A dual-action safety arrangement for a piezoelectric lighter includes an axle holder provided at an inner side of a casing and an ignition cap, which is slidably mounted on a ceiling of the casing in a radially movable manner about an operation axle held at the axle holder, including a depressing arm extended to rest on top of a piezoelectric unit. To ignite the piezoelectric lighter, the ignition cap must be radially and rearwardly slid to actuate a gas emitting nozzle for releasing the gas from a liquefied gas storage and simultaneously depressed to depress a movable operating part of the piezoelectric unit to generate sparks to ignite the gas emitted from the gas emitting nozzle so as to ignite the piezoelectric lighter.

Compositions for hydrogen storage and methods of making such compositions employ an alloy that exhibits reversible formation/deformation of BH anions. The composition includes a ternary alloy including magnesium, boron and a metal and a metal hydride. The ternary alloy and the metal hydride are present in an amount sufficient to render the composition capable of hydrogen storage. The molar ratio of the metal to magnesium and boron in the alloy is such that the alloy exhibits reversible formation/deformation of BH anions. The hydrogen storage composition is prepared by combining magnesium, boron and a metal to prepare a ternary alloy and combining the ternary alloy with a metal hydride to form the hydrogen storage composition.

A method of coating a surface of a fuel cell plate is disclosed herein. The method involves forming a sol gel mixture including a metal oxide modified with at least one functional group, where the at least one functional group is configured to improve adhesion; and adding carbon modified with a hydrophilic functional group to the mixture, thereby forming a suspension. The suspension is applied to the surface of the fuel cell plate, and is activated to form a porous, hydrophilic, and conductive film on the surface of the fuel cell plate.

A foldable polymer-based coil structure and a method for fabricating the same are disclosed. The coil structure has metal wirings and interconnections between the wirings. The wirings and connections are embedded by a polymer. The coil structure is foldable in two or more layers. In the folded condition, coils of one layer overlap the coils of another layer. A stackable structure and jigs for aligning the foldable and stackable structures are also disclosed.

This invention provides a battery, such as a lithium-ion battery, that includes an encapsulated fire-retardant material. In some embodiments, stable polymer spheres are used to encapsulate an effective fire-retardant material. Under normal operating conditions, the fire-retardant material does not contact the electrolyte, cathode, or anode, thus minimizing performance reduction that occurs when fire-retardant materials are in the direct presence of the electrolyte. Under thermal runaway or excessive temperatures, the fire retardant material vaporizes through the melted encapsulating phase, thereby releasing fire-retardant material to minimize or prevent flammability in the battery.

A method of coating a surface of a fuel cell plate is disclosed herein, and involves forming a sol gel mixture by mixing a weak acid and a composition including at least two metal oxide precursors. One of the metal oxide precursors is configured to be hydrolyzed by the weak acid to form a mixed metal oxide framework with an other of the metal oxide precursors having at least one organic functional group that is not hydrolyzed by the weak acid. The mixture is applied to the surface, and is condensed by exposure to air at least one predetermined temperature and for a predetermined time. The sol gel mixture is immersed in water at a predetermined temperature and for a predetermined time to form a porous, hydrophilic, and conductive film on the surface.
