Abstract

We have synthesized novel nickel and manganese vanadium oxides using the hydrothermal reactions of vanadium(V) pentoxide, Ni(CH₃COO)₂, and MnSO₄ with an organic templating cation at 165°C. The [NH₂(CH₂)₂NH₂]₂NiV ₆O1₄ has a monoclinic structure. It has some disordered V and O atoms in the V₆O₁₄ layer, which appear to be very close to each other with occupation factor around 0.5. The disordered model was decomposed for two ordered configurations, which differ in the stacking of the layers. The (Mn⁺²)₆(Mn⁺³)_1.2/3z(OH) _3(1.z)(VO₄)₃[(VO₄) _1.2z(V₂O₇)_z] (z≈0.1) phase has a hexagonal pipe morphology. These compounds were also characterized by electron microprobe, FTIR and TGA. They reacted readily with lithium, and their electrochemical behavior in lithium cells was determined.
