~ ith the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several views illustrated in the accompanying drawings.
IN T~iE DRA~INGS:
Figure l is a fragmentary side elevational view of a power module formed in accordance with this invention, parts of the casing being broken away and shown in section.
Figure 2 is a top plan view of the power module of Figure l, with upper portions of the casing being broken away and shown in section so as to illustrate the position of the flexible side walls within the casing.
Figure 3 is a transverse vertical sectional view taken generally along the line 3-3 of Figure l through the casing per se, and shows the specific cross sectional construction of the casing including the mounting of the flexible side walls.
Referring now to the drawing$ in detail, it will be seen that there is illustrated a power module ` .
.i8~
constructed in accordance with this invention and generally identified by the numeral 10. Simply stated, the power module 10 includes a casing 12 and a plurality of cell units 14 disposed within t~e casing 12 in stacked relati~n.
5 E~ch cell unit is prefer~bly formed of a cathode 16 and a consumable anode 18 formed of a material such as lithium and aluminum and the like. There is provided between each cathode 16 and its adjacent an~de 18 an interface 20 which is not part of this invention, but which is such that there can be controlled electrolyte flow along this inter-face between the cathode 16 and the anode 18. The inter-face may be defined either by a grid formation formed on the face of the cathode 16, or by a screen member carried by the face of the cathode. Inasmuch as the constructlon of the cell units per _ is not a part of this invention, the cell units 14 are not described in fur-ther detail here.
At the right end of the casing 10, as shown in Figure 2, there is a terminal plate 22 carrying a terminal 24. At the right end of the stack of cell units 14 there is another terminal plate 26 to which there are connected leads 28 having the opposite ends thereof connected to a second terminal 30.
In addition, within the left end of the casing lo there is provided a cell unit stack pressure applying assembly generally identified by the numeral 32. The assembly 32 is arranged to ~eceive gaseous pressure through a fitting 34 and to apply a constant pressure on the cell unit stack through the terminal plate 26 such that there will be a constant pressure between the anode and cathode of each cell unit along the interface 20 notwithstan~ing the erosion of the anodes in the use of the power module.
This invention most particularly relates to the construction of the casing 12. The casing 12 is of a rectangular confi~uration and is elongated in the direc-tion of stacking of the cell units 14. The cell units 14are disposed vertically within the casing 12.
- :
The casing 12 inclucles a palr of side walls 36 which are suitably connected t:o a bottom wall 38 and a top wall 40. The left end of the casing 12 includes an end wall 42 (Figure 2) and an end wall 44 at the right end of the casing.
Internally of the casing there is a bottom mani-fold plate 46 which is spaced from the bottom wall 38 by suitable spacers 48. A like upper manifold plate 50 is disposed below the top wall 40 and is spaced therefrom by means of suitable spacers 52. As shown in Figure 1, the manifold plates 46, 50 extend the full ]ength of the cas-ing 12 between the end walls 42 and 44. The manifold plates 46, 50 are perforated so that there may be con-stant electrolyte flow through the cell units.
At the right end of the casing 12 there is an upper manifold 54 and a lower manifold 56 (Figure 2). The lower manifold 56 is aligned with the space between the manifold plate 46 and the bottom wall 38 and is in com-munication with that space through suitable openings 58 in the end wall 44. The manifold 56 is preferably a supply manifold.
The upper manifold 54, which is preferably a return manifold, is alignea with the space between the upper manifold plate 50 and the top wall 40 and is in communication with that space by means of suitable open-ings 60 through the end wall 44.
This invention most particularly relates to the provision of the casing 12 with inner deformable walls or plates 62 which are mounted within the casing 12 adja-cent the side walls 36 and extend the full height be-tween the bottom wall 38 and the top wall 40 as is best shown in Figure 3. The side walls 36 have suitable open-ings 64 therethrough through which a suitable gas under pressure may be directed into the space 66 between each set of side walls 36,62.
It is to be noted that the flexible inner side walls 62 engage the side edges of the manifold plates 46, ..
-h~
50 and form seals therewith. Further, since the inner walls 62 extend the ~ull height of the casing, the walls 62 are sealed relative to the top and bottom ~Jalls of the casing.
As shown in Figure 2, the right ends of the walls 62 engage the end wall 44 and form a seal therewith.
The left ends of the walls 62 extend into the area oc-cupied by the assembly 32 which incidentally is shown in the starting stage of the power module in Figure 2 and in the partially consumed stage in Fiqure 1.
As is clearly shown in Figure 2, when the power module 10 is assembled and the spaces between the sets of walls 36, 6Z are pressurized, the flexible walls 62 are forced into contact with the side edges of the anodes and form a seal therewith.
The walls 36, by forming a cell with the verti-cal side edges of the anodes 18 and also with the cathodes 16, prevents the existance of electrolyte alony the sides of the stack of power cells 14. Thus shunt losses along the sides of the cell unit stack are eliminated for all practical purposes.
Further to prevent electrolyte contact with the side edges of the anodes 18, a suitable covering 68 is applied to the vertical side edges of the anodes 18.
This covering is preferably in the form of a tape formed from a rilm of plastics material which is resis~ant to the electrolyte. The covering 68 applied to the vertical side edges of the anodes 1~ directly contacts the inner surfaces of the flexible walls 62 and enhances the forming of the seals between the walls 62 and the anodes 18.
Further, because of the normally slippery nature of plas-tics material films, the friction drag between the anodes and the flexible walls 62 is held to a minimum, thereby permitting the cell units 14 to slide freely within the casing 12 uncler the influence of the assembly 32.
At this time it is pointed out that the casing 12 is preferably formed of suitable plastics material and ' ' . '' . , ~

.. . . . .

.
it has been found that if the flexible walls 62 are to have adequate strength and still be su:Eficiently flexible, they should be formed of plast:ics material having the general characteristics of fiberglass.
Shunt losses at the top and bottom of each cell unit 19 may also be greatly reduced by the use of suitable shunt curtains 70 which ex-tend between adjacent cathodes 16 and are sealed with respect thereto. It is to be under-stood that as the anodes 18 are consumedj the shunt cur-tains 70 will flex so as to pexmit the cathodes 16 to move closer together. The shunt curtains 70 are also formed of a suitable electrolyte resistant material.
It is also to be understood that the covering 68 on each anode 18 may extend along the bottom and top side edges thereof as shown in Figure 1. This covering, in cooperation with the associated shunt curtains, greatly reduces shunt losses at the tops and bottoms oE the anodes.
It is to be understood that the covering material 68 will have sufficient flexibility so that as an anode 18 is consumed, the adjacent covering will fold back and not interfere with the contact of the anodes with the ad]acent cathodes.
The gas utilized to pressurize the spaces 66 may be any suitable gas, although it is preferably the same gas which is customarily used in inerting the power module.
Although only a preferred embodiment of the power module has been specifically illustrated and described herein, it is to be understood that minor variations may be made in the construction of the casing without departing from the spirit and scope of the invention as defined by the appended claims.
