An improved seawater electrochemical cell with a consumable anode and an oxygen reducing cathode is provided with a reduced distance between anode and cathode surfaces. The reduced distance does not impede the ingress of oxygen dissolved in water and the egress of reaction products from the cell and causes an increase in the volumetric energy and power density of such dissolved oxygen seawater cells.

Seawater electrolyte electrochemical cell

A metal oxide electrode which uses no additives and only a small amount of a non-film forming binder are capable of discharging at very high current density with near complete utilization of the active material. Oxides of silver and copper are used because the reaction products are more conductive than the conductivity of the reactants.

High rate metal oxide electrodes

A reserve battery cell which includes a battery cell housing, an anode and cathode collector, and a reservoir housing which includes a quantity of electrolyte which, when applied to the anode and cathode collector, cause the battery to generate an electric current through an external load. Burst discs are located proximate the extremities of the reservoir housing. The upstream burst disc is capable of rupturing upon the application of sufficient externally applied pressure while the downstream burst disc is capable of rupturing upon the application of sufficient hydraulic pressure exerted thereon by the electrolyte. The piston is located within the reservoir housing which establishes the upstream boundary of the electrolyte and which is capable of traveling down the reservoir housing upon the application of an externally applied pressure and which is characterized as preventing electrolyte from leaking around the piston and any substantial amount of gas from entering the electrolyte through the piston body.

Moving piston seal activator

A consumable metal anode which is used in refuelable electrochemical cells and wherein at least a peripheral edge portion of the anode is protected against a corrosive alkaline environment of the cell by the application of a thin metal coating, the coating being formed of metals such as nickel, silver, and gold.
