~L068333 1 another country. The types of messages which can be so
2 transmitted include not only telephone conversations but also such things as data communications and television 4 pictures.
In constructing such a communication satellite, it 6 is important to make the components thereof as light in weight 7 as possible.

SUMMARY OF THE INVENTION
This invention relates to a battery structure and, 26 more particularly, to a lightweight battery structure which 27 is suitable for use in spacecraft applications.
1061~333 1 In accordance with the general teachings of this 2 invention, the lightweight battery structure comprises a
3 plurality of cells. Each cell has a plurality of non-
4 strengthened cell walls. Such nonstrengthened cell walls contact other nonstrengthened cell walls of other cells when 6 the celis are in an assembled condition. Each cell also has 7 at least one strengthened cell wall. This strengthened cell 8 wall does not contact any other cell wall of any other cell g when the cells are in an assembled condition. A pair of structurally strengthened end plates are located at opposite 11 ends of the cells when the cells are in an assembled condi-12 tion. These end plates provide support for any nonstrengthened 13 cell walls of the cells coming in contact therewith. Holding 14 structure is provided for holding the cells and the struc-turally strengthened end plates in an assembled condition.
16 In such an assembled condition, the nonstrengthened cell 17 walls are supported by one another or by the structurally 18 strengthened end plates whereas the strengthened cell walls 19 Of the cells are exposed and not supported by any contacting cell walls of other cells.
21 In accordance with the preferred teachings of this 22 invention, the nonstrengthened cell walls may be made from 23 a thin metal sheet. In this case, the strengthened cell walls 24 are made from the same thin metal sheet which has die form channels located therein in order to lend rigidity and greater 26 strength to the walls.
27 Another form of the invention is embodied in a 28 structure in which the nonstrengthened cell walls are formed 29 from a very thin fiber reinforced composite material of 1~)68333 1 lightweight. In this case, the strengthened walls are formed 2 from a reinforced honeycomb structure which has substantially 3 greater strength than do the nonstrengthened walls.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
14 In order to illustrate the principals of this inven-tion, two preferred embodiments of the invention are disclosed 16 herein. The first embodiment is disclosed in FIGURES 1 through 17 4 in which individual cells of the overall battery are made 18 from metal walls. In the second embodiment disclosed in lg FIGURES 5 through 7, the cell walls are made from a mixture of metal and fiber reinforced composite structures. These two 21 different embodiments will be discussed in detail hereinbelow.
22 In FIGURE 1, there is seen a battery generally 23 designated by the numeral 10. The battery includes a plurality 24 of cells 12 which in the embodiment shown are formed so that four cells make up one cross section of the battery. In the ~106~3333 1 battery shown there are eighteen rows of the four-cell units.
2 In total, therefore, the battery 10 contains 72 individual 3 cells.
4 The construction for the individual cells is best seen by referring to FIGURES 2 and 3. In this embodiment the 6 individual cells 12 are formed from a plurality of cell walls.
7 With reference to FIGURE 2, a back cell wall 14 and a bottom 8 cell wall 16 of an individual cell 12 are formed from a 304L
9 stainless steel or nickel alloy such as 718A Inconel (trade-mark) sold by International Nickel Company which has a thick-11 ness in the range from .004 inch to .010 inch. Side walls 18 12 (shown best in FIGURE 3) of each cell are formed of the same 13 material. The walls 14, 16 and 18 are nonstrengthened walls.
14 It is readily apparent, however, that these nonstrengthened walls abut similar nonstrengthened walls of other cells either 16 in the same row therewith or in adjacent rcws whereby support 17 is obtained for the nonsupported walls. The support obtained 18 is a mutually dependent support with one nonsupported wall 19 supporting that in contact with it in a mutual relationship.
Once again with reference to FIGURE 2, an upper wall 21 20 and an outer side wall 22 of each of the cells 12 has a 22 plurality of die formed strengthening channels 24 therein for 23 the purpose of strengthening these outer walls. These outer 24 walls are also formed of the same material as the previously described walls. These die formed channels have a radius of 26 75 to 120 mils and are formed by metal sheet drawing process.
27 These die formed channels strengthened the outer wall to pre-28 vent bending and deflection damage to the container due to 29 internal cell pressure increases normally encountered during 1 overcharge operation. When the individual cells 12 are in an 2 assembled condition, the strengthened walls are not in contact 3 with cell walls of other cells.
4 A pair of structurally strengthened end plates generally identified by the numeral 26 are located at opposite 6 ends of the assembled cells 12 as is best seen in FIGURE 1.
7 These end plates have a pair of projecting portions 28 through ; 8 which a through bolt 30 extends to receive suitable nuts 32 9 thereon. By such means, the end plates hold the plurality of cells 12 in an assembled condition.
11 Each end plate 26 is formed from a llghtweight alumi-12 num structure in which the faces o~ the members are made from 13 thin aluminum. The internal portion of each end plate is 14 formed from an aluminum honeycomb 34, shown only in FIGURE 1, in which the cell spacing is approximately 1/4 inch. Each 16 end plate also provides structural support for the non-17 strengthened side cell walls which come in contact therewith.
18 In accordance with the construction of this inven-19 tion, individual cells 12 have both nonstrengthened cell walls and strengthened cell walls. In the final assembly, the non-21 strengthened cell walls contact either other nonstrengthened 22 cell walls to provide support therefor or contact the struc-23 turally strengthened end plates to provide support therefor.
24 The structurally strengthened cell walls do not engage any other cell wall and are generally exposed. By providing 26 strengthened walls for only those walls which arenonsupported, 27 the cost of making the battery cell is reduced because it is 28 not necessary to carry out the die forming strengthening opera-29 tion on the nonsupported walls. Also, the walls can be rela-- `~
~L06~333 1 tively thin because those which are not supported ky other 2 walls are the only walls which are strengthened.
3 Reference is now made to the battery generally 4 identified by the numeral 110 as shown in FIGURE 5. Once again in this construction, a plurality of battery cells 6 generally identified by the numeral 112 are provided. These 7 cells are stacked in a manner similar to the stacking of the 8 cells 12 previously described with the battery 10. In this 9 situation, however, the structure is built slightly different.
Reference is made to-FIGURE 6 wherein a back wall 114 and a 11 bottom wall 116 are shown. These walls are nonstrengthened 12 walls and they are made from a fiber reinforced epoxy com-13 posite such as manufactured by Fiberite Corporation of 14 Winoma, Minnesota which has a thickness of ~004 inches. This material is identified by Fiberite as their material HYE 1334.
16 The material could also be an epoxy fiber such as manufactured 17 by DuPont under the name Kevlar (trademark) whlch has a thick-18 ness of 0.004 inches. Another material which is suitable is a 19 fiberglass epoxy manufactured by Hexcell having a thickness of 0~004 inches and identified by Hexcell as their number 21 F161-120. As shown in FIGURE 7, the side walls 118 of each 22 cell 112 can also be made of this same relatively thin material.
23 An upper wall 120 and an outer side wall 122 are 24 made by forming a sandwich of ~wo thir. sheets of materials such as identified above between a honeycomb matrix formed 26 of this material. Such material may be konded together with 27 an epoxy adhesive such as manufactured by American Cynamid 28 and identified by their number FM123. This laminated sand-29 wich provides structural strength in those walls which are not supported ky other adjacent walls.
r ~
106~333 1 The plurality of individual cells 112 are supported 2 by the use of structurally strengthened end plates 26, 26 as 3 was described before during the description of the battery 10.
4 These structurally strengthened end plates 26 are formed in the same manner as described previously and function in a 6 manner whereby they hold the plurality of cells in an assembled 7 condition. In their assembled conditions, the structurally 8 strengthened walls of the cells are exposed and not engaged 9- by other cell walls whereas the nonstrengthened walls engage other nonstrengthened walls to find support therefor or engage 11 the strengthened end plates to provide strength therefor.
12 There has been disclosed herein a battery structure 13 which is of lightweight construction. In view of the teach-14 ings of this specification, those skilled in the art will be able to make other modifications thereof which fall 16 within the true spirit and scope of this invention. It is 17 intended that all such modifications be included within the 18 scope of the appended claims.
19 ~
16 In such an assembled condition, the nonstrengthened cell 17 walls are supported by one another or by the structurally 18 strengthened end plates whereas the strengthened cell walls 19 Of the cells are exposed and not supported by any contacting cell walls of other cells.
21 In accordance with the preferred teachings of this 22 invention, the nonstrengthened cell walls may be made from 23 a thin metal sheet. In this case, the strengthened cell walls 24 are made from the same thin metal sheet which has die form channels located therein in order to lend rigidity and greater 26 strength to the walls.
27 Another form of the invention is embodied in a 28 structure in which the nonstrengthened cell walls are formed 29 from a very thin fiber reinforced composite material of 1~)68333 1 lightweight. In this case, the strengthened walls are formed 2 from a reinforced honeycomb structure which has substantially 3 greater strength than do the nonstrengthened walls.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
14 In order to illustrate the principals of this inven-tion, two preferred embodiments of the invention are disclosed 16 herein. The first embodiment is disclosed in FIGURES 1 through 17 4 in which individual cells of the overall battery are made 18 from metal walls. In the second embodiment disclosed in lg FIGURES 5 through 7, the cell walls are made from a mixture of metal and fiber reinforced composite structures. These two 21 different embodiments will be discussed in detail hereinbelow.
22 In FIGURE 1, there is seen a battery generally 23 designated by the numeral 10. The battery includes a plurality 24 of cells 12 which in the embodiment shown are formed so that four cells make up one cross section of the battery. In the ~106~3333 1 battery shown there are eighteen rows of the four-cell units.
2 In total, therefore, the battery 10 contains 72 individual 3 cells.
4 The construction for the individual cells is best seen by referring to FIGURES 2 and 3. In this embodiment the 6 individual cells 12 are formed from a plurality of cell walls.
7 With reference to FIGURE 2, a back cell wall 14 and a bottom 8 cell wall 16 of an individual cell 12 are formed from a 304L
9 stainless steel or nickel alloy such as 718A Inconel (trade-mark) sold by International Nickel Company which has a thick-11 ness in the range from .004 inch to .010 inch. Side walls 18 12 (shown best in FIGURE 3) of each cell are formed of the same 13 material. The walls 14, 16 and 18 are nonstrengthened walls.
14 It is readily apparent, however, that these nonstrengthened walls abut similar nonstrengthened walls of other cells either 16 in the same row therewith or in adjacent rcws whereby support 17 is obtained for the nonsupported walls. The support obtained 18 is a mutually dependent support with one nonsupported wall 19 supporting that in contact with it in a mutual relationship.
Once again with reference to FIGURE 2, an upper wall 21 20 and an outer side wall 22 of each of the cells 12 has a 22 plurality of die formed strengthening channels 24 therein for 23 the purpose of strengthening these outer walls. These outer 24 walls are also formed of the same material as the previously described walls. These die formed channels have a radius of 26 75 to 120 mils and are formed by metal sheet drawing process.
27 These die formed channels strengthened the outer wall to pre-28 vent bending and deflection damage to the container due to 29 internal cell pressure increases normally encountered during 1 overcharge operation. When the individual cells 12 are in an 2 assembled condition, the strengthened walls are not in contact 3 with cell walls of other cells.
4 A pair of structurally strengthened end plates generally identified by the numeral 26 are located at opposite 6 ends of the assembled cells 12 as is best seen in FIGURE 1.
7 These end plates have a pair of projecting portions 28 through ; 8 which a through bolt 30 extends to receive suitable nuts 32 9 thereon. By such means, the end plates hold the plurality of cells 12 in an assembled condition.
11 Each end plate 26 is formed from a llghtweight alumi-12 num structure in which the faces o~ the members are made from 13 thin aluminum. The internal portion of each end plate is 14 formed from an aluminum honeycomb 34, shown only in FIGURE 1, in which the cell spacing is approximately 1/4 inch. Each 16 end plate also provides structural support for the non-17 strengthened side cell walls which come in contact therewith.
18 In accordance with the construction of this inven-19 tion, individual cells 12 have both nonstrengthened cell walls and strengthened cell walls. In the final assembly, the non-21 strengthened cell walls contact either other nonstrengthened 22 cell walls to provide support therefor or contact the struc-23 turally strengthened end plates to provide support therefor.
24 The structurally strengthened cell walls do not engage any other cell wall and are generally exposed. By providing 26 strengthened walls for only those walls which arenonsupported, 27 the cost of making the battery cell is reduced because it is 28 not necessary to carry out the die forming strengthening opera-29 tion on the nonsupported walls. Also, the walls can be rela-- `~
~L06~333 1 tively thin because those which are not supported ky other 2 walls are the only walls which are strengthened.
3 Reference is now made to the battery generally 4 identified by the numeral 110 as shown in FIGURE 5. Once again in this construction, a plurality of battery cells 6 generally identified by the numeral 112 are provided. These 7 cells are stacked in a manner similar to the stacking of the 8 cells 12 previously described with the battery 10. In this 9 situation, however, the structure is built slightly different.
Reference is made to-FIGURE 6 wherein a back wall 114 and a 11 bottom wall 116 are shown. These walls are nonstrengthened 12 walls and they are made from a fiber reinforced epoxy com-13 posite such as manufactured by Fiberite Corporation of 14 Winoma, Minnesota which has a thickness of ~004 inches. This material is identified by Fiberite as their material HYE 1334.
16 The material could also be an epoxy fiber such as manufactured 17 by DuPont under the name Kevlar (trademark) whlch has a thick-18 ness of 0.004 inches. Another material which is suitable is a 19 fiberglass epoxy manufactured by Hexcell having a thickness of 0~004 inches and identified by Hexcell as their number 21 F161-120. As shown in FIGURE 7, the side walls 118 of each 22 cell 112 can also be made of this same relatively thin material.
23 An upper wall 120 and an outer side wall 122 are 24 made by forming a sandwich of ~wo thir. sheets of materials such as identified above between a honeycomb matrix formed 26 of this material. Such material may be konded together with 27 an epoxy adhesive such as manufactured by American Cynamid 28 and identified by their number FM123. This laminated sand-29 wich provides structural strength in those walls which are not supported ky other adjacent walls.
r ~
106~333 1 The plurality of individual cells 112 are supported 2 by the use of structurally strengthened end plates 26, 26 as 3 was described before during the description of the battery 10.
4 These structurally strengthened end plates 26 are formed in the same manner as described previously and function in a 6 manner whereby they hold the plurality of cells in an assembled 7 condition. In their assembled conditions, the structurally 8 strengthened walls of the cells are exposed and not engaged 9- by other cell walls whereas the nonstrengthened walls engage other nonstrengthened walls to find support therefor or engage 11 the strengthened end plates to provide strength therefor.
12 There has been disclosed herein a battery structure 13 which is of lightweight construction. In view of the teach-14 ings of this specification, those skilled in the art will be able to make other modifications thereof which fall 16 within the true spirit and scope of this invention. It is 17 intended that all such modifications be included within the 18 scope of the appended claims.
