In this paper, we report a new sodium ion battery formed by coupling a NaFePO4 cathode and a nanocomposite tin-carbon (Sn-C) sodium alloying anode. The NaFePO4 cathode is obtained by Li-Na conversion of a LiFePO4 cathode directly in the full cell employing the Sn-C anode and a sodium-ion electrolyte. The results evidence that the unique approach here adopted is capable to successfully and efficiently convert LiFePO4 into NaFePO4 in a sodium-ion battery operating at a voltage of 3V with maximum reversible capacity of 150 mAh g-1 with high reversibility and rate capability.

Abstract
In this paper, we report a new sodium ion battery formed by coupling a NaFePO4 cathode and a nanocomposite tin-carbon (Sn-C) sodium alloying anode. The NaFePO4 cathode is obtained by Li-Na conversion of a LiFePO4 cathode directly in the full cell employing the Sn-C anode and a sodium-ion electrolyte. The results evidence that the unique approach here adopted is capable to successfully and efficiently convert LiFePO4 into NaFePO4 in a sodium-ion battery operating at a voltage of 3V with maximum reversible capacity of 150 mAh g-1 with high reversibility and rate capability.File in questo prodotto:
