A concise electronic timer is composed of an adjustable resistor, a supercapacitor and an electromagnetic relay. After a main power is turned off, electricity supplied from the capacitor to the relay will extend or actuate the operation of a load until the discharge of the capacitor is over. Incorporating the resistor with the other two elements, the discharge time of the capacitor can be altered linearly by the resistor, therefore, a linear arrangement of delay extension and time of activation is attained. The simple, compact and economical timer can be used for indoor and outdoor illumination, monitoring security systems, as well as actuating systems.

Electronic timers using supercapacitors

Iron oxide film directly grown on iron, steel, or other substrates by chemical or electrochemical oxidation is a promising material for energy storage through surface adsorption of static charges. As the electrode materials of energy-storage devices, the hydrated iron compound has a chemical composition of Fe O H , where 1.0&lE;x&lE;3.0, 0.0&lE;y&lE;4.0, and 0.0&lE;z&lE;1.0. An aqueous or organic solution of a metallic salt including sulfates, sulfites, hydroxides, chlorides, phosphates and nitrates is used as electrolyte for the electrochemical devices. Cyclic voltammetry indicates that the iron-oxide electrodes in the electrolytes can store charges as high as 0.5 F/cm or 320 F/g of the electrode materials. Electrochemical capacitors using the iron oxide as the electrode material is an economical and viable power source for use in portable electronics, power tools, and electrical vehicles.

Electrochemical capacitor with electrode material for energy storage

Using thin-films of iron oxide as the active material of electrodes, supercapacitors are fabricated on various substrates in different shapes. By chemical oxidation the iron-oxide film is formed directly and conformably on the substrates in a short period of cooking. The iron oxide has a chemical composition of Fe O H , where 1.0&lE;x&lE;3.0, 0.0&lE;y&lE;4.0, and 0.0&lE;z&lE;1.0. Substrates, as the current collector, tested includes Al, Ti, Fe, Cu and Ni. Measurements by cyclic voltammetry indicates that the iron-oxide electrodes in a selected electrolyte can store charges as high as 0.5 F/cm or 417 F/g of the electrode materials. Supercapacitors as prepared are economical and can be used as enclosure housings for portable electronics, power tools, and batteries. The supercapacitors can also be integrated with the frames and chassis of electric vehicles.

Supercapacitors and method for fabricating the same

A method of manufacturing a cylindrical high voltage supercapacitor. An anode and a cathode are provided. At least one bipolar electrode is interposed between the anode and the cathode, and a separator is intervened in each pair of the above electrodes.
