Description
Technical Field
The invention relates to the field of hydrogen storage alloy materials, in particular to a method for improving solid-state gold storage performance of a titanium-based zirconium-based alloy by using an activation method.
Background
Hydrogen storage is one of the key links for hydrogen energy utilization, and solid-state hydrogen storage is a safe hydrogen storage mode. Wherein, the metal hydride hydrogen storage has the advantages of low hydrogen storage pressure (less than 5MPa), high hydrogen storage density (more than 50kg/m3) and high hydrogen purity (more than 99.999 percent), and is a safe and efficient hydrogen storage mode. Metal hydride hydrogen storage materials can be classified into rare earth series, titanium series, zirconium series, magnesium series, and the like according to the main types of constituent elements, and only rare earth series are commercially applied on a small scale at present. The zirconium system and the titanium system have large hydrogen absorption amount and low hydrogen release temperature, also have commercial application prospect, especially the titanium system hydrogen storage material has rich raw materials and low price, the TiFe system alloy and the TiMn2 system alloy in the titanium system hydrogen storage material are respectively typical representatives of AB type and AB2 type hydrogen storage alloys, the hydrogen can be absorbed and released reversibly at room temperature by 1.8-2.1 wt%, the decomposition pressure of hydride at room temperature is only a few atmospheric pressures, the cost of the titanium system hydrogen storage alloy is only one third of that of rare earth system, and the advantages are obvious.
Hydrogen storage alloys must be activated prior to hydrogen absorption and desorption because the alloy surface is typically covered with a dense oxide layer that prevents hydrogen atoms from entering the alloy interior. Therefore, before using the hydrogen storage alloy to absorb and release hydrogen, it must be activated at high temperature and high pressure to make hydrogen penetrate the oxide layer on the surface. However, when hydrogen enters the interior of the alloy, the alloy expands causing the particles to burst and form a new surface. The activation means that the hydrogen absorbing alloy reacts with hydrogen atoms for the first time at high temperature and high pressure.
The existing solid hydrogen storage alloy needs to be pretreated at high temperature before absorbing and desorbing hydrogen so as to improve the solid gold storage performance, but the solid hydrogen storage alloy has the problems of high cost and inconvenient operation, still causes the poor hydrogen absorption and desorption performance of the solid hydrogen storage alloy, has low use efficiency and the like, and therefore, aiming at the current situation, the method for improving the solid gold storage performance by using the titanium-based zirconium-based alloy and the activation method is urgently needed to be developed so as to overcome the defects in the current practical application.
