Definitions

  • the present invention generally relates to an electrochemical cell construction. More particularly, the present invention relates to the containers used for an electrochemical cell, such as an alkaline cell.
  • Figure 1 shows the construction of a conventional C sized alkaline cell 10.
  • cell 10 includes a cylindrically shaped can 12 having an open end and a closed end.
  • Can 12 is preferably formed of an electrically conductive material, such that an outer cover 11 welded to a bottom surface 14 at the closed end of can 12 serves as an electrical contact terminal for the cell.
  • Cell 10 further typically includes a first electrode material 15, which may serve as the positive electrode (also known as a cathode).
  • the first electrode material 15 may be preformed and inserted into can 12, or may be moulded in place so as to contact the inner surfaces of the can 12.
  • first electrode material 15 will typically include MnO 2 .
  • a separator 17 is inserted into the space defined by first electrode 15. Separator 17 is preferably a non-woven fabric. Separator 17 is provided to maintain a physical separation of the first electrode material 15 and a mixture of electrolyte and a second electrode material 20 while allowing the transport of ions between the electrode materials.
  • an electrolyte is dispensed into the space defined by separator 17, along with the mixture 20 of electrolyte and a second electrode material, which may be the negative electrode (also known as the anode).
  • the electrolyte/second electrode mixture 20 preferably includes a gelling agent.
  • mixture 20 is formed of a mixture of an aqueous KOH electrolyte and zinc, which serves as the second electrode material. Water and additional additives may also be included in mixture 20.
  • collector assembly 25 serves to support the collector assembly in a desired orientation prior to securing it in place.
  • an outer cover 45 is placed over collector assembly 25.
  • Collector assembly 25 is secured in place by radially squeezing the can against collector assembly 25.
  • the end edge 13 of can 12 is crimped over the peripheral lip of collector assembly 25, thereby securing outer cover 45 and collector assembly 25 within the end of can 12.
  • one function served by collector assembly 25 is to provide for a second external electrical contact for the electrochemical cell. Additionally, collector assembly 25 must seal the open end of can 12 to prevent the electrochemical materials therein from leaking from this cell. Additionally, collector assembly 25 must exhibit sufficient strength to withstand the physical abuse to which batteries are typically exposed.
  • collector assembly 25 may allow internally generated hydrogen gas to permeate therethrough to escape to the exterior of the electrochemical cell. Further, collector assembly 25 should include some form of pressure relief mechanism to relieve pressure produced internally within the cell should this pressure become excessive. Such conditions may occur when the electrochemical cell internally generates hydrogen gas at a rate that exceeds that at which the internally generated hydrogen gas can permeate through the collector assembly to the exterior of the cell.
  • the collector assembly 25 shown in Figure 1 includes a seal 30, a collector nail 40, an inner cover 44, a washer 50, and a plurality of spurs 52.
  • Seal 30 is shown as including a central hub 32 having a hole through which collector nail 40 is inserted.
  • Seal 30 further includes a V-shaped portion 34 that may contact an upper surface 16 of first electrode 15.
  • Seal 30 also includes a peripheral upstanding wall 36 that extends upward along the periphery of seal 30 in an annular fashion.
  • Peripheral upstanding wall 36 not only serves as a seal between the interface of collector assembly 25 and can 12, but also serves as an electrical insulator for preventing an electrical short from occurring between the positive can and negative contact terminal of the cell.
  • Inner cover 44 which is formed of a rigid metal, is provided to increase the rigidity and support the radial compression of collector assembly 25 thereby improving the sealing effectiveness. As shown in Figure 1, inner cover 44 is configured to contact central hub portion 32 and peripheral upstanding wall 36. By configuring collector assembly 25 in this fashion, inner cover 44 serves to enable compression of central hub portion 32 by collector nail 40 while also supporting compression of peripheral upstanding wall 36 by the inner surface of can 12.
  • Outer cover 45 is typically made of a nickel-plated steel and is configured to extend from a region defined by the annular peripheral upstanding wall 36 of seal 30 and to be in electrical contact with a head portion 42 of collector nail 40. Outer cover 45 may be welded to head portion 42 of collector nail 40 to prevent any loss of contact. As shown in Figure 1, when collector assembly 25 is inserted into the open end of can 12, collector nail 40 penetrates deeply within the electrolyte/second electrode mixture 20 to establish sufficient electrical contact therewith. In the example shown in Figure 1, outer cover 45 includes a peripheral lip 47 that extends upwardly along the circumference of outer cover 45.
  • peripheral upstanding wall 36 of seal 30 By forming peripheral upstanding wall 36 of seal 30 of a length greater than that of peripheral lip 47, a portion of peripheral upstanding wall 36 may be folded over peripheral lip 47 during the crimping process so as to prevent any portion of the upper edge 13 of can 12 from coming into contact with outer cover 45.
  • Seal 30 is preferably formed of nylon.
  • a pressure relief mechanism is provided for enabling the relief of internal pressure when such pressure becomes excessive.
  • inner cover 44 and outer cover 45 are typically provided with apertures 43 that allow hydrogen gas to escape to the exterior of cell 10.
  • the mechanism shown includes an annular metal washer 50 and a plurality of spurs 52 that are provided between seal 30 and inner cover 44. Each spur 52 includes a pointed end 53 that is pressed against a thin intermediate portion 38 of seal 30.
  • Spurs 52 are biased against the lower inner surface of inner cover 44 such that when the internal pressure of cell 10 increases and seal 30 consequently becomes deformed by pressing upward toward inner cover 44, the pointed ends 53 of spurs 52 penetrate through the thin intermediate portion 38 of seal 30 thereby rupturing seal 30 and allowing the escape of the internally-generated gas through apertures 43.
  • a label is applied over the external surface of the battery can, for example a shrink-wrap film or an adhesive sticker that contains or supports visual information on or in a film or other label substrate.
  • the measured external and internal volumes for several batteries that were commercially available at the priority date of this application are listed in the tables shown in Figures 2A and 2B.
  • the tables list the volumes (cc) for D, C, AA, and AAA sized batteries.
  • the collector assembly volume and the percentage of the total cell volume that constitutes the collector assembly volume is provided in Figure 2B for those commercially available batteries listed in Figure 2A.
  • Also provided in Figure 2A is a percentage of the total cell volume that constitutes the internal volume that is available for containing the electrochemically active materials.
  • the “total cell volume” includes all of the volume, including any internal void spaces, of the battery.
  • the total volume ideally includes all of the cross-hatched area as shown in Figure 3A.
  • the “internal volume” of the battery is represented by the cross-hatched area shown in Figure 3B.
  • the "internal volume”, as used herein, is that volume inside the cell or battery that contains the electrochemically active materials as well as any voids and chemically inert materials (other than the collector nail) that are confined within the sealed volume of the cell.
  • Such chemically inert materials may include separators, conductors, and any inert additives in the electrodes.
  • the term “electrochemically active materials” includes the positive and negative electrodes and the electrolyte.
  • the “collector assembly volume” includes the collector nail, seal, inner cover, washer, spurs, and any void volume between the bottom surface of the negative cover and the seal
  • the “container volume” includes the volume of the can, label, negative cover (outer cover 45), void volume between the label and negative cover, positive cover, and void volume between the positive cover and can (shown by the cross-hatched area in Figure 3D). If the label extends onto and into contact with the negative cover, the void volume present between the label and negative cover is included in the container volume, and therefore is also considered as part of the total volume. Otherwise, that void volume is not included in either of the container volume or the total volume.
  • the sum total of the "internal volume”, “collector assembly volume”, and “container volume” is equal to the “total volume”. Accordingly, the internal volume available for electrochemically active materials can be confirmed by measuring the collector assembly volume and container volume and subtracting the collector assembly volume and the container volume from the measured total volume of the battery.
  • the present invention provides a battery comprising a can and a label, wherein the label comprises a print layer that is directly applied onto the can.
  • the present invention provides a battery that comprises a can for containing electrochemically active materials including positive and negative electrodes and an electrolyte, and a label printed directly on an exterior surface of the can.
  • the present invention provides a method of preparing a battery having a label on a can, comprising directly applying a print layer onto the can.
  • the present invention provides a method of assembling a battery including the steps of forming a can having an open end and a closed end, forming an outer cover, dispensing electrochemically active materials in the can, sealing the outer cover across the open end of the can with a layer of electrical insulation provided therebetween, and printing a label directly on the exterior surface of the can.
  • the diameter of the can may be correspondingly increased to allow a significant increase in the internal volume of the battery, while maintaining a predetermined total outside diameter.
  • a further advantage is that the cell may be simpler to manufacture and that require less materials, thereby possibly having lower manufacturing costs.
  • Figure 1 is a cross section of a conventional C sized alkaline electrochemical cell
  • Figure 2A is a table showing the relative total battery volumes and internal cell volumes available for electrochemically active materials, as measured for those batteries that were commercially available at the priority date of this application;
  • Figure 2B is a table showing the relative total battery volumes and collector assembly volumes as measured for those batteries that were commercially available as provided in Figure 2A;
  • Figures 3A-3D are cross sections of a conventional C sized alkaline electrochemical cell that illustrate the total battery and various component volumes;
  • Figure 4A is a table showing the calculated total and internal cell volume for various batteries; and Figure 4B is a table showing the calculated total volume and collector assembly volume for various batteries.
  • a primary objective of the present invention is to increase the internal volume available in a battery for containing the electrochemically active materials.
  • a label may be lithographed directly onto the exterior surface of the battery can. By lithographing the label directly onto the exterior of the can, the internal volume of the cell may be increased since one does not have to account for the thickness of the label substrate to construct a cell that meets the ANSI or other exterior size standards.
  • the inventive battery construction includes a directly applied print label, rather than the label substrates currently used.
  • directly is meant that no label substrate is present between the print layer and the external surface of the battery can.
  • Current label substrates have thicknesses on the order of 75 ⁇ m (3 mils). Because such label substrates overlap to form a seam running along the length of the battery, these conventional labels effectively add about of 250 ⁇ m (10 mils) to the diameter and of 330 ⁇ m (13 mils) to the crimp height of the battery.
  • the battery can must have a diameter that is selected to accommodate the thickness of the label seam in order to meet the ANSI or other size standards.
  • the diameter of the can may be correspondingly increased approximately of 250 ⁇ m (10 mils). Such an increase in the diameter of the can significantly increases the internal volume of the battery.
  • FIGS 4A and 4B show volumes of various different types of battery constructions that are more fully disclosed in US 60/102,951 filed 2 October 1998 and US 60/097,445 filed 21 August 1998. All of the batteries listed in the tables of Figures 4A and 4B, with the exception of the beverage can constructions, include substrate labels.
  • the internal volume of the batteries with substrate labels could be further increased, for example by 2 percent (1.02 cc) for a D sized battery, 2.6 percent (0.65 cc) for a C sized battery, 3.9 percent (0.202 cc) for an AA sized cell, and 5.5 percent (0.195 cc) for an AAA sized battery, if the labels were printed directly on the exterior of the can.
  • Labels may also be printed on the can using transfer printing techniques in which the label image is first printed on a transfer medium and then transferred directly onto the can exterior. Distorted lithography may also be used whereby intentionally distorted graphics are printed on flat material so as to account for subsequent stress distortions of the flat material as it is shaped into the tube or cylinder of the cell can.
  • the exterior surface of the can Prior to printing the lithographed label, the exterior surface of the can is preferably cleaned. To enhance adherence of the print to the can, a base coat of primer may be applied to the exterior surface of the can. The print layer is then applied directly on top of the base coat on the can by known lithographic printing techniques.
  • the label may further comprise an electrically insulating overcoat.
  • a varnish overcoat is preferably applied over the print layer to cover and protect the print layer, and also to serve as an electrically insulating layer.
  • the printed label may be cured with the use of high temperature heating or ultraviolet radiation techniques.
  • the thickness of the label may be significantly reduced compared with a conventional label on a substrate, to a maximum thickness of approximately 13 ⁇ m (0.5 mils).
  • the printed label has a base coat layer of a thickness in the range of about 2.5 to 5 ⁇ m (0.1 to 0.2 mil), a print layer of a thickness of approximately 2.5 ⁇ m (0.1 mil), and a varnish overcoat layer of a thickness in the range of about 2.5 to 5 ⁇ m (0.1 to 0.2 mil).
  • the present invention has been described above as having primary applicability to alkaline batteries, it will be appreciated by those skilled in the art that similar benefits may be obtained in batteries utilising other electrochemical systems.
  • the inventive constructions may be employed in primary systems such as carbon-zinc and lithium based batteries and in rechargeable batteries, such as NiCd, metal hydride, and Li based batteries.
  • the present invention has been described above in connection with cylindrical batteries, the present invention may be employed in constructing cells of any shape that can support a label, for example prismatic cells.
  • the total battery volume, collector assembly volume, and internal volume available for electrochemically active material for each battery are determined by viewing a Computer Aided Design (CAD) drawing, a photograph, or an actual cross section of the battery which has been encased in epoxy and longitudinally cross- sectioned.
  • CAD Computer Aided Design
  • the use of a CAD drawing, photograph, or actual longitudinal cross section to view and measure battery dimensions allows for inclusion of all void volumes that might be present in the battery.
  • To measure the total battery volume the cross-sectional view of the battery taken through its central longitudinal axis of symmetry is viewed and the entire volume is measured by geometric computation.
  • the cross-sectional view of the battery taken through its central longitudinal axis of symmetry is viewed, and the components making up the internal volume, which includes the electrochemically active materials, void volumes and chemically inert materials (other than the collector nail) that are confined within the sealed volume of the cell, are measured by geometric computation.
  • the cross- sectional view of the battery taken through its central longitudinal axis of symmetry thereof is viewed, and the components making up the collector assembly volume, which include the collector nail, seal, inner cover, and any void volume defined between the bottom surface of the negative cover and the seal, are measured by geometric computation.
  • the container volume may likewise be measured by viewing the central longitudinal cross section of the battery and computing the volume consumed by the can, label, negative cover, void volume between the label and negative cover, positive cover, and void volume between the positive cover and the can.
  • the volume measurements are made by viewing a cross section of the battery taken through its longitudinal axis of symmetry. This provides for an accurate volume measurement, since the battery and its components are usually axially symmetric.
  • the battery was first potted in epoxy and, after the epoxy solidified, the potted battery and its components were ground down to the central cross section through the axis of symmetry. More particularly, the battery was first potted in epoxy and then ground short of the central cross section. Next, all internal components such as the anode, cathode, and separator paper were removed in order to better enable measurement of the finished cross section.
  • the potted battery was then cleaned of any remaining debris, was air dried, and the remaining void volumes were filled with epoxy to give the battery some integrity before completing the grinding and polishing to its centre.
  • the battery was again ground and polished until finished to its central cross section, was thereafter traced into a drawing, and the volumes measured therefrom.
  • the cross-sectional view of the battery was used to make a drawing.
  • a Mitutoyo optical comparator with QC-4000 software was used to trace the contour of the battery and its individual components to generate a drawing of the central cross section of the battery. In doing so, the battery was securely fixed in place and the contour of the battery parts were saved in a format that could later be used in solid modelling software to calculate the battery volumes of interest.
  • the drawing may be adjusted to compensate for any battery components that are not aligned exactly through the centre of the battery. This may be accomplished by using the measurements that were taken from the battery before cross sectioning the battery and those measurements taken from the disassembled identical battery.
  • the diameter and length of the current collector nail, and overall outside diameter of the battery can be modified to profile the drawing more accurately by adjusting the drawing to include the corresponding known cross-sectional dimensions to make the drawing more accurate for volume measurements.
  • the detail of the seal, cover, and crimp areas were used as they were drawn on the optical comparator.
  • the drawing was imported into solid modelling software.
  • a solid three-dimensional volume representation was generated by rotating the contour of the cross section on both the left and right sides by one-hundred- eighty degrees (180°) about the longitudinal axis of symmetry. Accordingly, the volume of each region of interest is calculated by the software and, by rotating the left and right sides by one-hundred-eighty degrees (180°) and summing the left and right volumes together an average volume value is determined, which may be advantageous in those situations where the battery has non-symmetrical features.
  • the volumes which include any non-symmetrical features can be adjusted as necessary to obtain more accurate volume measurements.
  • the internal volume of the batteries with substrate labels could be further increased 2 percent (1.02 cc) for a D sized battery, 2.6 percent (0.65 cc) for a C sized battery, 3.9 percent (0.202 cc) for an AA sized cell, and 5.5 percent (0.195 cc) for an AAA sized battery, if the labels were printed directly on the exterior of the can.

Abstract

La présente invention concerne une batterie comprenant une enveloppe et une étiquette présentant une couche d'impression directement imprimée sur l'enveloppe. Par ailleurs, cette invention concerne un procédé de fabrication d'une batterie présentant une étiquette sur l'enveloppe, ce procédé consistant à appliquer directement une couche d'impression sur l'enveloppe. En outre, on peut appliquer une couche d'apprêt directement sous la couche d'impression, et une couche d'isolation électrique sur la couche d'impression. Puisque la couche d'impression est directement appliquée, sans substrat à étiquette, on peut réduire l'épaisseur de l'étiquette, permettant ainsi une augmentation correspondante du diamètre de l'enveloppe de la batterie et fournissant un volume interne disponible pour les matériaux électrochimiquement actifs.
