Silisyum nanotoz yüzeyleri, poliakrilonitril (PAN) polimerinin pirolizi ile amorf karbon ile kaplanmıştır. Amorf
karbon kaplanmış siliyum tozların (Si-C) mikroyapı incelemeleri taramalı elektron mikroskobu (SEM) ile
gerçekleştirilmiş ve geçirimli elektron mikroskobu (TEM) ile karbon kaplama kalınlığı tayin edilmiştir. Enerji dağılım
X-ışınları spektroskopisi (EDS) ile Si-C tozlarının elementel analizleri yapılmıştır. Si-C tozlarının yapısal ve faz
analizleri X-ışınları difraktometresi (XRD) ve Raman spektroskopisi ile incelenmiştir. Üretilen Si-C tozlar bakır akım
toplayıcı üzerinde elektrot olarak hazırlanmış ve CR2016 düğme tipi hücreler kullanılarak 200 mA/g sabit akım
yoğunluğunda elektrokimyasal testleri gerçekleştirilmiştir. Elektrokimyasal test sonuçlarına göre, karbon kaplama
işlemi silisyum anotların hacim genleşmesinden kaynaklı problemleri azaltarak elektrokimyasal davranışlarını
iyileştirmiş ve 30 çevrim sonunda yaklaşık 770 mAh/g deşarj kapasitesi göstermiştir.

Synthesis, characterization and electrochemical performance of core/shell structured carbon coated silicon powders for lithium ion battery negative electrodes

Öz

Surface of nano silicon powders were coated with amorphous carbon by pyrolysis of polyacronitrile (PAN) polymer.
Microstructural characterization of amorphous carbon coated silicon powders (Si-C) were carried out using scanning
electron microscopy (SEM) and thickness of carbon coating is defined by transmission electron microscopy (TEM).
Elemental analyses of Si-C powders were performed using energy dispersive X-ray spectroscopy (EDS). Structural
and phase characterization of Si-C composite powders were investigated using X-ray diffractometer (XRD) and Raman
spectroscopy. Produced Si-C powders were prepared as an electrode on the copper current collector and
electrochemical tests were carried out using CR2016 button cells at 200 mA/g constant current density. According to
electrochemical test results, carbon coating process enhanced the electrochemical performance by reducing the
problems stem from volume change and showed 770 mAh/g discharge capacity after 30 cycles.
