BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a connecting structurefor exteriorly connecting battery cells which is weldless andresistant to oxidation and can provide a high conductivityconnection among many battery cells.
Description of the Prior Art
The existing high power battery assemblies are mainlyconstructed by connecting multiple battery cells in series,parallel or series-parallel through connecting sheets. Thepositive and the negative electrode terminals of therespective battery cells are normally made of the nickel ornickel-plated metal, and so are the connecting sheets becauseof the advantage that nickel is resistant to oxidation andhence more secure for long services. As for the battery cells11 in a conventional battery assembly, as shown in Figs. 1 and2, no matter in serial or parallel configuration, they are allconnected by a connecting sheet 10 welded to the metallicelectrode terminals 12 of the battery cells 11 through severalwelding spots 13 which could reduce the external contactresistance of the battery assembly.
It is to be noted that, the above connecting technologyfor conventional battery cell can electrically connect twobattery cells through nickel connecting sheets by spotwelding; but, it suffers from many disadvantages such as: 1. After being used for a long time, the nickelconnecting sheets will still be eventually oxidized orcontaminated with foreign matters, thus increasing theelectric resistance of the connecting sheets.
2. The nickel connecting sheets are connected to theelectrode terminals of the battery cells through the weldingspots typically in small contact areas, resulting in highcontact resistance, thus causing increase in temperature ofthe electrode terminals of the battery cells as well as thewelding spots plus extra power losses of the battery cellsduring the recharging or discharging processes.
3. The nickel connecting sheets are expensive; and, thewelding process is time-consuming and labor intensive, makingthe conventional battery connecting technology uneconomic.
Hereafter, the present invention has arisen to mitigateand/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary objective of the present invention is toprovide a connecting structure for exteriorly connectingbattery cells in accordance with the present invention mainlyutilizes at least one connecting graphite alloy block servingas a bridge for connecting two battery cells in series orparallel. In the present invention, the connecting graphitealloy block is connected to the electrode terminals of thebattery cells in a direct contact manner to realize a highlyconductive connection without utilization of the conventionalwelding procedures. Furthermore, the connecting graphite alloyblock is less-expensive compared to nickel so that theproduction cost can be greatly reduced.
The secondary objective of the present invention is toprovide a connecting structure for exteriorly connectingbattery cells which mainly utilizes a connecting graphitealloy block to electrically connect two battery cells inseries or parallel. The connecting graphite alloy block by itself is resistant to oxidation. After close mutual contact,the connecting graphite alloy block and the positive, thenegative electrode terminals of the battery cells will start aprocess of dissolving in each other, namely the process ofcarbon particles of the connecting graphite alloy blocksubstituting for the foreign matters on the surfaces of thenegative and the positive electrode terminals of the batterycells so as to fill the voids in the metallic surfaces of thenegative and the positive electrode terminals of the batterycells until forming a carbon-nickel miscible alloy, thusensuring a smooth large-current discharge due to reduction ofthe external connection resistance.
In order to achieve the above objectives, a connectingstructure for exteriorly connecting battery cells in series inaccordance with the present invention comprises: a firstbattery cell which is exteriorly provided with a positiveelectrode terminal and a negative electrode terminal both madeof nickel-plated metal and served as power output terminals ofthe first battery cell; at least one connecting graphite alloyblock which is made of a graphite alloy selected from a groupconsisting of silver graphite, copper graphite, and silver-copper graphite and connected to the positive electrodeterminal of the first battery cell; and a second battery cellwhich is exteriorly provided with a positive electrodeterminal and a negative electrode terminal both made ofnickel-plated metal and served as power output terminals ofthe second battery cell. The negative electrode terminal ofthe second battery cell is connected to the connectinggraphite alloy block so as to connect the first battery celland the second battery cell in series.
Furthermore, a connecting structure for exteriorlyconnecting battery cells in parallel comprises: a firstbattery cell which is exteriorly provided with a positiveelectrode terminal and a negative electrode terminal both madeof nickel-plated metal and served as power output terminals ofthe first battery cell; at least one first connecting graphiteblock which is made of a graphite alloy selected from a groupconsisting of silver graphite, copper graphite, and silver-copper graphite and connected to the positive electrode terminal of the first battery cell; a second battery cellwhich is exteriorly provided with a positive electrodeterminal and a negative electrode terminal both made ofnickel-plated metal and served as power output terminals ofthe second battery cell, the positive electrode terminal ofthe second battery cell is connected to the first connectinggraphite block; and at least one second connecting graphiteblock which is made of a graphite alloy selected from a groupconsisting of silver graphite, copper graphite, and silver-copper graphite and connected to the negative electrodeterminal of the first battery cell and the negative electrodeterminal of the second battery cell so as to connect the firstand the second battery cells in parallel.

Thereby, the first and the second battery cells 20, 40 areconnected in series.
In addition, the negative electrode terminal 22 of thefirst battery cell 20 and the positive electrode terminal 41of the second battery cell 40 each can be connected to agraphite terminal 401, 402 as a final power output terminalthereof. Each of the graphite terminals 401, 402 is interiorlyprovided with a wire 403, 404 serving as a power output wirethereof .
Further referring to Fig. 4, when two battery cells areconnected in parallel, a first connecting graphite alloy blockand a second connecting graphite alloy block are employed formaking electrical connection between the first battery celland the second battery cell in parallel in order to improvethe electric conductivity between the first and the secondbattery cells.
The first battery cell 60 is a cylindrical battery celland exteriorly provided on both ends thereof with a positiveelectrode terminal 61 and a negative electrode terminal 62both being made of nickel-plated metal and served as poweroutput terminals of the first battery cell 60.
The first connecting graphite alloy block 70 is made of agraphite alloy selected from a group consisting of silvergraphite (silver-carbon alloy), copper graphite (copper-carbonalloy), and silver-copper graphite (silver-copper-carbonalloy). The first connecting graphite alloy block 70 iselectrically connected to the positive electrode terminal 61of the first battery cell 60 in a close contact manner.

The aforementioned is the summary of the positional andstructural relationship of the respective components of thepreferred embodiment in accordance with the present invention.
As for the function of the present invention, the presentinvention mainly utilizes connecting graphite alloy blocks todirectly connect the battery cells in series or parallelwithout utilization of the conventional welding procedures,thus improving the connective conductivity and reducing theproduction costs because of elimination of the conventionalwelding procedure.
It is to be noted that, referring to Fig. 5-1, thenegative electrode terminal 22 and the positive electrodeterminal 41 of the first and the second battery cells 20, 40are both made of the nickel-plated metal, the positive and thenegative electrode terminals 41, 22 each are adhered withforeign matters 500 or oxides 200 on a surface thereof, theforeign matters 500 or oxides 200 will increase the connectionresistance during the discharging process of the first and thesecond battery cells 20, 40 while reducing the dischargingpower efficiency of the battery cells. Referring to Fig. 3 andFig. 5-2, showing how to realize high conductivity connectionbetween battery cells, the connecting graphite alloy block 30is electrically connected to the positive and the negativeelectrode terminals 41, 22 of the first and the second batterycells 20, 40; the connecting graphite alloy block 30 by itselfis resistant to oxidation, and the connecting graphite alloy block 30, and the positive, the negative electrode terminals41, 22 of the first and the second battery cells 20, 40 willdissolve into each other after mutual contact, that is, thecarbon particles 600 of the connecting graphite alloy block 30will substitute for the foreign matters 500 or oxides 200 onthe positive and the negative electrode terminals 41, 22 madeof the nickel-plated metal to fill in the voids in thepositive and the negative electrode terminals 41, 22, and thenform a carbon-nickel miscible alloy, thereby improving theconnective conductivity among the connecting graphite alloyblock 30, the first battery cell 20 and the second batterycell 40. In other words, after the battery assembly inaccordance with the present invention is switched on, electriccurrent will flow between the first battery cell 20, theconnecting graphite alloy block 30 and the second battery cell40 smoothly through the connecting structure for exteriorlyconnecting battery cells of the present invention withoutbeing affected by the inherent resistance caused by the oxides200 or the foreign matters 500, thus not only reducing theexternal connection resistance between the first and thesecond battery cells 20, 40, but facilitating the successfuldischarging of the first and the second battery cells 20, 40.
Referring to Fig. 6, when plural battery cells 301 areconnected in series, parallel or series-parallel to constructa high-power battery assembly 300 through plural connectinggraphite alloy blocks 302 of the present invention, since theconnecting graphite alloy blocks 302 will dissolve into thepositive and the negative electrode terminals both being madeof nickel-plated metal to improve the connective conductivitybetween the respective battery cells 301, the power loss ofthe external resistance of the battery assembly 300 iscomparably less than that of the conventional battery assemblyin which the battery cells are connected through nickel sheetsby spot welding. Evidently, the external resistance of thebattery assembly which is constructed by making use of theconnecting technology of present invention is relativelysmall, and the contact resistance of the battery cells 301 andthe connecting graphite alloy blocks 302 is reduced whichresulting in reduction of working temperature. In other words, the discharging losses of the battery assembly which isconstructed by making use of the technology of the presentinvention are reduced, and the power of the battery assemblycan be delivered smoothly in high efficiency.
In addition to the cylindrical metal-cased battery cells,as shown in Fig. 7, the present invention is also applicableto coffee-bagged battery cells in aluminum foils. The positiveand the negative electrodes of the coffee-bagged battery cellsare normally stamp-formed into electrode tabs made of nickel-plated metal, as shown in Fig. 7. When two coffee-baggedbattery cells 101, 102 are connected in series, a connectinggraphite alloy block 30 is employed to electrically connectthe positive and the negative electrode tabs 105, 106 of thetwo battery cells 101, 102, respectively. It is to be notedthat, the metal-cased battery cells are only different inshape to the coffee-bagged battery cells, that is, they areindifferent in electrical connection effects. In other words,the technology of the present invention is independent to theinternal configuration of the battery cells as long as thepositive and the negative electrode terminals of the batterycells are made of the nickel-plated metal, hence, the batterycells can be connected through the connecting graphite alloyblocks of the present invention to realize the highconductivity external connection of the battery cells.
While we have shown and described various embodiments inaccordance with the present invention, it is comprehensive tothose skilled in the art that further embodiments may be madewithout departing from the scope of the present invention.
