145074 - C60 Embedded Sioc Electrospun Fibermat as a High-Capacity Electrode Material in Li-Ion Batteries. 

Precursor-derived silicon oxycarbide also known as PDC SiOC, has gained attention as a possible high-capacity anode material for Li-ion storage systems. The defining characteristic of PDC, the polymer processing and pyrolysis route, enables chemical interaction with a range of nano-precursors and nanofiller phases to develop low-dimensional composite structures such as coatings, and fibers that are difficult to obtain in conventional sintered ceramics. In this study, buckminsterfullerene, or C₆₀, was induced to 1,3,5,7-tetramethyl-1,3,5,7-tetravinyl-cyclotetrasiloxane (TTCS) hybrid precursor as a filler phase in order to generate electrospun fibermats. These fibermats then underwent a low and high heat temperature treatment to transform into C₆₀ reinforced SiOC ceramic composite. Using electron microscopy and other spectroscopy methods, the morphology and chemical evolution of the as-spun, stabilized, and ceramicized fibermats were verified. In comparison to neat C₆₀, SiOC, and carbon fiber electrodes, C₆₀ reinforced fibermats exhibit significantly better reversible capacity, high cycling efficiency, and superior rate capability with low capacity decay at high currents when tested as the self-supporting working electrode in a Li-ion half-cell.
