Patent ID: 6946067

Claim:
A method for forming an electrical connection between an electrochemical cell and a meter, the method comprising the steps of: a) providing an electrochemical cell, the electrochemical 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; b) providing a meter, the meter comprising a wedge, the wedge comprising an upper wedge conductive surface and a lower wedge conductive surface, the conductive surfaces in electrical communication with the meter; and c) inserting a portion of the electrochemical cell into the meter, whereby the wedge is inserted between the portion of the first insulating substrate carrying the first electrically conductive coating and the portion of the second insulating substrate carrying the second electrically conductive coating that extends beyond the edge of the insulating spacer layer, whereby an electrical connection between the first electrically conductive coating and the lower wedge conductive surface is formed, and whereby an electrical connection between the second electrically conductive coating and the upper wedge conductive surface is formed.
