Abstract

Abstract : In this paper, a scalable technique, Forcespinning (FS) is employed to produce SnO2 /carbon composite microfibers as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SBIs). The fiber preparation process involved the FS of Tin (II) 2-ethylhexanoate/PAN and PAN solution precursors into fibers and subsequently stabilizing in air at 280 o C and calcined at 800 o C under an inert atmosphere. A hollow and pore microstructure of the SnO2 /CFs were produced that were flexible and were directly used as free-standing anodes in LIBs and SBIs An improved electrochemical performance was observed in the SnO2 /C composite electrode in particular for the sodium ion battery (SIB), with a recorded specific capacity of 198 mAhg -1 after 50 cycles at a current density of 100 mAg -1 . The FS method clearly produced both carbon and SnO2 /C composite fiber electrodes that showed improved electrochemical performance for the SIB due largely to the unique structure and properties of the microfibers.
