ABSTRACT:
A simple, inexpensive and trouble-free method of controlling the chlorine feed to a metal-chlorine battery system from a source of chlorine hydrate includes circulating aqueous electrolyte from an electrode compartment through a pump and recycled back to the electrode compartment, taking off a portion of the electrolyte, passing through a container of chlorine hydrate from which it releases chlorine and water, the chlorine generation increasing the pressure in the container, controlling the flow of electrolyte to the container, allowing the chlorine generated to flow from the container to the recycle line and back to the electrode compartment, which diminishes the pressure in the container, at which time electrolyte is again admitted to it, and the steps are continually repeated during the discharging of a battery system. An apparatus for carrying out the process of the invention includes a check valve between the pump and the container of hydrate which closes, preventing admission of the electrolyte to the container when the pressure increases enough to threaten to force the contents back through the line in which the check valve is located.
