Synthesis and electrochemical study of CoNi2S4 as a novel cathode material in a primary Li thermal battery
Abstract
In this work CoNi<sub>2</sub>S<sub>4</sub> was investigated as a candidate cathode material for Li thermal batteries. The CoNi<sub>2</sub>S<sub>4</sub> 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, Co<sub>3</sub>S<sub>4</sub> and Co<sub>9</sub>S<sub>8 </sub>of the discharge mechanism were confirmed using powder X-ray diffraction. CoNi<sub>2</sub>S<sub>4</sub> exhibits two voltage plateaus vs Li<sub>13</sub>Si<sub>4</sub> at 500◦C, one at 1.75 V and the second at 1.50 V. CoNi<sub>2</sub>S<sub>4</sub> has an overall capacity of 318 mA h g−1 from OCV 2.58 V to 1.25 V vs Li1<sub>3</sub>Si<sub>4</sub> which is comparable to that of the well-known metal disulfides
