Abstract: A storage battery cell has positive and negative plates flooded by electrolyte. When the battery is charged, gas bubbles are produced in the electrolyte. Baffles are arranged to segregate the hydrogen gas bubbles evolved by a portion of the negative plates from oxygen bubbles formed by the positive plates. A hydrogen gas consuming electrode is submerged in the electrolyte and is located so that a stream of hydrogen bubbles impinges thereon. The gas electrode produces an electric current as a result of the presence of hydrogen and the current is approximately proportional to the quantity of gas impinging on the electrode. When the cell reaches a fully charged state, there is a rapid increase in the rate of gas evolution from the negative plate. This causes a similar increase in the current produced by the electrode. A current sensitive device is used to monitor the current flow and initiate a charge termination sequence when the battery reaches a fully charged state as indicated by the gas electrode. An oxygen consuming electrode may be arranged in a similar fashion to sense the oxygen evolution of the positive plates. A pre-selected rise in current flow from positive gas electrode to negative gas electrode can likewise be used to indicate that both positive and negative plates are fully charged.

Abstract: To a galvanic cell comprising a metallic anode, a depolarizer type cathode and an electrolyte is added a polymerized quaternary ammonium salt having at least two methyl groups and having a molecular weight between about 2,000 and about 100,000. Typical addition agents are: 1. POLY DIMETHYL DIALLYL AMMONIUM CHLORIDE; 2. CO-POLYMERIZED DIMETHYL DIALLYL AMMONIUM CHLORIDE AND ACRYLAMIDE; 3. CO-POLYMERIZED DIMETHYL DIALLYL AMMONIUM CHLORIDE AND DIACETONE ACRYLAMIDE; 4. CO-POLYMERIZED DIMETHYL DIALLYL AMMONIUM CHLORIDE AND METHYL DODECYL-AMMONIUM CHLORIDE; 5.

Abstract: An alkaline battery having a divalent silver oxide (AgO) positive active material (cathode) in which gold ions are incorporated into the alkaline electrolyte on the positive side of the battery separator or barrier or added to the positive active material. The gold additive improves the stability of the divalent silver oxide (AgO) active material in the aqueous alkaline electrolyte without adversely affecting the electrochemical reactions during the discharge of the battery. The additive is present in the battery in amounts ranging from about 0.1 to about 10% by weight of silver in the divalent silver oxide positive active material. It is preferred that the divalent silver oxide active material contain at least 50% by weight of divalent silver oxide (AgO) with the balance of the active material comprising monovalent silver oxide (Ag2O) and metallic silver. The gold additive may be combined with other additives and has been found to be particularly effective in some batteries when combined with mercury and incorporated into either the positive active material or the electrolyte on the positive side of the separator.

Abstract: A galvanic cell and battery sealant is described in which the sealant between container and cover has a permanent foam structure. The sealant may be any of the available sealant materials known to the art, having the properties of adherence, foamability, permanence and inertness to the battery electrolyte. The foamed sealant is equally suitable for batteries closed by sealant alone without a cover. Typical sealant materials are foamed epoxy, foamed phenolic, foamed furan and foamed polyester. The density of the foamed material may be chosen to be between 2 and 50 lbs. per cubic ft. A method for sealing galvanic batteries and cells also form a part of the invention. The foam sealant is readily removeable for battery repair.

Abstract: A comparator element for gaseous oxygen comprises a first and a second oxygen-inert metal electrochemical cell. The first cell is fed with an oxygen containing gas of known oxygen content and the second cell is fed with a gas of unknown oxygen content. The design of the electrochemical cells is such that their electrical resistance when current is passed therethrough is inversely proportional to the oxygen content of the feed gas over a useful range. By comparing the resistances of the two cells, an accurate determination of the oxygen content of the unknown gas may be made with self compensation for ambient temperature. The range of the instrument may be increased by restricting the flow of gas to the oxygen electrodes. This may be accomplished by flowing the gas through a diffusion membrane and an orifice. Oxygen evolved from the metal electrode of the standard cell may be used to feed the oxygen electrode of the same cell thus providing a self sustaining standard atmosphere. The comparator may be compensated for pressure by providing pressure equalizing means between the gas feed to the first cell and the gas feed to the second.
