A non-aqueous cell containing a corrosive fluid cathode depolarizer such as thionyl chloride (SOCl.sub.2) and a metal cathode such as of cold rolled steel which is substantially corroded by said fluid depolarizer with the cell having improved high rate discharge characteristics.

Non-aqueous cell with fluid cathode depolarizer and corrodible cathode

An hermetic glass-metal seal, for an electrochemical cell, having a metallic central feedthrough as a terminal thereof which is chemically incompatible with the components of said cell. The feedthrough is connected within said cell to a second compatible metallic element for electrical connection to an electrode within said cell. An inert polymeric material is sealed to the glass or outer metal member of the glass-metal seal and is sealed to and encloses the metallic feedthrough within said cell and the connection area between the feedthrough and said second metallic element.

Hermetic seal for electrochemical cell

A method for cooling high rate discharge primary batteries comprising absorbing the heat of reaction of the primary battery by a nonaqueous liquid depolarizer, circulating it, cooling it, and returning it to the primary battery, and a primary battery system including one or more primary batteries, a cooling means, and a fluid communication means between the primary battery and the cooling means.

High rate discharge primary battery

An internal battery fuse comprising a portion of a current collector which is thermally shielded whereby excessive built-up heat resulting from a short circuit is concentrated in said portion and which heat fuses the shielded portion and interrupts the circuit prior to excessive internal pressure conditions.

Internal battery fuse

An electrochemical cell containing a polyvalent film forming metal anode, a nucleophilic non-aqueous electrolyte solvent and a free radical forming carbon halide additive dissolved in said solvent.

Polyvalent metal anode containing cells

A high energy density cell or battery capable of undergoing flexular stress with little effect on its discharge properties either during and after subjection to stress.

Flexible cells and batteries formed therefrom

A fast chargeable and rechargeable energy storage system to serve as an electrical power supply, that can be fully charged or recharged in less than a minute, consisting of an electric cell with two polar electrodes, as to anode and cathode, with an electrolyte between them, in which the anode and the electrolyte are essentially non-gassing, and the operation during charge is a coupling of a chemical process with an electrochemical process. Circuit voltage is open 0.75 volt and energy storage capacity about 37.5 milliwatt hours in presently available units of small size.

Electrophysichemical device

An electric cell with a plastic seal prone to cold-flow from pressure areas, combined with an elastomeric prone to corrosive action from organic electrolyte, so the plastic will protect the elastomeric, while the elastomeric will compensate for the cold-flow.
