Abstract of the Disclosure Use of Titanium and Titanium alloys in combination with and CABAL-12 glass for improved corrosion resistant feedthroughs.
Description
3 ~i 1 Backaround of the Invention 2 Glass seals are used ln various arrangements 3 including batteries and other electrochemical cells. For 4 exa~ple, in battery headers, glass seals are used to seal the battery container while allowing one or more 6 electrical terminals to extend through the seal for 7 interior/exterior connection thereto. The term 8 "feedthrough" shall be used herein to describe ~such 9 arrangements in generic fashion.
In batteries and the electrochemical cells, 11 corrosion has been encountered. For example, batteries 12 which include various organic electrolyte systems give 13 rise to corrosion and crac~ing of glass and metal 14 feedthrough components.
: A special glass composition has developed by 16 Sandia National Laboratories which exhibit improved 17 corrosion resistance. It is generally referred to as 18 CABAL-12 glass. Although this glass has desirable 19 corrosion resistance and resistance to cracking, it has been difEicult to find metals which will reliably wet the 21 glass to Eorm strong, hermetic seals with it and which 22 work well with respect to the other aspects of seal 23 forming such as weldability, expansion characteristics 24 and so forth. The general purpose of this invention is to provide a combination of metal and CABAL-12 GLASS for 26 improved feedthrough structures ill bal:tery alld 27 electrochemica:L cell applications.
1-- . , ., 2(~L3L2~3 1 summary of the Invention 2 This invention relates to feedthrough 3 structures which utilize CABAL-12 glass particularly for 4 use in aggressive battery organic electrolyte environments e.g., a lithium thionyl chloride cell or 6 cells of other active chemistries such as MnO2, and CFX, 7 for example. It hzs been discovered that this glass has 8 a uni~ue af~inity for sealing to titanium and titanium 9 alloys. In its preferred embodiment the invention relates specifically to hermetic, corrosion resistant, 11 compression-type sealed feedthroughs utilizing single or 12 multiple terminals or pins of niobium, tantalum, 13 molybdenum and titanium or alloy thereof, contained 14 within a header or sleeve of titanium or a titanium alloy, Titanium-6A1-4V being preferred.
16 Brie~ Descrlption of the ~rawinq 17 Fig. l is a schematic cross-section of a 18 battery header in accordance with the invention, and 19 Fig. 2 is a schematic cross-section of a feedthrough with sleeve according to the invention 21 combined with a metal container for use as an 22 electrochemical cell.
23 Description of the Preferred Embodiments 24 While this invention may be embodied in many different forms, there are shown in the drawings and 26 described in detail herein speciPic preferred embodiments 27 of the invention. The present disclosure is an 28 exemplification of the principles of the invention and i5 29 not intended to limit the invention to the particular embodiments illustrated.
31 Referring to Fig. 1, a header of typical 32 construction is shown which includes a center pin or 33 terminal lO, a glass seal member 12 and an outer member 34 14. This arrangement and that of Fig. 2 are typical feedthrough seal arrangements wh.ich may make use of the 2J~
1 invention. Other arrangements may be used as well and 2 may take any configuration in which the metal is wetted 3 by the glass.
4 Referring now to the Fig. 2 the invention in a preferred form includes a terminal 10 extending through 6 a glass seal 12 which is received into a sleeve or header 7 14~ Sleeve 14 may be welded into an opening in a battery 8 container 16 of, for example, stainless steel.
9 The assembly, requiring forming weights, is placed in an oven or furnace and heated causing the glass 11 to wet the metallic components forming a hermetic seal 12 between the glass and the metal components. Such a 13 feedthrough may thereafter be welded if necessary, into 14 any desirable container or the like.
In its preferred form, terminal 10 consists 16 essentially of niobium, or titanium or an alloy thereof.
17 Sleeve 14 is of titanium or a titanium alloy Ti-6A1-4V
18 The glass 12 is CABAL-12, which is of the following 19 composition:
Composition Wt. M~
23 CaO 20 24 MgO 20 26 'rhe combination of materials des~ribed forms a 27 compression seal which ls hermetic and corrosion 23 resistant.
29 This completes the description of the preferred and alternate embodiments of the invention. Those 31 skilled in the art may recognize other equivalents to the 32 specific embodiments described herein, which equivalents 33 are intended to be encompassed by the claims attached 34 hereto.
1 Having described the invention, the exclusive 2 rights and privileges thereto are to be defined by the 3 foregoing claims in the light of the foregoing 4 description.
