Abstract
A high energy density hermetic ultraminiature cylindrical cell containing a combination electrolyte fill port and current collector as a hollow metal needle. The cell includes a lithium anode, an electrolyte of an alkali metal salt dissolved in an organic solvent, and a cathode of a chromate, vanadate, molydate, permanganate, iodate, oxide, or carbonmonofluoride.
Claims6
A ultraminiature, electrical cell having a volume of less than about 0.01 cubic inch comprising an elongated, cylindrical metallic container open at one end thereof, a hollow metal needle combination current collector and electrode support, a container sealing means comprising said hollow metal needle having adhered thereto at its upper end means for sealing said open container end, and a layer of a first active solid electrode material adhered to said needle below said sealing means;
- said container having a second active solid electrode material layer on its inner surface;
- said electrode material providing a voltage difference therebetween;
- said needle being closed at its upper end and disposed axially within said container;
- an organic solvent disposed in said container;
- an alkali metal electrolyte salt dissolved in said organic solvent;
- and separating means between said first and second electrode active materials.
