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.
