Abstract

Belonging to the technical field of materials, the invention relates to a metal hydride stability treatment method. The treatment method specifically comprises the steps of: (1) dissolving an adhesive in an anhydrous solvent to prepare a liquid glue; (2) adding the liquid glue into a metal hydride, and conducting stirring to form a liquid glue coated metal hydride; and (3) filtering and drying the liquid glue coated metal hydride to obtain the metal hydride undergoing stability treatment. According to the invention, by forming a compact and uniform organic membrane on the metal hydride surface, air and water can be effectively isolated, and the storage time of the metal hydride under normal temperature can be obviously improved, thus solving the storage and use stability problems of the metal hydride under natural conditions.

Description

technical field

[0001] The invention relates to a method for stabilizing metal hydrides, which belongs to the technical field of materials. Background technique

[0002] Hydrogen is the most ideal clean energy carrier in the 21st century, and it has significant advantages such as high gravimetric energy storage density, wide range of sources, recyclability and pollution-free. The application of hydrogen energy involves three technical links: preparation, storage, transportation, and use. At present, solid hydrogen storage has become the most promising hydrogen storage method due to its advantages in hydrogen storage density, operational safety, and cost. Metal hydrides are the earliest and most studied substances in solid hydrogen storage.

[0003] The traditional storage method is to pass the metal hydride through the medium and the device to effectively isolate oxygen and water, such as CeH 2 Preserved in kerosene, and then isolated from air and water with a closed devic...
