“…XRD results indicated a hybrid nanocomposite structure expected to provide beneficial properties for electrode applications, since MWCNTs will behave as a buffer phase to prevent electrode disintegration in Li-ion batteries. Various studies have been reported showing this feature of CNTs for ZnO anode materials [4,30].…”

“…The strongest diffraction peak belongs to Carbon (JCPDS, 00-026-1080) for the two samples. All of the other weak diffraction peaks correspond to the planes of hexagonal ZnO (JCPDS 36-1451) and show (100), (002), (101) planes [4].…”

“…As seen from the lattice parameter calculations, in the ZnO/MWCNT/GLY nanocomposite has smaller "a" and larger "c" values than that of the standard values. So, it provides a significant number of oxygen vacancies leading to a reduction of interatomic distances [4]. These results gave very advantageous outcomes to use ZnO/MWCNT nanocomposite, which was produced by chelating with GLY at the solegel synthesis stage, as the anode in the Li-ion battery applications.…”

“…Among transition metal oxides, ZnO features low cost, easy preparation, morphologic diversity, and environmental benignity, among other benefits [3]. ZnO is attractive as a potential substitute for the conventional graphite anode in lithium-ion batteries, as the theoretical capacity (978 mAh g À1 ) has been estimated to be superior to that of graphite (372 mAh g À1 ) [4].…”

“…Karbon kaplama elektrolit ile SnO partiküllerinin doğrudan temasını engel olarak yüzey üzerinde pasivasyon tabakasının oluşumunu geciktirerek çevrimsel kararlılığını geliştirmiştir [20]. [22]. Ancak, şarj ve deşarj işlemleri boyunca anot elektrotunda yüksek oranda hacimsel genleşmelere bağlı olarak hasarların ve tozlaşmaların meydana gelmesi ile partiküller arası temas direncinde artış görülür.…”

ÖZBu çalışmada Li-iyon piller için uyumlu çekirdek olarak kalay (II) oksit anotlar kimyasal indirgeme yöntemi ile sentezlenmiştir. Karbon esaslı kabuk sentezi için mikrodalga destekli karbürizasyon yöntemi kullanılmış ve SnO tozlarının yüzeylerinde ince amorf bir karbon tabakası elde edilmiştir. Üretilen kalay (II) oksit/karbon kompozit elektrotların yüzey morfolojileri Taramalı Elektron Mikroskobu (SEM) ile analiz edilmiş ve yapıların faz bileşenleri X-Işınları Difraktometresi (XRD) ile karakterize edilmiştir. Üretilen kalay (II) oksit/karbon kompozit tozları kullanılarak hazırlanan elektrotlar ile CR2016 test hücreleri hazırlanmış ve elektrotların elektrokimyasal performansı MTI BST8-MA 8 kanallı pil test ünitesinde, oda sıcaklığında 10 mV ve 2,5 V arasında sabit 1C şarj/deşarj şartlarında akım verilerek test edilmiştir. Sonuç olarak, kalay (II) oksit/karbon kompozit elektrot malzemeleri ile 100 çevrim sonrasında 396 mAh g -1 deşarj kapasitesi elde edilmiştir.Anahtar Kelimeler: Kalay (II) oksit, çekirdek/kabuk, kimyasal indirgeme, mikrodalga destekli karbürizasyon, Li iyon pil. The Production and characterization of tin (II) oxide composite anode electrodes for lithium ion batteries ABSTRACTIn this study, the core component of the composite, tin (II) oxide powders synthesized through a facile chemical reduction methods for Li-ion batteries. As the shell structure, surfaces of the as-synthesized tin (II) oxide particles were coated with carbon through microwave assisted carburization process. The surface morphologies and phase components of the as-synthesized tin (II) oxide/carbon composites were investigated via scanning electron microscopy and X-ray diffraction methods, respectively. CR2016 type coin cells were prepared by using tin (II) oxide/carbon composite powders and electrochemical tests were performed at room temperature via 8-channel MTI BST8-MA electrochemical test station between 10 mV and 2.5 V potential range by applying fixed 1 C state of charge conditions. The results have shown that tin (II) oxide/carbon composite structure have significantly improved the specific capacities to 396 mAh g-1 after 100 cycles. sea takimata sanctus est Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam * nonumy eirmod tempor invidunt ut lab ore sit et dolore magna
