Production of Sn-Co / CNT Composite Anodes by Pulse Current Method for Lithium Ion Batteries

Öz

The graphite is an anode material which is widely used as commercially for li-ion batteries. Because of having low capacity, graphite led to investigate alternative materials with higher capacity and good cycle stability. As an alternative to graphite, tin based electrode materials are of interest due to their high capacity values. In this study Sn-Co/MWCNT composite electrodes were deposited on copper substrates by using pulse current (PC) plating technique. The effect of peak current density to the battery performance was studied. As a result of studies, the best result was obtained in the coatings which were prepared at 60 mAcm-2 peak current density.

Lityum İyon Piller için Pulse Akım Yöntemi ile SnCo/CNT Kompozit Anotların Üretimi

Öz

t- Li iyon pilleri için anot malzemesi olarak grafit, ticari olarak yaygın kullanılan malzeme olmasına rağmen, düşük kapasiteye (372 mAh g-1 ) sahip olması daha yüksek kapasiteye ve iyi çevrim kararlılığına sahip alternatif malzemeleri araştırmaya sebep olmuştur. Grafite alternatif olarak kalay esaslı elektrot malzemeleri yüksek kapasite değerlerinden dolayı ilgi çekicidir. Bu çalışmada Sn-Co/ÇDKNT kompozit elektrotlar bakır altlıklar üzerine pulse elektrolitik kaplama yöntemi ile biriktirilmiştir. Pik akım yoğunluğunun pil performansına olan etkileri incelenmiştir. Yapılan çalışmalar sonucunda en iyi sonuç, 60 mAcm-2 pik akım yoğunluğunda, üretilen kaplamalarda elde edilmiştir.
