硫化铁热电池初始峰压产生机理研究

Study on initial voltage of FeS_2 thermal battery

分析了黄铁矿的杂质元素含量;利用正极掺杂,实验了可能产生热电池初始峰压的Fe、S杂质及化合物,分析了导致峰压各化合物的两种来源,解释了硫化铁热电池正极制备中削峰工艺的作用原理是还原了三价铁杂质。

The contents of impurity elements in pyrite were analyzed.The impurities of Fe and S were tested for producing initial voltage with the method of cathode adulteration.Two sources of compounds which brought on initial voltage were construed.The principle of impairing initial voltage procedure in preparation cathode material was deoxidizing trivalent iron impurity.
