Manganese vanadium oxides as cathodes for lithium batteries

MnxV2O5 (x=0.02, 0.04, 0.09, and 0.19) was prepared by controlling the manganese content in V2O5 using an ion exchange resin via the sol-gel process and examined with an emphasis on characterizing its electrochemical properties, such as the current–voltage correlation, cycling performance, rate capability, and impedance characteristics. The electrochemical performance of the Mn-doped-V2O5 was better than the undoped vanadium pentoxides. The specific capacity and average voltage of the V2O5 cathodes increased gradually as the manganese doping concentration increases.
