Abstract

The technology of lithium-ion batteries (LIBs) is widely regarded as one of the most promising energy sources. The main problem of LIBs now is having comparably low capacity and fast capacity fading. Therefore, our goal is to obtain a high capacity and good stability. At the same time, simple synthesis method and cheap source materials are preferred. Based on existing literature, graphene, metal oxides and Si are most popular anode materials for LIBs. Therefore, Si-based, tin-based, and composite of graphene oxide and FeCl₃ may display good performance.

During my study, I had explored the electrodeposition of Sn layer on copper foil through electrodeposition and anodization methodologies. In addition, SiO₂ coating on Carbon nanotubes (CNTs) was also studied via mild coating method. Besides, we aim to investigate the relationship between materials preparation and LIBs performance. My future research work will include synthesis and characterization of Fe₂O₃/RGO composites and preparation and characterization of LIBs. Batteries using previously prepared materials (SnO₂ and SiO₂- based materials) will also be investigated.
