| 中文摘要 | Here we report the characteristics of mutual-substituted bi-phase composites with nominal formula of (1 - x)LiMnPO4 center dot xLi(3)V(2) (PO4)(3)/C (x = 0.01, 0.03, 0.05, 0.1, 0.15, 0.2, 0.3, 0.4, 0.5). According to the results of refinement and XPS, as x >= 0.03, the prepared material becomes the binary mixture of LiMn1-yVyPO4 and Li3V2-zMnz(PO4)(3) where y is probably ramped rapidly and z is relatively stable. Tested between 2.5-4.4 V vs. Li/Li+, the electrochemical performance of the synthetic composites presents the Plough-shape tendency as the increase of Li3V2(PO4)(3)'s nominal ratio. The discharge capacity is dropped from 99 mAh g(-1) of 0.99LiMnPO(4)center dot 0.01113V(2)(PO4)(3)/C to 69 mAh g(-1) for 0.95LiMnPO(4)center dot 0.05Li(3)V(2)(PO4)(3)/C, then recuperated, and finally stabilized at similar to 125 mAh g(-1) for the samples with 20% Li3V2(PO4)(3) or more. Compared with LiMnPO4/C, the "gaining point" of composites is incorporating 20% Li3V2(PO4)(3), probably corresponding to similar to 8% vanadium substitution based on refinement results.
