Na_2Mo_(0.1)S_(0.9)O_4(α)和非稀土硫酸盐二元系的相关系和导电性研究

PREPARATION OF a-MoS_3CATHODIC MATERIAL BY MODIFICATIVE METHOD OF AQUEOUS SOLUTION PRECIPITATION AND ITS ELECTROCHEMICAL PERFORMANCE

本文采用XRD、DTA和电测量技术研究了Na_2Mo_(0.1)S_(0.9)O_4(α)和非稀土硫酸盐二元系的相关系和导电性;我们发现在掺有8m/o CaSO_4体系中,280℃时电导率可达到10^(-3)数量级,与掺杂稀土硫酸盐的效果相似,但仍有相变存在;同时还讨论了掺入异价离子后电导率提高很多以及相变存在的原因。

This artical reports on the preparation of a-MoS_3cathodic material and its electrochemial performance. The amorphous molybdenum trisulfide has been prepared by the modificative method of aqueous solution precipitation. The material conductivity, the discharge property of model lithium cell made by a-MoS_3+15％chsrcoal us cathodic material and the cycled voltegeampere curve has been studied.
