Abstract
Official abstract text for this publication.
The present invention relates to a quinone polyhalide flow battery, wherein a positive electrolyte is a mixed solution of hydrochloric acid and sodium bromide, and a negative electrode is a mixed solution of hydrochloric acid and anthraquinone. The problems that the cost of a quinone bromine flow battery is relatively high and the voltage of the battery is relatively low are improved.
First claim
Opening claim text (preview).
We claim: 1. A quinone polyhalide flow battery, comprising: a battery module, a first reservoir containing a positive electrolyte, a second reservoir containing a negative electrolyte, a first circulating pump that causes the positive electrolyte to circulate between the battery module and the first reservoir, and a second circulating pump that causes the negative electrolyte to circulate between the battery module and the second reservoir, wherein the battery module comprises by two, three, or more than three sections of single cells connected in series; and each single cell comprises a positive electrode, a separator, and a negative electrode, wherein the positive electrolyte is a mixed solution comprising hydrochloric acid and sodium bromide, and the negative electrolyte is a mixed solution comprising hydrochloric acid and anthraquinone, wherein each of the positive electrolyte and the negative electrolyte further comprises a quaternary ammonium salt molecular bromine complexing agent that is N-methylethylpyrrolidinium bromide (MEP) or N-methylethyl morpholinium bromide. 2. The quinone polyhalide flow battery according to claim 1 , wherein the positive electrolyte is a mixed solution of 0.5-2 M of hydrochloric acid and 0.5-2 M of sodium bromide. 3. The quinone polyhalide flow battery according to claim 1 , wherein the negative electrolyte is a mixed solution of 0.5-2 M of hydrochloric acid and 0.5-1 M of anthraquinone. 4. The quinone polyhalide flow battery according to claim 1 , wherein a concentration of the quaternary ammonium salt molecular bromine complexing agent is 0.1-1 M. 5. The quinone polyhalide flow battery according to claim 1 , wherein the positive and negative electrode are made of activated carbon felt. 6. The quinone polyhalide flow battery according to claim 1 , wherein the separator is a membrane. 7. The quinone polyhalide flow battery according to claim 1 , wherein the single cell further comprises a positive end plate and a negative end plate.
