The invention relates to a compound of the formula LiPSX(BH), in which x is selected from the group comprising Cl, Br, I, F and CN, 0&#x2264;x&#x2264;2, 0&#x2264;z&#x2264;0.50. This compound can be used as a solid electrolyte of a lithium-ion electrochemical element.

Solid electrolyte for a lithium-ion electrochemical cell

Systems and methods for manufacturing a tank for storing hydrogen in metal hydride powder are disclosed. The tank can include a closed enclosure divided into closed cells. Each of the cells can contain metal hydride powder. Each of the cells can also be manufactured successively by assembling the cells in order to form an open cavity or alveolar cell. One or more bulk pieces of a material capable of forming a metal hydride can be placed in the cavity. The cell can be closed with the bulk pieces by closing the cavity. After cells are closed, hydrogen can be introduced into the tank for transforming the bulk pieces into metal hydride powder.

A device for trapping flammable gases such as hydrogen comprises active means () inside a casing () which is closed except for openings which are plugged by filters () that normally allow only the gases that are to be trapped to pass through them. The trapping maintains a reduced pressure inside the casing, which continually draws in the gases produced outside. The trap can operate without any maintenance and for long periods of time, even in a completely enclosed environment.
