Abstract: This electrochemical cell uses zinc and either chlorine or bromine as the primary reactants, with a molten, non-aqueous zinc halide electrolyte. During charging of the cell, growth of dendrites on the zinc electrode is controlled by operating the cell continuously or intermittently at a temperature above the melting point of zinc, thereby positively preventing such growth; or by operating at such temperature that incipient dendrites are melted by heat generated by the charging current. That current may be intermittently increased to insure such dendrite control. In a large battery of cells utilizing chlorine as the halogen, excess halogen gas developed during charging of the battery is compressed and liquefied to facilitate external storage, and a large portion of the energy required for compression is recovered upon expansion of the gas during battery discharge.

Abstract: A secondary battery utilizing hydrogen and halogen as primary reactants comprises inert anode and cathode initially contacting an aqueous solution of an acid and an alkali metal bromide. The hydrogen generated during charging of the cell is stored as gas, while the bromine becomes dissolved predominantly in the lower layers of the acid electrolyte. Preferred components comprise phosphoric acid and lithium bromide.
