Description
SPECIFICATION
Multicell electric storage batteries of recombination type
The present invention relates to multicell electric storage batteries of recombination type and is particularly though not exclusively concerned with such batteries of lead acid type. Recombination batteries are those type of batteries which contain a reduced amount of electrolyte and in which gases evolved during operation or charging are not vented to the atmosphere but are induced to recombine within the battery.
Conventional lead acid electric storage batteries of both flooded electrolyte and recombination types generally include a substantially rectangular section container divided internally by a number of intercell partitions into compartments each of which contains a cell pack. The cell packs comprise a plurality of alternate positive and negative plates which extend parallel to the intercell partitions and adjacent pairs of cell packs are connected together by intercell connectors which connect the plates of one polarity in one cell pack to those of the opposite polarity in the adjacent cell pack. The connection to the plates is conventionally effected by means of an upstanding lug at one end of the upper edge of the plates.
The provision of the lug at one end of each plate results in the electrical pathway within each plate being relatively long and the electrical pathway to an adjacent cell which includes both the intercell connector and usually also a plate strap connecting together the lugs of the same polarity in the same cell is also relatively long thus leading to a substantial internal resistance of the battery.
In batteries of recombination type it is usual for the cell packs to be under a compressive force since this is believed to be essential in such reduced electrolyte batteries if the plates are to be in contact with the quantity of electrolyte necessary for their electrochemical performance. In batteries in which the plates extend parallel to the intercell partitions, this compressive force is exerted on the end walls of the battery which tends to cause these walls to bow outwardly. In orderto avoid this bowing and perhaps ultimate rupture of the battery container it has been necessary to manufacture the end walls of such recombination batteries thicker than is normal in equivalent flooded electrolyte batteries or alterna timely to provide them with reinforcing ribs.
British Patent Specification No. 2070844 of the present applicants discloses a battery of recombination type which seeks to overcome the problems referred to above. In this battery the plates extend perpendicular to the intercell partitions and thus have a substantially reduced length as compared to the plates in those batteries in which the plates extend parallel to the intercell partitions. This has the effect of shortening the current paths within the plates thereby reducing the internal resistance of the battery and in addition the compressive force on the individual cell packs is accommodated by the end walls of the container and also the intercell partitions which are placed in tension with the result that the end walls do not tend to bow outwardly and thus do not require additional reinforcement.In the batter disclosed in this prior specification, the plates, with the exception of every alternate plate in the two end cells, is one half of an integral bipolar plate comprising a negative plate in one cell connected to a positive plate in the adjacent cell by an intergral bridge piece. This construction obviates the requirement for plate straps connecting together plates of the same polarity in each cell and leads to a reduced intercell resistance. However, the battery is assembled by sequentially inserting bipolar plates into the container and it is found that the handling of such plates presents certain problems since they are found to be extremely flexible and the bridge piece or pieces tend to bend or even rupture during assembly of the battery.In addition, individual sheets of separator material must be placed between each adjacent pair of plates in each cell and since the interleaving of the plates with the separator material must be performed within the battery container this is found to be a time consuming procedure.
Accordingly it is an object of the present invention to provide a multicell electric storage battery of recombination type which both overcomes the problems referred to above and is easier and cheaper to assemble than that disclosed in British Patent Specification No. 2070844.
According to the present invention a multicell electric storage battery of recombination type includes a substantially rectangular section container sealed by a lid and having two or more cells each containing alternating substantially planar positive and negative electrodes interleaved with compressible fibrous absorbent material and substantially no free unabsorbed electrolyte, adjacent cells being separated by a respective substantially planar intercell partition and the electrodes extending substantially perpendicular to the adjacent intercell partition, the electrodes each having an upstanding lug and being arranged so that the lugs extend in lines of a single polarity each adjacent the end walls of the container and the intercell partition or partitions, each pair of lines of lugs of opposite polarity adjacent the or each intercell partition being connected by a continuous elongate metallic bar extending through or over the intercell partition in the direction of its length and over substantially its entire length.
Thus the battery of the present invention has all the advantages of the prior specification referred to above but does not include bipolar plates and thus does not suffer from the assembly disadvantages associated with such plates. The components for each cell can be assembled outside the battery container and the or each metallic bar can be formed either prior to or after insertion of the cell components into the container. The or each metallic bar serves a dual purpose in that it not only connects together all the plates of one polarity in one cell and the other polarity in the adjacent cell and thus constitutes two plate straps, but also connects together all these plates either over or through the intercell partition and thus constitutes an intercell connector.Not only are the current paths within each plate shortened by comparison with the paths in a battery in which the plates extend parallel to the intercell partitions but also the fact that al the lugs are adjacent to an intercell partition means that the intercell connection current paths are shortened also.
The invention also embraces a method of assembling such a battery, and according to a further aspect of the present invention such a method includes forming two or more cell packs comprising alternating substantially planar positive and negative electrodes interleaved with compressible fibrous absorbent material, the electrodes each having an upstanding lug and being arranged so that the lugs extend in lines of a single polarity each, inserting the cell packs into a substantially rectangular section container so that each adjacent pair of cell packs is separated by a respective substantially planar intercell partition and the electrodes extend substantially perpendicular to the adjacent intercell partition and the lines of lugs are adjacent the end walls of the container and the or each intercell partition, forming a continuous elongate metallic bar around each pair of lines of lugs of opposite polarity adjacent the or each intercell partition, each bar extending over or through the intercell partition in the direction of its length and over substantially its entire length and adding a amount of electrolyte to each cell pack such that there is substantially no free unabsorbed electrolyte.
As mentioned above, the or each metallic bar may be formed either before or after insertion of the cell packs into the container but preferably the or each metallic bar is formed after the partial insertion of the cell packs into the container. The electrolyte may be added at any appropriate stage of the assembly.
Each cell pack may be accommodated within a respective plastics bag, as is disclosed in British
Patent Specification No. 2062945 of the present applicants, in which case the container need have no fixed intercell partitions and each intercell partition is constituted by two thicknesses of plastics film comprising the walls of two adjacent plastics bags.
However, it is preferred that the or each intercell partition is integral with the container and terminates short of the lid, the associated metallic bar extending above it, since such intercell partitions can provide a reactive force to the compressive force on the cell packs whereas, of course, plastics bags can not. The or each metallic bar may be formed by any conventional method but this is preferably performed by inverting the container and dipping each pair of lines of lugs into a respective mold cavity in which molten metal is introduced either prior to or subsequent to the insertion of the lugs.
The separator material, which preferably comprises microfine glass fibres in sheet form as is described in more detail in British Patent Specification
No. 2062945, may be present in each cell in the form of a plurality of separate sheets between each pair of adjacent electrodes. Such a construction is however relatively expensive to assemble and it is therefore preferred that each cell contains a single sheet of separator material folded in a zig-zag manner so that its folds separate each pair of adjacent electrodes.
The method of assembly of this construction may therefore include folding a single strip of separator material for each cell pack in a zig-zag manner and inserting the electrodes of opposite polarity into the pockets formed in the sheet of separator material from opposite directions.
In an even more preferred construction the sheet of separator material is so folded that two thicknesses of separator material separate each pair of adjacent electrodes and the method may then include inserting the positive and negative electrodes in every alternate pocketformd in the sheet of separator material from the same direction which is found to facilitate the assembly procedure.
In a further embodiment of the invention each cell contains a single positive electrode member and a single negative electrode member, each electrode member being folded in a zig-zag manner so that all the electrodes of each polarity are integral with each other. Thus the method of assembly of this construction includes forming a sandwich from a single positive electrode member and a single negative electrode member separated by a single strip of separator material and folding the sandwich in a zig-zag manner.It will be appreciated that each electrode member requires a plurality of upstanding lugs so positioned that in the assembled cell the lugs will extend in two lines adjacent the two intercell partitions or the intercell partition and end wall of the container defining that cell and these may either be connected to the electrode members prior to or subsequent to their being folded or more preferably are integral with the electrode members at predetermined appropriate positions.
Further features and details of the present invention will be apparent from the following description of two specific embodiments which is given by way of example only with reference to the accompanying drawings, in which:
Figure 1 is a partly cut away perspective view of a six cell 12 volt lead acid automotive battery of recombination type in accordance with the present invention;
Figure 2 is a scrap perspective enlarged view of part of the battery of Figure 1;
Figure 3 is a partial diagrammatic perspective view of a modified construction of one cell pack;
Figure 4 is a diagrammatic scrap plan view illustrating the folding of the electrode members of the cell of Figure 3; and
Figure 5 is a diagrammatic plan view of the electrode members of the cell of Figure 3 prior to their being folded.
The battery seen in Figure 1 comprises a substantially rectangular section container 2 of polypropylene or the like material connected to which is a lid 4 of similar material. The external features of the battery form no part of the present invention and will therefore be described only briefly. The container 2 has two hold down ledges 6 on each end wall and four smaller hold down ledges 8 on each side wall by means of which the battery may be secured in position in a tray in a motor car. The lid 4 has two upstanding centrally disposed terminals 10 projecting through it and carries a handle 12 which is slidable between the position illustrated in which it may be used to carry the battery and a lower position in which its upper surface is flush with that of two upstanding formations 14 on the lid.In each corner of the lid is a further upstanding formation 16 in one of which there is a single vent 18.
Internally, the container 2 has five integral intercell partitions 20 which terminate short of the lid with the result that the battery has a gas or head space beneath the lid common to all the cells which may be vented to the atmosphere by the vent 18. The intercell partitions 20 and end walls of the container together define six cell compartments each of which contains a plurality of alternating positive electrode plates 22 and negative electrode plates 24. As seen more clearly in Figure 2, the plates 22 and 24 are separated by separator material comprising microfine glass fibres in a single sheet 26 which is folded in zig-zag form and accommodates a plate in each of its folds thereby separating adjacent plates from one another.
The plates extend perpendicular to the intercell partitions 20 and end walls of the container and thus have a length, when viewed from above, substantially less than their height, e.g. between one third and one fifth of their height. Each plate carries an upstanding lug 28 at one end and the plates are arranged so that in each cell there are two lines of lugs of the same polarity respectively adjacent the two intercell partitions or the intercell partition and end wall of the container defining that cell. Each pair of lines of lugs of opposite polarity adjacent to each intercell partition are connected by a respective rectangular section bar of lead or lead alloy 30 which extends closely above the associated intercell partition in the direction of its length and substantially over its full length.Each bar 30 thus connects together all the plates of one polarity in one cell to each other and also to all the plates of the opposite polarity in the adjacent cell. The two lines of lugs at each end of the container extending adjacent to its end walls are connected together by a respective plate strap 32 of lead or lead alloy which is connected to a respective terminal 10.
By virtue of the fact that the plates are of reduced size by comparison with those in a battery in which the plates extend parallel to the intercell partitions the current path within each plate is of reduced length and by virtue of the fact that all the plate lugs are immediately adjacent either to an intercell partition where they are connected to the lugs of opposite polarity in an adjacent cell or to an end wall of the container where they are connected to a battery terminal the intercell connection current paths and terminal connection current paths are of reduced length as compared with those in a battery in which the plates extends parallel to the intercell partitions.The internal resistance of the battery is thus lower than that of a conventional battery with the result that, all other things being equal, the battery can provide a higher rate discharge current and thus higher cranking power.
In use, the vent 18 is normally closed and any gas which is evolved within the battery during operation or charging is induced to recombine within the battery. If the charging rate should be excessively high the gas within the container, which can pass freely from cell to cell, may reach a pressure in excess of, e.g. 0.2 bar, and at such a predetermined pressure the vent 18 will open to reduce the pressure within the container.
The battery illustrated in Figures 1 and 2 is assembled by forming six cell packs comprising a sheet of separator material folded in a zig-zag manner, each of its folds accommodating a positive or negative plate. The number of plates is selected in accordance with the desired capacity of the battery but may typically be as high as sixty plates per cell.
The plate packs are then partially inserted into their respective cell compartments and the battery is then inverted and the lines of lugs dipped into mould cavities containing molten lead or lead alloy to form the metalic bars 30 and plate straps 32 in the conventional manner. By virtue of the fact that the cell packs are placed into the container under a certain compessive force for the reason explained above, inversion of the battery does not result in the cell packs falling out of the container. The compressive force exerted on the cell packs is provided by the end walls of the container and the intercell partitions which are thus in tension. They can easily withstand the tensional force to which they are subjected and thus the end walls of the container do not require special reinforcement.The cell packs are then pushed home into the container and the lid is secured to it in any conventional manner, e.g. by hot plate welding. At any appropriate stage in the method, e.g. immediately before connection of the lid, electrolyte is added to each cell in an amount insufficient to saturate the plates and separators.
In the modified embodiment illustrated in Figures 3, 4 and 5, each cell pack is made up from a single positive electrode member 30 and a single negative electrode member 32 which are overlaid with a single strip of separator material 26 between them to form a sandwich. Each electrode member has a plurality of integral upstanding lugs 28 spaced apart by a distance substantially equal to the width of the cell compartment into which the assembled cell pack is to be inserted. The lugs on the positive and negative electrode members are offset from one another by half a pitch. The sandwich is then folded in a zig-zag manner, as shown in Figure 4, so that the positive and negative lugs are positioned adjacent the folds and lie in two straight lines. when the folding is complete the cell pack may be surrounded by a band 34 which holds it together and places it under the desired compressive stress. The cell packs are then inserted into the container and the method proceeds as before.
