Abstract

The discharge characteristics of the batteries of thermally activated chemical current sources containing CoCl2–CoF2 mixtures as positive electrodes are studied. The compositions and morphologies of the reduction products of the cathodic materials are determined. The use of the mixtures instead of individual cobalt halides makes it possible to stabilize the discharge characteristics and to decrease the discharge temperature of the current source battery. The reduction of Co2+ to metallic Co0 occurs under diffusion-controlled conditions.

在热活化化学电流源中电还原氯化钴(II)和氟化钴(II)混合物

摘要

研究了以CoCl 2 -CoF 2混合物为正极的热活化化学电流源电池的放电特性。确定阴极材料的还原产物的组成和形态。使用混合物代替单独的卤化钴使得可以稳定放电特性并降低电流源电池的放电温度。Co 2+还原为金属Co 0在扩散控制的条件下发生。
