제목 Characterization of Li2MnSiO4 Cathodes Material in Lithium Reachargeable Batteries
초록  Silicon is an element with natural abundance and non toxic characteristics. And orthosilicate is one class of the attractive polyanions wth intrinsic thermal stability. The lithium transition-metal orthosilicates, Li2MSiO4 (M=Fe, Mn and Co) have been proposed as a new clas of high-capacity lithium ion battery cathode. Li2MnSiO4 was synthesized by a sol-gel method from lithium acetate, manganese, and tetraethyl orthosilicate precursors. Then, these precursors were dissolved in water/ethanol, dried at 80 oC and placed into a tubular furnace at various temperature and time under an N2 atmosphere to get the resultant product. The structural properties of Li2MnSiO4 were carried out using an X-ray diffraction (XRD). The morphological feature was investigated using a scanning electron microscope (SEM). The electrochemical characterization of the products was carried out between 2.0 and 4.7 V in coin cell.
