The present invention relates to an amorphous anode active material, a preparation method of an electrode using the same, a secondary battery containing the same, and a hybrid capacitor, wherein the amorphous anode active material according to the present invention comprises at least one of a metal oxide or a metal phosphate, and the metal oxide or the metal phosphate is amorphous. The metal oxide has the form of MOX (0 < X ≤ 3), wherein M is at least one of molybdenum (Mo), vanadium (V), scandium (Sc), titanium (Ti), chromium (Cr), yttrium (Y), zirconium (Zr), niobium (Nb) and tungsten (W). The metal phosphate has the form of AxBy(PO4) (0 ≤ x ≤ 2, 0 < y ≤ 2), wherein A is at least one of lithium (Li), sodium (Na) and potassium (K), and B is at least one of molybdenum (Mo), vanadium (V), scandium (Sc), titanium (Ti), chromium (Cr), yttrium (Y), zirconium (Zr), niobium (Nb) and tungsten (W). According to the present invention, the storage space of lithium, sodium, and the like and the diffusion ...
