An olivine LiFe0.5Mn0.5PO4/rGO composite cathode material prepared from manganese ore tailings with excellent lithium storage performance
The high-value utilization of manganese ore tailings is of great significance for saving mineral resources and achieving environmental protection. Herein, an olivine LiFe0.5Mn0.5PO4/rGO composite is synthesized by a simple precipitation method and subsequent high-temperature calcination process using the manganese ore tailings as raw material. The prepared LiFe0.5Mn0.5PO4/rGO composite exhibits superior cycling stability (with 113.5 mAh·g−1 after 300 cycles at 1.0C (1.0C = 170 mA·g−1)) and superior rate performance (with 65.6 mAh·g−1 at 10.0C). Ex-situ XRD and electrochemical impedance spectroscopy (EIS) analyses evidence that the LiFe0.5Mn0.5PO4/rGO material has excellent structural stability and electrochemical reversibility during charge and discharge processes. Furthermore, the LiFe0.5Mn0.5PO4/rGO//graphite full Li-ion battery also exhibits excellent cycling stability indicating its potential commercialization value.
