Abstract

In this work, heterogeneous carbon/N-doped reduced graphene oxide wrapping LiMn 0.8 Fe 0.2 PO 4 (LMFP/C/N-rGO) composites were synthesized successfully via a simple solvothermal method coupled with further calcination. The composites were characterized by XRD, SEM, TEM and XPS, and their electrochemical properties were evaluated by CV, EIS and charge-discharge test. The LiMn 0.8 Fe 0.2 PO 4 /C particles were uniformly grown on the surface of three-dimensional N-doped reduced graphene oxide (N-rGO). The interconnected N-rGO among LMFP particles and amorphous carbon coating on LMFP surface build a continuous conductive network which helps the fast transmission of electron. Lithium ion batteries with LMFP/C/N-rGO exhibit superior discharge capacity, rate capability and cycling stability, bringing a broad prospect for the future applications.
