Data on effect of electrospinning conditions on morphology and effect of heat-treatment temperature on the cycle and rate properties of core-shell LiFePO/FeS/C composite fibers for use as cathodes in Li-ion batteries.

The data in this study are related to the research article "Core-shell electrospun and doped LiFePO/FeS/C composite fibers for Li-ion batteries" [1]. Core-shell LiFePO/FeS/C composites fiber were prepared via an electrospinning method for use as cathodes in Li-ion batteries. The data presented in this paper showed the effect of electrospinning parameters, including applied voltage, solution flow rate, the concentration of polyvinylpyrrolidone (PVP) (wt%) and a mixed PVP/PEO (polyethylene oxide) (w/w%) polymers on the morphological properties of composites fibers.
