Lithium Insertion Behaviour of (H₃N(CH₂)₃NH₃)[V₄O₁₀]

抄録

Electrochemical behaviour of (NH₃(CH₂)₃NH₃)_y[V₄O₁₀] (1) was investigated as lithium insertion host. By thermal treatment above 250°C it was possible to remove the organic constituent in the interlayer from the compound (1) at 250°C, and the original layer structure was maintained up to about y>0.75 in (NH₃(CH₂)₃NH₃)_y[V₄O₁₀]. Lithium ions were inserted electrochemically in the compound (1), and amount of lithium inserted in the interlayer increased as y decreased. This increase was caused by increase in the available sites for lithium ions and largely by enhancement of diffusion rate in the interlayer.
