摘要：
The monoclinic Li3+xFe2-xMnxII(PO4)3(x=0-0.1), Li3Fe1.95Mn0.05III(PO4)3and Li2.95Fe1.95Mn0.05IV(PO4)3cathodes were synthesized by solid state reaction. The synthesized powders were ball-milled with acethylene carbon to reduce the particle sizes and improve the electronic conductivity of the active materials. The galvanostatic charge/discharge test and the cyclic voltammetry (C-V) revealed that all of them had two plateau potentials of Fe3+/Fe2+couple vs. Li/Li+at 2.8 and 2.7 V upon discharge. The plateau potential of Mn3+/Mn2+at 3.5 V was observed in Li3+xFe2-xMnxII(PO4)3and Li3Fe1.95Mn0.05III(PO4)3cathodes. Furthermore, the Mn doping was demonstrated to be able to improve the electrochemical performances of the cathodes. In all the samples, the Li3.05Fe1.95MnII0.05 (PO4)3/C cathode showed the best electrochemical performances and possessed the discharge capacities of 110 mAh/g at C/20 and 66 mAh/g at C/2.
