Abstract: 

The effect of the electrode sizes, the cell design and the compression force of the electrode modules on the impedance and discharge characteristics of lithium-sulfur cells was studied. It was shown that Swagelok and pouch cells with identical electrodes have different electrochemical characteristics – charge transfer resistance, discharge capacity and cycling duration. It was found that the discharge capacity at the first cycle of Swagelok and pouch cells differs by 20% approximately. The capacity of pouch cells decreases faster during cycling. The cycling of pouch cells in a compressed state (similar to Swagelok cells) does not improve the electrochemical characteristics of pouch cells.
