Metal halogen battery construction with improved technique for producing halogen hydrate

An improved method for producing halogen hydrate in a metal halogen electrical energy storage system, said system being comprised of,

• at least one cell having a positive electrode and a negative electrode separated by aqueous electrolyte containing the material of said metal and halogen,
• store means wherein halogen hydrate is formed and stored as part of an aqueous material having a liquid level at an upper part of the store means,
• means for circulating electrolyte through the cell, conduit means for transmitting halogen gas formed in the
• cell to a hydrate forming means associated with the store means,
• said hydrate forming means including,
• pump means to which there is introduced quantities of said halogen gas and relatively chilled water, said pump means being located in the store means below the liquid level thereof,
• outlet conduit means leading from said pump means and being substantially straight and generally vertically disposed and having an exit discharge into the gas space above the liquid level in said store means,
• said method comprising the steps of,
• introducing halogen gas and chilled water to said pump means to thereby initiate a reaction whereby halogen hydrate is formed during passage through the pump means and the outlet conduit means,
• recovering the halogen hydrate from the exit discharge and storing same in said store means.
