ABSTRACT

Discharge characteristics of the heat activated battery with CoCl₂–CoF₂ mixtures as a cathode material has been investigated. Composition and morphology of reduction products of the cathode materials have been determined. It was found that the use of mixtures instead of individual cobalt halides allows to stabilize the discharge characteristics and decrease of the discharge temperature of electrochemical cell. It was shown that the reduction process of Co²⁺ -ions to metal Co⁰ occurs under the conditions of diffusion control.
