| description | Perovskite structural metal oxides as electrode materials present promising and potential properties due to excellent storage characteristics. Herein, series of perovskite type LaMnO _3 nanopowders were synthesized by the ‘sol-gel’ method with a heat treatment at different temperatures (700 °C–900 °C) for different times. The morphology characterization, structures and electrochemical performances were investigated. The preferable sample for electrochemical energy storage device can be obtained at 900 °C with 2 h annealing. Furthermore, to improve the properties of the electrode materials, the samples were combined and rectified with reduced graphene oxide (rGO) and strontium (Sr), respectively. The results indicate that the rGO/Sr-doped LaMnO _3 oxide materials have excellent electrochemical properties. These findings are beneficial for the selection and preparation of electrode materials. |
