Abstract
A miniature electrochemical cell having a total volume that is less than 0.5 cc is described. The casing enclosure consists of a lower plate supporting a cylindrically-shaped can having an open upper end closed with a cover. The can is selectively coated with a dielectric material to provide electrical isolation of the to-be-housed active materials from the can sidewall. A glass-to-metal seal electrically isolates the lower plate from the can. An electrode assembly comprising a sandwich of cathode active material/separator/anode active material is housed in the casing. That way, the lower plate contacting the cathode active material is the positive terminal and the closing cover connected to the can and contacted to the anode active material serves as the negative cell terminal. An electrolyte filled into the casing activates the electrode assembly and the fill opening is sealed with a plug. The cell can be of either a primary or a secondary chemistry.
