Abstract: The discharge and cyclic voltammetry behavior of a variety of zeolites as cathodeof lithium secondary cell have been studied by coulometric titration,infrared absorptionspectrosoepy and X-ray diffractometry. It was found that in the course of discharge lithiumis electrochemically intercalated into compound at discharge depth x<3.4mol.The intercala-tion free energy of Li into NaA zeolite was found to be -231kJ/mol (25℃).The chemicaldiffusion coefficient of lithium in LixNaA(x=0.17~0.69)was determined to be about 1×10-9~1×10-10cm2/s at room temperature.

Key words: lithium-zeolite cell, intercalation, electrochemical behavior
