Abstract in another language

Nanocrystalline SnF2 was prepared via recrystallization of commercially available tin (II) fluoride. The electrochemical performance of tin fluoride as anode material for Li-ion batteries was investigated. The cyclic voltammetry of the obtained material showed occurrence of SnF2 decomposition at first and a typical reversible alloying/de-alloying process at low potentials. Furthermore, it was found that the synthesized material delivered a high reversible capacity of 1016 mAhg- 1 and a capacity retention of 54.8% after 30 cycles when the electrode was cycled at a current of 100 mA g- 1.
