dc.description.abstractIn this work CoNi2S4 was investigated as a candidate cathode material for Li thermal batteries. The CoNi2S4 was synthesized by a solid state reaction at 550◦C in a sealed quartz tube. Neutron powder diffraction was utilized to confirm normal spinel structure up to 200◦C, however, there was cation disorder above this temperature. The electrochemical properties of the batteries were investigated at 500◦C by galvanostatic discharge to elucidate the mechanism and the products NiS, Co3S4 and Co9S8 of the discharge mechanism were confirmed using powder X-ray diffraction. CoNi2S4 exhibits two voltage plateaus vs Li13Si4 at 500◦C, one at 1.75 V and the second at 1.50 V. CoNi2S4 has an overall capacity of 318 mA h g−1 from OCV 2.58 V to 1.25 V vs Li13Si4 which is comparable to that of the well-known metal disulfides
