Abstract

The present invention relates to electrochemical cells including a connector which mates with a connection device to provide electrical connection to meter circuitry.

Claims

1. An electrochemical cell, the electrochemical cell adapted for electrical connection with a meter, the cell comprising a first insulating substrate carrying a first electrically conductive coating, a second insulating substrate carrying a second electrically conductive coating, and an insulating spacer layer disposed therebetween, the electrically conductive coatings being disposed to face each other in a spaced apart relationship, wherein an edge of the first insulating substrate carrying the first electrically conductive coating extends beyond an edge of the second insulating substrate carrying the second electrically conductive coating and beyond an edge of the insulating spacer layer, and wherein the edge of the second insulating substrate carrying the second electrically conductive coating extends beyond the edge of the insulating spacer layer.

2. The electrochemical cell of claim 1, wherein the first insulating substrate carrying the first electrically conductive coating comprises an aperture in a portion of the first insulating substrate carrying the first electrically conductive coating that extends beyond the edge of the insulating spacer, such that an area of the second electrode layer is exposed so as to provide a surface for forming an electrical connection with a meter via the aperture.

3. The electrochemical cell of claim 2, further comprising an additional insulating spacer layer, the additional spacer layer disposed between the first electrically conductive coating and the second electrically conductive coating, wherein the insulating spacer layer and the additional spacer layer are situated on opposite sides of the aperture.

4. An electrochemical cell, the electrochemical cell adapted for electrical connection with a meter, the cell comprising a first insulating substrate carrying a first electrically conductive coating, a second insulating substrate carrying a second electrically conductive coating, and an insulating spacer layer disposed therebetween, the electrically conductive coatings being disposed to face each other in a spaced apart relationship, wherein an edge of the first insulating substrate carrying the first electrically conductive coating extends beyond an edge of the second insulating substrate carrying the second electrically conductive coating and beyond an edge of the insulating spacer layer, and wherein the first insulating substrate carrying the first electrically conductive coating and the insulating spacer layer comprise an aperture, such that an area of the second electrode layer is exposed so as to provide a surface for forming an electrical connection with a meter via the aperture.

5. An electrochemical cell, the electrochemical cell adapted for electrical connection with a meter, the cell comprising a first insulating substrate carrying a first electrically conductive coating, a second insulating substrate carrying a second electrically conductive coating, and an insulating spacer layer disposed therebetween, the electrically conductive coatings being disposed to face each other in a spaced apart relationship, wherein a portion of the first insulating substrate carrying the first electrically conductive coating extends beyond an edge of the second insulating substrate carrying the second electrically conductive coating and beyond an edge of the insulating spacer layer, and wherein a portion of the first insulating substrate carrying the first electrically conductive coating and a portion of the insulating spacer are removed so as to form a notch, the notch situated adjacent to the edge of the second insulating substrate carrying the second electrically conductive coating and the edge of the insulating spacer layer, such that an area of the second electrode layer is exposed so as to provide a surface for forming an electrical connection with a meter.
