Several aspects of sorption behavior of alkali metal-graphite intercalation compounds were described. Dependence of hydrogen-sorption capacity of potassium-graphite intercalation compounds (K-GICs) on the potassium concentration of KGICs was found to be analogous to those of resistivity and conduction electron spin resonance (CESR) g-value of the K-GICs. Host effect on the hydrogen-sorption behavior of CsC24 was also described. The saturated amount of sorption increased with heat-treatment temperature (HTT) of the host carbons. It was confirmed that H2 was able to be sorbed even for CsC24 prepared from less graphitized carbons such as HTT-1300. The change of electrical resistivity (conductivity) and CESR spectra of alkali metal-graphite intercalation compounds (AM-GICs) during sorption of ammonia was also described.
