AB  - Herein, we report additive- and binder-free pristine amorphous vanadium oxide 
      (a-VOx) for Li- and Na-ion battery application. Thin films of a-VOx with a 
      thickness of about 650 nm are grown onto stainless steel substrate from 
      crystalline V(2)O(5) target using pulsed laser deposition (PLD) technique. Under 
      varying oxygen partial pressure (pO(2)) environment of 0, 6, 13 and 30 Pa, films 
      bear O/V atomic ratios 0.76, 2.13, 2.25 and 2.0, respectively. The films 
      deposited at 6‑30 Pa have a more atomic percentage of V(5+) than that of V(4+) 
      with a tendency of later state increased as pO(2) rises. Amorphous VOx films 
      obtained at moderate pO(2) levels are found superior to other counterparts for 
      cathode application in Li- and Na-ion batteries with reversible capacities as 
      high as 300 and 164 mAh g(-1) at 0.1 C current rate, respectively. At the end of 
      the 100th cycle, 90% capacity retention is noticed in both cases. The observed 
      cycling trend suggests that more is the (V(5+)) stoichiometric nature of a-VOx 
      better is the electrochemistry.
