Preparation method of hydrogen storage material

Abstract

The invention belongs to the field of hydrogen storage material production, and particularly relates to a hydrogen storage material preparation method which comprises the following steps: S1, raw materials such as graphite powder are put into a reaction tank, a vacuumizing device is started, and the interior of the reaction tank is vacuumized; s2, after the interior of the reaction tank body is vacuumized, starting a heating device to heat the interior of the reaction tank body; s3, starting a rotating assembly to drive a conveying auger and a stirring rod to rotate, so as to stir the raw materials in the reaction tank body; s4, after the raw materials in the reaction tank completely react to form graphene, taking out a finished product; through the structural design that the rotating assembly drives the conveying auger and the stirring rod to rotate, and then the stirring rod drives the stirring blades to rotate, the function that raw materials in the reaction tank body can be more uniform is achieved, and the problem that the reaction is incomplete when graphite powder is converted into graphene is effectively solved.

Description

technical field

[0001] The invention belongs to the field of production of hydrogen storage materials, in particular to a preparation method of hydrogen storage materials. Background technique

[0002] Hydrogen storage materials refer to materials that can absorb and release hydrogen gas. Early hydrogen storage materials are mostly metals and alloys that can store hydrogen, collectively referred to as hydrogen storage alloys.

[0003] Graphene is an emerging hydrogen storage material, which uses the excellent specific surface area of ​​graphene to store and release hydrogen in the form of molecules through physical adsorption.

[0004] In the prior art, in the process of heating graphite powder and then converting it into graphene, the reaction of graphite powder often occurs incompletely, so that the finished graphene contains impurities, which makes the purity of graphene relatively low. Therefore, the present invention provides a method for preparing a hydrogen storage m...

Embodiment 2

[0047] Such as Figure 9 As shown in Comparative Example 1, as another embodiment of the present invention, a ball 32 is buckled and connected to the side wall of the oblique push block 28; the ball 32 is arranged at a position corresponding to the eccentric wheel 22; When working, when the eccentric wheel 22 contacts the side wall of the oblique push block 28, and then promotes the oblique push block 28 to slide, the ball 32 can reduce the friction between the eccentric wheel 22 and the oblique push block 28, thereby making There is less wear between the eccentric wheel 22 and the balls 32 .

[0048] Working principle: when working, when graphene needs to be prepared, graphite powder can be added to the inside of the reaction tank 1, and then the vacuum device 14 is started, and the internal air of the reaction tank 1 is drawn out through the exhaust pipe 15, so that the reaction A vacuum environment is formed inside the tank body 1, and then the heating device 13 is started...
