Abstract: A method for producing a waterproof and ion-conducting flexible membrane intended for protecting a metal electrode. It comprises a synthesis by electrically assisted extrusion of compact fibers forming an ion-conducting fiber array comprising a first material. The fiber array defines a first surface and a second surface opposite the first surface. Subsequently, the fiber array is impregnated with a polymer of a second material, to form a metal electrode protection membrane. The fiber array forms paths for conducting ions between the first surface and the second surface and through the second material. The first surface is intended to be in contact with the metal electrode.

Abstract: A redox flow battery is provided having a double-membrane (one cation exchange membrane and one anion exchange membrane), triple-electrolyte (one electrolyte in contact with the negative electrode, one electrolyte in contact with the positive electrode, and one electrolyte positioned between and in contact with the two membranes). The cation exchange membrane is used to separate the negative or positive electrolyte and the middle electrolyte, and the anion exchange membrane is used to separate the middle electrolyte and the positive or negative electrolyte. This design physically isolates, but ionically connects, the negative electrolyte and positive electrolyte. The physical isolation offers great freedom in choosing redox pairs in the negative electrolyte and positive electrolyte, making high voltage of redox flow batteries possible. The ionic conduction drastically reduces the overall ionic crossover between negative electrolyte and positive one, leading to high columbic efficiency.
Abstract: Perfluoropolyether electrolytes have either one or two terminal nitrile groups and an alkali metal salt. The alkali metal salt can be a lithium salt, a sodium salt, a potassium salt, or a cesium salt. The salt can make up between 5 and 30 wt % of the electrolyte composition. Such electrolytes have shown high ionic conductivities, making them useful as lithium cell electrolytes.
