy top bar (5a) and spine (5b). The two cavities of the T - Guard Coupler (4) once joined or sealed cannot be separated by any means except breaking them by using external tools like hammer. The T-Guard Coupler (4) can also be locked with the lead alloy top bar (5a) and spine comb (5) using sealant that are acid resistant.
Alternatively, T-Guard Coupler (4) has necessary space to accommodate spine and lead alloy top bar on fitment. Single piece T-Guard Coupler (4) can be inserted through the spine comb (5) from thé bottom and fixed at the top similar to that of á two piece T-Guard Coupler. The single piece T-Guard Coupler (4) cannot be used in regular spine combs (5) that are having fins and guides on their individual spines.
This fins and a guide plays a critical function in guiding free flow of active material powder or paste while filling. This introduction of innovative T-Guard Coupler (4) will result in savings of lead alloy by 30% (wt. %) against conventional tubular píate The assembled T-Guard Coupler (4), lead alloy top bar (5a) with spine comb (5) is inserted with gauntlet (6) made of advanced 100% high tenacity polyester multi filament yarns that are impregnated with an acrylic resin system. Active material in the form of powder or paste is fílled in the space between the spine (5b) and gauntlet (6).
After filling, the spine comb (5) and gauntlet (6) bottom are closed by using ertd caps terméd as conductive interlink end caps (10). The conductive interlink end caps (10) comprises of two parts a)Metal specifically lead and lead alloy interlink chain with the provisión of inter locking individual spines(7), b) Plástic encapsulation (8) that protects the conductive interlink chain (7).
Conductive interlink end caps (10) plays major role in current distribution across the tubular píate. The network chain of conductive metal ensures that all the parts of the píate are electrically connected for good current distribution. Number of conductive interlinks and locks are decided from the design of spine comb (5) and number of individual spines. Plástic end capsulation can be performed through injection moulding process which protects the metal surface against the corrosión by acid electrolyte.
At any instance if one or more spine corrodes, the broken electrical connection will be restored by the conductive interlink end caps (10). This action is similar to fíat píate that uses crisscross network of lead alloy with spaces that are filled with active material during pasting process. This critical parameter and design upgrades the usage of tubular in positive as well as negative píate also. So this particular invention of cost effective high efficient tubular píate (2) can be used as negative electrode and replaces the conventional fíat píate type (1 la).
The tubular píate assembled batteries (12) possess compact structure, increased surface área and longer life. These batteries are 30% cost effective and 20 to 30% longer life than the conventional tubular (11) and fíat píate battery. Moreover these batteries will never face life limiting factors like mossing effect, direct short rising due to manufacturing defect, lead alloy top bar breakage, that are faced by conventional tubular (11) and fíat píate batteries.
Further the batteries made out of the tubular positive (2) and negative plates (2) does not íequired separator between them. The T-Guard Coupler (4) and conductive inter link end caps (10) modifíed to have Pitch retainer (9) that guides the píate to maintain necessary space between them while assembling in the absence of separator. This feature of battery without separator reduces overall cost of the battery.
Tubular lead acid battery that uses tall tubular positive píate, height more than 150mm is always subjected to poor current distribution and high end of charge vpltage on charging. To minimise this effect, conductive interlink middle caps (14) can be introduced at suitable distance over the length of the spine comb (5). This acts like a crisscross connection similar to that of fíat píate that results in better current distribution and lowers the end of charge voltage.
Without further elaboration, the foregoing will so fully illustrate my invention that others may, by applying current of future knowledge; readily adapt the same for use undér various conditions of service. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention.
