Abstract
A redox flow battery includes a battery cell; a positive electrolyte tank and a negative electrolyte tank configured to store therein a positive electrolyte and a negative electrolyte, respectively; a positive electrolyte circulation path and a negative electrolyte circulation path each configured to allow a corresponding one of the electrolytes to circulate between a corresponding one of the tanks and the battery cell; and a communicating tube including a tube immersed at one open end thereof in the positive electrolyte, stretched at an intermediate portion thereof above levels of both the electrolytes, and immersed at the other open end thereof in the negative electrolyte.
Claims7
A redox flow battery comprising:
- a battery cell;
- a positive electrolyte tank and a negative electrolyte tank configured to store therein a positive liquid electrolyte and a negative liquid electrolyte, respectively;
- a positive electrolyte circulation pipe and a negative electrolyte circulation pipe each configured to allow a corresponding one of the liquid electrolytes to circulate between a corresponding one of the tanks and the battery cell;
- a communicating tube including a tube having one open end thereof fully immersed in the positive liquid electrolyte, an intermediate portion thereof stretched above levels of both the liquid electrolytes, and the other open end thereof fully immersed in the negative liquid electrolyte;
- an introducing tube separate from the positive and negative electrolyte circulation pipes and configured to connect at least one of the positive electrolyte circulation pipe and the negative electrolyte circulation pipe to the communicating tube;
- and
- an open-close valve configured to open and close the introducing tube.
