✦ Synopsis

The purpose of the work was to find the dependence of physical and electrical properties of Li/SOCl, cathodes on the type of carbon blacks used in cathode preparation.

Additionally, we tried to evaluate the possible influence of the carbon black type on anode electrical properties.

The separate investigation of cathode and anode electrical properties could be realised by implementing a reference lithium electrode into the Li/SOCI, batteries under investigation.

It is shown that at low frequencies (below 100 Hz) the reference electrode may serve as a relevant tool for distinguishing between the cathode and anode electrical behaviour. Before battery discharge the electrical properties of both electrodes were studied using the impedance spectroscopy as a non-destructive method, while during the discharge the potential drop on each electrode was monitored as a function of time and current. The distribution and composition of discharge products was studied using SEM/EDS analysis.

## Abstract Films were prepared from mixtures of PVAc latex, CB, and natural sodium montmorillonite clay. In the absence of clay, these composites exhibit a percolation threshold of 1.2 vol.‐% CB, which is nearly an order of magnitude lower than that observed for composites prepared using PVAc solu
