Abstract

We show that lithium intercalation in

{Li}_{x} {Mo}_{6} {Se}_{8}

is described accurately by mean-field solutions to a single-parameter lattice-gas model. We present mean-field fits to the inverse derivative

\frac{dx}{dV}

of the voltage

V

of

\frac{Li}{{Li}_{x} {Mo}_{6} {Se}_{8}}

cells at several temperatures. This is apparently the first fully quantitative description of

\frac{dx}{dV}

for an intercalation system and the first realization of a three-dimensional mean-field lattice gas.
