The present invention relates to a method for preparing dihydroxyammonium 5,5'-bistetrazole-1,1′-diolate. The method for preparing dihydroxyammonium 5,5′-bistetrazole-1,1′-diolate, according to one embodiment of the present invention, comprises the steps of: synthesizing 5,5′-bistetrazole-1,1′-diol dihydrate (1,1′-BTO) from ditetrahydropyranyl diazidoglyoxime (THP-DAG) by using a hydrochloric acid (HCl) solution in a first solvent; and reacting 1,1′-BTO with an amine solution so as to neutralize same and, simultaneously, obtaining dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (Thomas Klapotke explosive-50, TKX-50).
