A design for zincchlorine batteries

An alternative design for a zincchlorine electrical energy storage system is described. It is proposed that operation under higher than normal pressures may be advantageous. It is shown that suitable pressures can be built up in the cell during charging. Measurements of the vapour pressure of chlorine over chlorine hydrate are reported and it is shown that chlorine hydrate at usual room temperatures is capable of providing the flow rates required for optimum current. A schematic design is suggested for pressure operated Zn/Cl2 cells. Safetly considerations are briefly discussed.
