| 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 the 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. |
