제목 Effect of Surface Treatments on Electrochemical Performances of Pitch-Coated Silicon Composite as Lithium-Ion Batteries Anode
초록 In this work, the effect of interface treatment on pitch coated-layer was formed macroporous that was investigated in electrochemical performance and structural properties of carbonized pitch coated silicon composites. Pitch coated silicon composites were synthesized by mixing of silicon powders and petroleum pitch. And heat treatment as a function of carbonization temperature. The morphologies of composites were observed by scanning electron microscope. And structure of composites was examined using XRD method. The obtained pitch coated silicon composites were assembled as half cell anodes for lithium ion battery which was investigated in their electrochemical properties such as the initial efficiency, the initial discharge capacity and cycle life. From the results, these composites were explained that suitable macroporous size of anode composites interface played an important role in improving initial discharge capacity and cycle life.
