Abstract

Our research on new cathode nano-materials for advanced lithium batteries has focused on the hydrothermal method for synthesis. We have synthesized two novel manganese vanadium oxides using the hydrothermal reactions of vanadium (V) pentoxide, [N(CH₃)₄]MnO₄, and MnSO₄ with an organic templating cation at 165°C. The δ-type [N(CH₃)₄]_zMn_yV₂O₅·nH₂O has a monoclinic structure, a=11.66(2) angstrom, b=3.610(9) angstrom, c=13.9(4) angstrom, β=108.8(2)°. It has a disordered V₂O₅ double layer and the Mn and N(CH₃)₄ ions reside between the layers. The γ-type MnV₂O₅ is orthorhombic, belongs to the space group Pnma, a=9.7585(2) angstrom, b=3.5825(1) angstrom, c = 11.2653(2) angstrom. 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.
