Hence, we have demonstrated a new anode material i.e. sodium iron molybdate [NaFe(MoO4)2] for both LIBs and SIBs. NaFe(MoO4)2 has been successfully synthesized by solid-state combustion technique and tested as a promising new anode material for both LIBs and SIBs. A detailed analysis of the crystal structure has been performed using DFT calculations. NaFe(MoO4)2 crystallizes in the monoclinic phase with the space group C2/c (\#15). FESEM also shows highly crystalline monoclinic shaped crystals of micron size. When evaluated as an anode material for LIBs, NaFe(MoO4)2 electrode exhibited electrochemical capacity of 920 mAhg- 1 in the second cycle at the current density of 50 mAg-1. Though capacity decreases on further cycling, the coulombic efficiency was maintained at 99% for 50 cycles. Significantly, a high discharge capacity of 100 mAhg- 1 was maintained at a very high rate of 1 Ag-1. On the other hand, we have also tested NaFe(MoO4)2 for SIBs which shows excellent reversible specific capacity i.e. 100 mAhg- 1 at the current density of 100 mAg-1 even after 500 cycles. This novel system has shown good stability for LIBs and SIBs which is hitherto unattempted.</p>10aElectrochemical study10alithium-ion battery10aMorphology10aNaFe(MoO4)210aSodium-ion battery1 aTamboli, Asiya, M.1 aTamboli, Mohaseen, S.1 aPraveen, C., S.1 aDwivedi, Pravin, Kumari1 aKarbhal, Indrapal1 aGosavi, Suresh, W.1 a1 aKale, Bharat, B.  uhttp://library.ncl.res.in/content/architecture-nafemoo42-novel-anode-material-rechargeable-lithium-and-sodium-ion-batteries
