Cells wound-anode construction

Mallory produce special mercury cells, based on the wound-anode construction principle, which are particularly suitable for use at lower temperatures than those recommended for normal mercury cells. Thus Mallory types RM1438, RMI450R and RM2550R operate efficiently at a temperature 15°C lower than the standard mercury cells.

Both the lithium sulfur dioxide (Li-SO and lithium thionyl chloride (Li-SOCy cells may be classified as liquid cathode systems. In these systems, S02 and SOCl2 function as solvents for the electrolyte, and as the active materials at the cathode to provide voltage and ampere capacity. As liquids, these solvents permeate the porous carbon cathode material. Lithium metal serves as the anode, and a polymer-bonded porous carbon is the cathode current collector in both systems. Both cells use a Teflon-bonded acetylene black cathode structure with metallic lithium as the anode. The Li-S02 is used in a spirally wound, jelly-roll construction to increase the surface area and improve... 

The construction of organic lithium cells is somewhat different from that of mercury and alkaline manganese cells. A lithium foil anode, a separator and a carbonaceous cathode are spirally wound together. This assembly is placed in a steel case, and the anode and eathode are eonnected with welded tabs to the case and top assembly. Since the electrolyte is non-aqueous, there is no hydrogen gas evolved during discharge. The...
