Özet:

 

I  n this study, SixSb immiscible composite blend as anode materials have been synthesized  using micron-sized silicone and antimony particles in different compositions through  chemical reduction-mechanical alloying method  CR-MA . The obtained microstructures  have been investigated by X-ray diffraction  XRD  and Scanning Electron Microscopy   SEM  with Energy Dispersive X-Ray analysis  EDX . Spectroscopic characterizations of  the composite materials showed that a traditional intermetallic compound could not be  achieved. However a novel immiscible composite blend system have been developed. One of  the newly prepared composite materials, Si0.65Sb, exhibits an initial capacity of 790 mAh g-1  and a good cyclic stability compared to the pure silicone. The battery performance results  of the micron-sized Si0.65Sb blend system have been compared with the commercially used  graphite and the nano-sized Si/Sb alloy systems. The cycling stability of the micron-sized  Si0.65Sb blend system showed an improvement compared to nano-sized Si/Sb alloy systems.  Moreover its specific capacity is slightly higher than the commercial graphite anode material. These results portray the importance of micron sized Si/Sb system in large-scale applications due to its low cost.
