LiCl/4A分子筛体系固体电解质的制备与性能研究

A Study on the Preparation and Performance of the Solid Electrolytes of the LiCl/4A Molecular Sieve Series

金属锂作为电池的阳极有许多特殊的优点．利用LiCl在4A分子筛内表面分散制备了一系列导电性较好的LiCl／4A分子筛固体电解质；虽然电导大小随体系不同略有差异，但是电导率都较大．LiCl分子筛体系固体电解质导电率在同样条件下普遍高于β-Al2O3固体电解质1～2个数量级，其中0．64gLiCl／g4A分子筛的电导达最大值，是导电性相当好的固体电解质．

The metal lithium （Li） is used as the anode of a battery which has many specific advantages. Using the surface dispersion principle of LiCl in the molecular sieve 4A, a series of the solid electrolytes of the LiCl/4A molecular sieve with better conductivity is prepared. In the same conditions, the conductivity of the solid electrolytes of the LiCl/4A is higher than that of the solid electrolytes of the β-Al2O3 for 1 - 2 orders in which the conductivity of the 0.64g LiClg 4A molecular sieve reaches the maximum, that can be said a solid electrolytes with good conductivity.
