The elastic deformation of host layers is calculated by constructing a model where the host layers, regarded as continuous two-dimensional elastic sheets, are infinitely stacked and compressible intercalants, represented by harmonic springs, are intercalated into them. If we treat the intercalants as being rigid relative to the soft host layers in the stage-1 graphite intercalation compound, LixC6 (0<=x<=1), the calculated average gallery spacing agrees well with the experiments, without using any adjustable parameter.
