In this thesis, optimization, preparation and evaluation of cathode electrodes based on carbon-PTFE-metal Nano composites (containing Cu and Cu/rGO nanoparticles as the Nano catalysts) in the Li/SOCl 2 battery were investigated. Then, the performance of the mentioned electrodes against the common commercial batteries, in the lithium thionyl chloride battery, and in the reduction reaction of SOCl 2 was investigated. TFE/carbon composites with different weight values of PTFE (10%, 20%, 25%, 30%, 35%, 40%, and 50%) were synthesized and the results showed that among the carbon Nano composites, a composite of acetylene black containing 40% wt of Teflon in the LiAlCl4/SOCl 2 had the best performance (exemplar: the cathodic peak of 7 mA). Also, the electrochemical results showed that the current power for the acetylene black is 175 mW and has a high potential in the reduction of thioyl chloride in comparison with the other carbon samples (Vulcan and CNT). SEM and the mapping images showed Cu particles were not dispersed uniformly in the carbon/PTFE composites by mechanical approach, while in the sample in which the Cu particles coated onto the rGO, the Nano catalyst was good dispersed in the Carbon/PTFE composites. The electrochemical behavior of the prepared battery has a good compatibility with commercial batteries and the OCVs for composites were about 3.84 V. The morphology and structure of the composites have been studied using XRD, TEM, and SEM techniques.
