Abstract
Metals and metal oxides as anode materials for Li-ion batteries and supercapacitors are of significant interest to many potential technologies because of their high theoretical capacity value, low price, and environmentally friendly features. In spite of these considerable benefits and ongoing progress in the field, momentous challenges exist, especially structural disintegration due to volume expansion of electrode materials. In this study, the direct synthesis of electrospun tin based composite with CNF prepared directly on a nickel foam current collector using the electrostatic spray deposition (ESD). This binder free approach provides some advantages such as the controllability of the nanostructure morphology and scalable manufacturing capabilities. The electrochemical performance of the tin-based composite synthesized by electrostatic spray deposition as an anode material for Li-ion batteries were evaluated by charge-discharge experiments. The composite material showed large discharge capacity of 1117.5 mAhg-1 after 30 cycles and also a high rate capability. In this study, the cycling stability and rate capability of samples is presented in a half-cell assembly against Li/Li+. Moreover, the feasibility of creating anodes and the results of characterization of the active materials are discussed.
