ABSTRACT:
An electrochemical cell system assembled in a closed housing in which said housing has a protruding terminal electronically insulated from and hermetically sealed to said housing using a layer of insulating material (e.g., glass or ceramic) and wherein the exposed external interfacial areas of the insulating material/terminal and the insulating material/cell housing, and preferably also the exposed external area of the insulating material, are coated with a layer of nonconductive, water-resistant, protective material (e.g., wax or asphalt) so as to prevent seal corrosion and electrolyte leakage from the cell when it is exposed to a high humidity environment.
