By calcination at 250℃for 16h, LiCl can be highly dispersed into the channels of H-STI prepared from natural CXNB( STI type) zelite discovered in chaina to form a novel guest /host material. XRD, SEM, FT-IR and DTA analysis show that LiCl has been loaded and stabilized in the channels of H-sti. The threshold of LiCl loaded in H-STI is 0. 14g.g, which has been cinfirmed by AC-impedance mesure ments. A sample of LiCl/H-STI with 0.14g/g loading found to possess the highest conductivity, which is four orders of magnitude higher than that of the host (H-STI). This fact indicates that LiCl/H-STI is a promising solid electrolyte.
