Size Controlled Synthesis of Spherical Li2MnSiO4 Cathodes Material in Lithium Rechargeable Batteries |
| 초록 |
Silicon is an element with natural abundance and non toxic characteristics. And orthosilicate is one class of the attractive polyanions with intrinsic thermal stability. The lithium transition-metal orthosilicates, Li2MSiO4 (M = Fe, Mn, and Co), have been proposed as a new class of high-capacity cathode in lithium ion batteries. The synthesis of nanosized spherical SiO2 were performed by a modified Stober process. The spherical Li2MnSiO4 was synthesized by the calcination of the mixture of nanosized SiO2, and lithium and manganese compounds. The particle size of uniform spherical Li2MnSiO4 was controlled by the size of SiO2. The structural properties of Li2MnSiO4 were carried out using an X-ray diffraction (XRD). Their morphological features were investigated using a scanning electron microscope (SEM). The electrochemical characterization of the products was carried out between 2.0 and 4.7V in coin cell. |
