A film coating for use in combination with an in-vivo signal generating reference electrode coupled to a condition responsive means and adapted to sense a condition of a body fluid within the host, wherein the film coating comprises a silicone based polymer having adhesive and cohesive properties performing an adherent and coherent film coating upon the signal generating reference electrode, and wherein the film contains potassium chloride therewithin in a concentration range between 20 and 40 milligrams per gram of polymer solids. The cross sectional thickness of the cured film is sufficiently large so as to stabilize and improve the mechanical properties of the electrode components, but sufficiently limited so as to reduce any adverse effect upon cell response.

Coating for silver/silver chloride reference electrode

A novel inorganic non-aqueous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an SO.sub.2 solvent with an alkali or alkaline earth metal halide salt of aluminum, tantalum niobium or antimony, dissolved in the SO.sub.2 and a cathode comprised of a carbonaceous material having an apparent bulk density in excess of 5 lb/ft.sup.3 (80 gm/l). Lower bulk density carbonaceous material may, however, be used in electrolytes having high salt concentrations. Ketjenblack EC (furnace black) carbonaceous material may be admixed with a solid cathode active material which is substantially insoluble in the SO.sub.2 electrolyte to provide a high primary cell capacity and an effectively rechargeable cell. There is no SO.sub.2 per se discharge in the cell.

Inorganic non-aqueous cell

A non-aqueous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an electrolyte salt and sulfur dioxide and a cathode comprised of PbCl.sub.2.

Cell with PbCl.sub.2 cathode

A non-aqueous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an electrolyte salt and sulfur dioxide and a cathode comprised of CoCl.sub.2.

Cell with CoCl.sub.2 cathode

A non-aqeous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an electrolyte salt and sulfur dioxide and a cathode comprised of FeBr.sub.3.

Cell with FeBr.sub.3 cathode

A non-aqueous electrochemical cell having an alkali or alkaline earth metal anode, an inorganic electrolyte comprised of an electrolyte salt and sulfur dioxide and a cathode comprised of NiCl.sub.2.
