Abstract: A dry cell construction having a one-piece plastic closure covering the open end of the negative electrode can which contains a depolarizer mix and a current collector centrally imbedded in the depolarizer mix. The plastic closure rests on the top edge of the negative electrode can and has a tubular projection extending from the bottom thereof through which the current collector passes. The tubular projection covers the current collector throughout an airspace located above the depolarizer mix. The plastic closure contains at least one venthole extending from its top surface into contact with the airspace above the depolarizer mix and at least one groove in the top surface of the closure extending from the outer edge of the closure into contact with the airspace between the terminal cap on top of the current collector and the plastic closure. It is preferred that the plastic closure have a plurality of ventholes and grooves which are offset from each other. The cell construction of this invention is particularly adapted for rechargeable dry cells which utilize a depolarizer mix containing an azodicarbonamide depolarizer material.

Abstract: A method of extruding an electrode along the inner surfaces of a cylindrical cell container and a cell having such an electrode. A quantity of an electrode active material is placed in the bottom of the container and a rapidly spinning, cruciform-shaped tool is lowered into the container and extrudes the active material along the container walls. The particular application of the method involves forming a gridless lead electrode in the cell container whereby the cell walls support the active material. A modified tool is used for a rectangular cell container wherein the tool is rectangular, having two surfaces recessed from the tool edges so as to form an open space between the container walls and the recessed surfaces. The tool is continually vibrated and when it is lowered into the container, paste is extruded up the open space and is spread along the inner walls of the container while the tool is vibrating.

Abstract: A METHOD FOR PREPARING AN AIR BREATHING ELECTRODE WHICH COMPRISES APPLYING A CATALYST COMPOSITION TO A METALLIC GRID MEMBER, APPLYING A FLUOROCARBON POLYMER SHEET MATERIAL CONTAINING A POREFORMING AGENT ONTO THE SIDE OF THE CATALYST COMPOSITION AND THEREAFTER REMOVING THE PORE-FORMER FROM THE FLUOROCARBON POLYMER SHEET MATERIAL TO RENDER IT MICROPOROUS. THE FLUOROCARBON POLYMER SHEET MATERIAL IS APPLIED TO THE CATALYST COMPOSITION BY HOT PRESSING TO FIRMLY ATTACH IT THERETO. THE METALLIC SALT CORE-FORMER IS REMOVED FROM THE FLUOROCARBON POLYMER SHEET MATERIAL AFTER IT IS APPLIED TO THE CATALYST COMPOSITION, AND THE PORE-FORMER MAY BE REMOVED BY CONTACTING THE ELECTRODE WITH A LEACHING SOLVENT. AN ALTERNATIVE PROCEDURE COMPRISES APPLYING A LAYER OF A CATALYST COMPOSITION ONTO A FLUOROCARBON POLYMER SHEET MATERIAL CONTAINING A PORE FORMER, PLACING A METALLIC GRID ONTO THE CATALYST LAYER, HOT PRESSING THE GRID/CATALYST/FLUOROCARBON POLYMER TO FORM A UNITARY STRUCTURE, AND THEN REMOVING THE POREFORMER.

Abstract: AN ELECTRIC BATTERY HAVING A LAMINATED SEMIPERMEABLE BARRIER/ABSORBENT SEPARATOR TO PROVIDE IMPROVED CYCLE LIFE AND/OR IMPROVED HIGH TEMPERATURE AND LONG DURATION STORAGE CAPABILITY. THE BATTERY EMPLOYS A CATHODE MATERIAL WHICH IS APPRECIABLY SOLUBLE IN THE ELECTROLYTE, AND THE SEPARATOR IS POSITIONED IN SUCH A MANNER THAT THE SEMIPERMEABLE BARRIER (E.G. CELLOPHANE) IS IN CONTACT WITH THE CATHODE MATERIAL AND THE ABSORBENT MATERIAL IS IN CONTACT WITH THE ANODE. THE ABSORBENT MATERIAL IS SPECIALLY PREPARED FROM A VINYL ACETATE-ETHYLENE COPOLYMER BINDER MATERIAL BLENDED WITH A GELLING AGENT (E.G. STARCH AND FLOUR). THE BARRIER MATERIAL PREVENTS CATHODE ACTIVE MATERIAL FROM MIGRATING TO THE ANODE, AND THE ABSORBENT MATERIAL ABSORBS THE BATTERY ELECTROLYTE AND IMMOBILIZES IT IN CONTACT WITH THE ANODE SURFACE.

Abstract: AN ELECTRIC BATTERY HAVING AN AZODICARBONAMIDE COMPOUND AS THE DEPOLARIZER IN WHICH BORIC ACID IS ADDED TO THE CATHODE (DEPOLARIZER) MIX TO IMPROVE THE EFFICIENCY OF THE AZODICARBONAMIDE COMPOUNDS AS A DEPOLARIZER, TO IMPROVE THE STABILITY OF THE AZODICARBONAMIDE COMPOUNDS, AND TO IMPROVE BATTERY CYCLE LIFE. THE BORIC ACID MAY BE DRY BLENDED WITH THE CATHODE MIX AND /OR DISSOLVED (IT HAS LIMITED SOLUBILITY) IN THE ELECTROLYTE WHICH IS ADDED TO THE CATHODE MIX. THE BORIC ACID MAY BE ADDED TO THE CATHODE MIX IN AMOUNTS RANGING FROM ABOUT 1 TO ABOUT 20% BY WEIGHT OF DRY CATHODE MIX AND /OR DISSOLVED IN THE ELECTROLYTE IN AMOUNTS UP TO SATURATION (ABOUT 6% BY WEIGHT). THE BORIC ACID IS EFFECTIVE FOR BOTH SUBSTITUTED AND UNSUBSTITUTED AZODICARBONAMIDE COMPOUNDS WHEN THEY ARE USED AS BATTERY DEPOLARIZERS.
