1. An in-situ preparation method of nano magnesium hydride, comprising steps of:
step (1) disposing and stirring magnesium dichloride and lithium hydride in a first organic solvent under a protection of an inert atmosphere, so as to obtain an organic suspension of a mixture;
step (2) performing an ultrasonic treatment to the organic suspension under the protection of the inert atmosphere, so as to promote a chemical reaction of the mixture, after the chemical reaction is completed, the organic suspension is filtered to obtain a solid reaction product; and
step (3) washing, centrifuging and drying the solid reaction product by using a second organic solvent under the protection of the inert atmosphere, so as to remove a residual organic material and obtain nano-magnesium hydride.
