Fe2O3@Ag nanocomposites by hydrothermal process for anode materials of lithium ion batteries |
| 초록 |
Fe2O3 is extensively used in industrial production for products used daily life. Due to its high theoretical capacity of 900 mAhg-1 has received a promising electrode material for lithium ion batteries (LIB) with multiple electron transfer per metal cluster. However, lithiation and delithiation of Fe2O3 can effectively reduce the obviously volume change that result in capacity fade and poor performance. In this study, Fe2O3 nanoparticles have been synthesized by using a one-step hydrothermal method. Electrochemical impedance spectroscopy (EIS) was used to investigate the as-prepared and cycled cells from 1cycle to 100 cycles in the charged state. The rate performance of hematite Fe2O3 nanoparticles was measured using a rate capability test. EIS showed that Fe2O3 and Fe2O3@Ag@carbon nanoparticles compare to its submicron size had higher lithium diffusion coefficients during the charging. |
