Abstract
A redox flow battery includes a positive electrolyte tank container which houses a positive electrolyte tank for storing a positive electrolyte; a negative electrolyte tank container which houses a negative electrolyte tank for storing a negative electrolyte; and a battery container which houses a battery cell including a positive electrode, a negative electrode, and a membrane, a positive electrolyte circulation mechanism configured to supply and circulate the positive electrolyte to the battery cell, and a negative electrolyte circulation mechanism configured to supply and circulate the negative electrolyte to the battery cell.
Claims13
A redox flow battery comprising:
- a positive electrolyte tank container which houses a positive electrolyte tank for storing a positive electrolyte;
- a negative electrolyte tank container which houses a negative electrolyte tank for storing a negative electrolyte;
- and
- a battery container which houses a battery cell including a positive electrode, a negative electrode, and a membrane, a positive electrolyte circulation mechanism configured to supply and circulate the positive electrolyte to the battery cell, and a negative electrolyte circulation mechanism configured to supply and circulate the negative electrolyte to the battery cell,
- wherein the battery container is placed on the roof of the positive electrolyte tank container and the negative electrolyte tank container,
- wherein, when the redox flow battery is viewed from the top, a first short side of the battery container overlaps with an outer long side of the positive electrolyte tank container and a second short side of the battery container overlaps with an outer long side of the negative electrolyte tank container, and
- wherein long sides of the battery container are the same size or smaller than long sides of the positive electrolyte tank container and long sides of the negative electrolyte tank container, and
- wherein the short sides of the battery container are the same size or smaller than short sides of the positive electrolyte tank container and short sides of the negative electrolyte tank container.
