ABSTRACT
Terminal contact is made between an electrode in an electrochemical cell and the external terminal therefor by capture of an electrically conductive portion of said electrode within or by a member of a compressively formed seal of the cell.
Description
~ lis invention relates to terminal contacts between electrodes and terminals therefor and particularly for spirally wound electrodes in non-aqueous aerosol type cell containers.
Terminal contact between an electrode and the portion of the cell container which is to function as the terminal therefor, particularly in non-aqueous cells has generally been accomplished by several well recognized methods, the most common of whlch is by welding of the electrode directly to the terminal or via an intermed:Lary eLectrlcally conductive tab or wire. Another common method ls by direct compressive contact between the electrode material and a portion of the metal cell contalner and in the case of certain metal electrodes such as lithium the forces used to effect such compressive contact actually result in a cold weld. In cells having spirally wound configurations such compressive contact is difficult to reliably achieve and accordingly weld connections have been utilized in such cells for reliability. However, such welding for terminal connections requires additional manufacturing steps thereby increasing costs. Furthermore, weld sites are particularly prone to de~rimental corrosion.
It is an object of the present invention to provide a method for providing an economical and reliable electrode-terminal connection in a compressively sealed cell and the cell so made.
It is a further object of the present invention to provide such method in the constructlon of non-aqueous electrochemical cells in an aerosol type structure and having a spirally wound electrode structure.
These and other objects, features and advantages of the present invention will become more evident from the following discussion and the drawings (illustrative and not to scale) in which:
Figure 1 depicts a preferred method for cutting electrodes ln a shape suitable for use in the present invention;
~& ~`t~-' ~. ~ 3 ~
Figure 2 is an isometric view durlng the winding of the cell electrodes including the cut electrodes shown in Figure 1, into a spirally wound structure;
Figure 3 ls a sectioned elevation view of a cell container having the spirally wound cell structure therein prior to sealing of the cell;
Figure 4 is an enlarged sectioned view of the electrode extension being caught by the curling of the end of the cell container; and Figure 5 is a partial sectioned elevation view of the sealed cell.
Generally, the present invention comprises a method for mechanically effecting a reliable electrode to terminal electrical connectlon in an electrochemical cell, wlthout the necessity of welding and the cell having such electrical connection. The electrode, particularly the cathode, which usually presents ~reater difficulty ln malcing welding connections, is initially sized and cut or alternatively made initially larger such that a portion thereof extends beyond the generally spirally wound electrode structure. The electrode is either metallic or contains a metallic substrate which is electrically conductive and such extension is similarly metallic or metal containing in order to effect Lhe requisite terminal connection of the present invention. The extension of the electrode is positioned such that when the electrode structure is placed within the generally cylindrical cell container prior to sealing, the extension is proximate with the open end of the cell container or sealing area. The extension is further positioned such that upon the inward (such as an aerosol type seal) curling of the cell container end said extension is caught and compressively held between the curled end and the container wall to effect a positive electrical connection between the electrode and the container. When the container is sealed by the positioning and crimping of a top member on the curled end the electrical connection is further mechanically reinforced. In an alternative but less preferred embodiment the electrode extension is caught between the curled end and the cell top member. Care must however be taken that the electrode extension (such as those having expanded metal substrates therein) not perforate the insulation between the curled end and the top member and that the electrode extension does not substantially affect the integrity of the seal between the curled end and top member. Since the present invention requires that the container end be curled inwardly to effe,ct the requlsite terminal connection it is of particular applLcabllity in cell containers of the aerosol type conEiguration as shown in ~.S.
Patent Nos. 4,136,43~ and 4,052,537 which are specifically constructed with such inwardly curled ends. Though it is preferred that the extension be integral with the electrode for simplicity, such extension may also bc an initially separate element attached to the electrode.
With specific reference to the drawings, Figure 1 depicts a cathode master roll 1 which is slit into cathode strips 2 for use $n a splrally wound cell configuration. ~ach of the ca~hode strips 2 includes an integral extension or jog 3 which is located at a predetermined position near the outer end (when wound) of the cathode strip 2. The slitting of the cathode master roll 1 in thls manner provides the integral extension 3 without the necessity for additional steps and further minimizes waste.
Each cathode strip 2 is comprised o~ a compressed powder (cathode active e.g. MnO2 or inactive e.g. carbon or graphite) depending on the particular cell system) on a metal substrate such as of expanded metal.
The extension 3 may either have the powder retained thereon or have it removed to expose the expanded metal substrate which provides the requisite electrlcally conductive connection.
The length of jog 3 may be the length of the cathode but is preferably predetermined as being less than the circumference of the cell container end prior to sealing, in order to avoid overlap of the ~og 3 on itself whereby mechanlcal contact may be affected. More preferably, since ~og 3, in the slitting configuration shown, causes some loss in cathode capacity it is preferably further minimized ln length with about one third of the circumference providing ~ t3 ~
good mechanical contact with minimal capacity loss. The height of jog 3 is similarly predetermined relative to the cell container end whereby it is situated adjacent and preferably slightly below said end when the electrode is placed in the cell container prior to sealing.
After slitting, the cathode strips 2 are spirally wound into the "jelly roll" cell electrode structure configurat~on 10 shown in Pigure 2 with layers oE separator material 4 and anode material 5 such as of lithium with ~og 3 extending beyond the "~elly roll" structure.
The spirally wound electrode structure 10 is then placed w-lthin metal cell container 6 which is then necked as shown in Figure 3 with cathode extension 3 being adjacen~ the end portion 7 of the cell container 6 and slightly below the edge of said end portion. Such necking is however totally optlonal and dependent upon the cell container configuration desired. Jog 3 is preferably positioned in the cathode at a predetermined site such that upon such necking of cathode container 6 it is vertically adjacent end portion 7. Without necking of the cell container such jog i5 generally at the outer end of cathode strip 2 The end portion 7 is then curled inwardly, as part of the cell seallng procedure, and also thereby fixedly captures the cathode extension 3 by compression between the curled end 7 and the container wall 3 as shown in Figure 4 in expanded detail. It is preferred that extension 3 be below the edge of end portion 7 and adjacent thereto in order to facilitate this "capture" of extension 3 by end portion 7 being curled therearound during the cell sealing procedures-Since spirally wound cathodes are generally constructed with metallic substrates (generally of expanded nickel, aluminum or stainless steel in non-aqueous cells) the edge of end portion 7 preferably bites through the cathode material 9 such as carbon, manganese dioxlde or other powdered material and makes positive mechanical and electrical contact with metal substrate 11, if the cathode material had not already been removed from extension 3. Though the edge of end portion 7 is shown as making such electrical contact, a tight curl may be similarly effective in both holding the cathode extension and effecti.ng electrical contact, particularly wherein cathode material 9 was previously removed from extension 3.
The cell contalner 6 is compressively sealed with container top 17 as shown in Figure 5 wlth an aerosol type expandlng collet crimp 13 which compresses the curled end 7 with captured cathode exten6ion 3 to further enhance both mechanical and electrical terminal contact between the cathode and the cell container 6 which functions thereby as the cathode terminal of the cell. Container top 12 is electrically insulated from cell container 6 by sealing gasket 14 such as polytetrafluoroethylene, or other inert polyhalogenated polymers, polyolefins such as polypropylene and polyethylene, nylon, polyurethane, neoprene and the like with the particular sealing gasket material being generally determined by compat-ibility with cell components. The sealing gasket 14 serves the dual function in providing an hermetic seal for the cell and also the electrical insulation thereof.
Such seal provides hermeticity as particularly required for non-aqueous cell which, for the most part, have had glass to metal or ceramic seals. In an alternative embodiment of the present -lnvention the cathode extension 3 may be entrapped as part of the seal ltselE if positioned between sealing gasket 14 and the curled end 7 during the sealing procedure.
However, since the cathode material itself does not provide a good sealing substrate there must be sufficient residual curl - sealing gasket interface to provide the requisite sealing of the cell.
While the configuration of the electrodes in the most preferred embodiment of the present invention is the spirally wound one, the present invention is similarly applicab]e to any configuration having plate or layer type electrodes wherein such electrodes may have integral extensions suitable for the capture for electrical contact of the present invention.
Similarly while the electrode capture oE the present invention -ls of greatest utility with catho~es it is equally applicable to anodefi.
The present invention is applicable to cells having any electrochemical system but is most useful in non-aqueous electrochemical cells having pressurized or non-pressurized components such as Li/SO2, Li/SOCl~ and Li/MnO2 cells wherein reduction of cost without sacriflce of contruction integrity i6 of increasing importance in bringing such cells to general commercial applicability.
It is understood that the embodiment described and shown in the drawings is for illustrative purposes and that changes in cell components and configuration may be made without departing from the scope of the present invention as defined in the following claims.
