Abstract:
Electrical apparatus comprising a combination of a low-power electrical circuit (3), a source of low electrical current comprising at least one cavity (18, 19, 20) for containing liquid electrolyte; a cathode (21) of a first electrically conductive substance having a tendency to act as an oxidizing agent in the presence of a selected second electrically conductive substance and which is positioned within said at least one cavity; an anode (11, 12, 13) of a said selected second electrically conductive substance having a tendency to act as a reducing agent in the presence of said first electrically conductive substance and which is positioned within said at least one cavity; first means for permitting the introduction of a liquid electrolyte into said at least one cavity; and second means for permitting air to be discharged from said at least one cavity when said liquid electrolyte is introduced into said respective cavity; and electrical conductor means connecting said current and said electrical circuit for supplying electrical current to said electrical circuit.
Abstract:
A process for obtaining a porous cathode material composed of Al and Al alloy by using a liquid mixture composed of an acidic solution having a passivating action, a compound capable of accelerating ionization, and water; and a primary battery using the porous Al material as a cathode and carbon as an anode and using the above-mentioned mixture as an electrolytic solution.
Abstract:
A battery includes a first conductive substrate portion having a first face, and a second conductive substrate portion having a second face opposed to the first face. Each of the first and second faces has a perimeter portion and an interior portion inside the perimeter portion. The battery also includes a first electrode material disposed in contact with the interior portion of at least one of the first and second faces, and a jettable electrolyte material disposed in contact with the first electrode material. A second electrode material is disposed in contact with the electrolyte material, and a conductive tab is disposed in contact with the second electrode material. The conductive tab extends outwardly from the interior region beyond the perimeter portion of at least one of the first and second faces.

Abstract:
This invention relates to the formation of standby structural composite electrical energy storage devices, and a method of producing same. The device may be a standby battery or supercapacitor with first and second electrodes which are separated by a separator structure, wherein the device contains an electrolyte retained in a reservoir. The use of at least one valve allows the addition, removal of electrolyte fluids, and venting of any outgassing by products.
Abstract:
A flexible battery includes at least one electrochemical cell for generating an electrical current, including a cathode collector layer, a cathode layer, an anode layer, and an optional anode collector layer, some or all of which are formed of a dried or cured ink. A first substrate includes a pair of opposed side portions. A first electrode contact is provided that is electrically coupled to the cathode collector layer and is disposed along one of the pair of opposed side portions of the first substrate, and a second electrode contact is provided that is electrically coupled to the anode layer and is disposed along the other of the pair of opposed side portions of the first substrate. The cathode collector layer includes a geometry having a height and a width such that the number of squares is approximately 5 or less.
Abstract:
The invention relates to an electrochemical power source. The essence of the invention: an electrochemical power source comprising a housing having a cavity in which an electrolyte in the form of an aqueous alkali metal hydroxide solution is placed, and two electrodes immersed in the electrolyte, characterized in that one of the electrodes is made of a conductive material chemically inert as to the electrolyte and the other electrode is made of a material with the properties of a valve metal. The technical effect is in increased durability of the electrochemical power source.
Abstract:
A non-stick product is described. It comprises a metal substrate (2), such as steel, with a hydrophobic oxide layer (1) having a substantially amorphous microstructure. The non-stick product is preferably produced by means of PVD. A suitable process to be used is electron beam evaporation (EB). It may be used in manufacturing processes for electrical components, such as capa1citors or batteries, or as surfaces in contact with low temperature melting metals.
