摘要:
A metal-halogen secondary battery has a high state of charging and a capability of storing a large electric power at a high density. In the secondary battery the electrolyte pressure in the positive electrode chamber is higher than the electrolyte pressure in the negative electrode chambers. The metal ions in the positive electrode chambers are permeated into the negative electrode chambers and reduced, and the halogen ions in the negative electrode chambers are also permeated into the positive electrode chambers and oxidized thereby contributing to the storage of the electric power.

摘要:
A secondary battery utilizing a zinc bromide electrolyte has an electrolyte which is composed of a first solution including zinc bromide and a complexing agent which forms a bromide complex from the bromide ions to precipitate the complex in the electrolyte, and a second solution of a zinc compound which is selected from groups of compounds which decompose at a higher voltage than the first solution during battery charging. The concentrations of the first and second solutions are regulated for providing a concentration of zinc ions which are generated from the first and the second solutions at least 0.5 mol/l higher than bromide ions which are generated from the first solution.
