International Classification:

H01M 8/0245
H01M 8/0239
H01M 8/18

Abstract:

An ionically conductive asymmetric composite membrane for use in redox flow battery, fuel cell, electrolysis applications and the like is described. It comprises a microporous substrate membrane and an asymmetric hydrophilic ionomeric polymer coating layer on the surface of the microporous substrate layer. The coating layer is made of a hydrophilic ionomeric polymer. The asymmetric hydrophilic ionomeric polymer coating layer comprises a porous layer having a first surface and a second surface, the first surface of the porous layer on the surface of the microporous substrate layer and a nonporous layer on the second surface of the porous support layer. The microporous substrate membrane is made from a different polymer from the hydrophilic ionomeric polymer.

Abstract:

Stable and high performance positive and negative electrolytes compositions to be used in redox flow battery systems are described. The redox flow battery system, comprises: at least one rechargeable cell comprising a positive electrolyte, a negative electrolyte, and an ionically conductive membrane positioned between the positive electrolyte and the negative electrolyte, the positive electrolyte in contact with a positive electrode, and the negative electrolyte in contact with a negative electrode. The positive electrolyte consists essentially of water, a first amino acid, an inorganic acid, an iron precursor, a supporting electrolyte, and optionally a boric acid. The negative electrolyte consists essentially of water, the iron precursor, the supporting electrolyte, and a negative electrolyte additive. The iron precursor is FeCl, FeCl, FeSO, Fe(SO), FeO, Fe, FeO, or combinations thereof. The supporting electrolyte is LiCl, NaCl, NaSO, KCl, NHCl, or combinations thereof. The negative electrolyte additive is boric acid or a combination of the boric acid and a second amino acid.

International Classification:

B41M 5/50

US Classification:

428 3238, 156246

Abstract:

The present invention relates to a self adhesive ink jet printable polymer film. The film comprises a polymeric resin and a low surface energy additive that is in a substantially free form. The polymeric resin can be PVC, and the low surface energy additive can be silicone. The film comprising the low surface energy additive exhibits high print resolution and substantially uniform printing quality even after the print surface of the film has been in contact with a back surface of a release liner comprising residual silicone.
