Özet:

 The widespread and expanded applications of rechargeable lithium-ion batteries necessitate the optimization of advanced batteries. LiFePO4 LFP is widely considered a promising cathode material due to its high stability, abundance, and environmental friendliness. In this study, a solution combustion technique was applied to synthesize a carbon-reinforced LiFePO4C composite with improved electrochemical properties for lithium-ion batteries. As raw materials, a low-cost iron III nitrate compound was used along with glycine as fuel. Variable phases in different amounts of fuel mixtures were identified by XRD analyses, and the optimal fuel ratio was determined to be 4:1. It was observed that complete auto-ignition occurred at this fuel ratio. To enhance the electrochemical properties of the obtained LFP, different weight percentages of sucrose as a carbon source were studied parametrically, and galvanostatic charge-discharge tests were performed. The synthesized LFPC sample containing 15 by weight carbon achieved a capacity of 150 mAhg at a C20 current density. The obtained results are promising for the development of cost-effective, high-capacity, long-lasting, and environmentally friendly lithium-ion batteries.

 Şarj edilebilir lityum iyon pillerin yaygın ve genişletilmiş uygulamaları, gelişmiş pillerin optimize edilmesini gerektirmektedir. LiFePO4 LFP, yüksek stabilitesi, bolluğu ve çevre dostu olması nedeniyle geniş ölçüde ümit verici katot malzemesi olarak kabul edilmektedir. Bu çalışmada, lityum iyon piller için iyileştirilmiş elektrokimyasal özelliklere sahip katot malzemesi olarak karbon takviyeli LiFePO4C kompozitinin sentezine dayalı bir çözelti yanma tekniği uygulanmıştır. Hammadde olarak düşük maliyetli demir III nitrat içeren bileşik ile beraberinde yakıt olarak glisin kullanılmıştır. Farklı miktardaki yakıt karışımında değişken fazlar XRD analizleri ile tespit edilmiş ve en optimal yakıt oranının 4:1 olduğu tespit edilmiştir. Bu yakıt oranında otomatik yanmanın tam olarak gerçekleştiği gözlenmiştir. Elde edilen LFPnin elektrokimyasal özelliklerini iyileştirmek için karbon kaynağı olarak ağırlıkça farklı sükroz oranları parametrik olarak çalışılmış ve galvanostatik şarj deşarj testleri gerçekleştirilmiştir. Ağırlıkça 15 karbon içeren sentezlenmiş LFPC numunesi C20 akım yoğunluğunda 150 mAhg kapasiteye ulaşmıştır. Elde edilen sonuçların uygun maliyetli, yüksek kapasiteli, uzun ömürlü ve çevreye duyarlı lityum iyon pillerin geliştirilmesinde umut verici olduğu gözlemlenmiştir.
