Abstract
An improved case is provided for a lithium/metal sulfide battery. The improved case is arranged such that the largest surface, corresponding to the side of a traditional cell case, is left open. The remaining five sides of the case can be formed in a drawn form from a single sheet of metal. The electrode plates can be provided within this drawn case and a cover can then be welded to the case to form the cell assembly. Utilizing the side of the cell case rather than the top of the cell case provides easier handling and installation of the electrode plates within the cell case.
Claims2
A lithium metal sulfide battery having a case within which at least one positive electrode and at least one negative electrode are provided, said case having a top, a bottom opposite said top, two ends and two sides, said sides having the largest dimensions in said case, said case comprising:
- a) a first member comprising said top, said bottom, said two ends and one of said two sides, said first member being formed in a drawn form from a sheet of metal;
- and
- b) a cover comprising the other of said two sides, said cover being secured to said first member after said at least one positive electrode and at least one negative electrode are provided within said first member;
- c) a terminal electrically connected to one of said electrodes, the other of said electrodes being electrically connected to said first member;
- d) said top including an aperture therein;
- e) said terminal extending through said aperture in said top and being electrically insulated from said first member.
