Abstract
Methods and systems are provided for manufacturing a membrane separator for a redox flow battery. In one example, the membrane separator is fabricate by a calendering process. The membrane separator may be configured with a polymer network to provide selectivity for ion transport across the membrane separator. The membrane separator may be further adapted with an integrated spacer in contact with a negative electrolyte.
Claims20
A method for manufacturing a redox flow battery, comprising:
- combining and treating chemical ingredients of a membrane separator;
- forming a sheet from the combined chemical ingredients;
- molding ribs onto a surface of the sheet;
- and
- infiltrating the sheet with a cross-linked polymer network.

A separator for a redox flow battery, comprising:
- a fluid-impermeable, ionically conductive membrane;
- and
- ribs molded into a surface of the fluid-impermeable, ionically conductive membrane.
A redox flow battery, comprising;
- a first battery cell storing a positive electrolyte and a negative electrolyte within a chamber of the first battery cell;
- a first positive electrode submerged in the positive electrolyte and a first negative electrode submerged in the negative electrolyte of the chamber of the first battery cell;
- and
- a membrane separator arranged in the chamber of the first battery cell between the positive electrolyte and the negative electrolyte and in contact with the first negative electrode, the membrane separator adapted with an ion selective polymer network disposed in pores of the membrane separator, a surface of the membrane separator forming an integrated negative spacer in contact with the negative electrolyte.
