摘要： Embodiments in accordance with the present invention encompass a variety of polymers derived from polycyclic olefin monomers, such as hydrocarbon functionalized norbornenes. The polymers so formed function as ionomers and are suitable as anion exchange membrane for fabricating a variety of electrochemical devices, among others. More specifically, the ionomeric polymers used herein are derived from a variety of quaternized amino functionalized norbornene monomers and are lightly crosslinked (less than ten mol %). The membranes made therefrom exhibit very high ionic conductivity of up to 198 mS/cm at 80° C. This invention also relates to using an anion conducting solid polymer electrolyte as the ion conducting medium between the two electrodes and the ion conducting medium within the electrodes acting as the ionic conduit between electroactive material and electrolyte. The electrochemical devices made in accordance of this invention are useful as fuel cells, gas separators, and the like.

摘要： The invention provides a novel anionic polymer useful as a solid electrolyte in a lithium battery. The electrolyte matrix provides directional, flexible, polymeric ion channels with 100% lithium conduction with low-to-no affinity of the matrix for the lithium ion, in part due to the low concentration or absence of lone pair electrons in the anionic polymer.

摘要： A low cost, sandwich-structured thin film composite (TFC) anion exchange membrane for redox flow batteries, fuel cells, electrolysis, and other electrochemical reaction applications is described. The sandwich-structured TFC anion exchange membrane comprises a microporous substrate membrane, a first hydrophilic ionomeric polymer coating layer on the surface of the microporous substrate layer, a cross-linked protonated polyamine anion exchange polymer coating layer on top of the first hydrophilic ionomeric polymer coating layer, and a second hydrophilic ionomeric polymer protective layer on top of the cross-linked protonated polyamine anion exchange polymer coating layer. Methods of making the TFC anion exchange membrane comprises a microporous substrate membrane and redox flow battery system incorporating the TFC anion exchange membrane comprises a microporous substrate membrane are also described.

摘要： Provided is an apparatus for producing a non-aqueous electrolytic solution capable of easily performing purification treatment by removal of acidic impurities such as hydrogen fluoride contained in a non-aqueous electrolytic solution.
The apparatus for producing a non-aqueous electrolytic solution comprises an ion exchange unit accommodating a weakly basic anion exchange resin through which an alkali metal salt electrolyte-containing solution having the alkali metal salt electrolyte dispersed in an carbonate ester is passed to obtain the non-aqueous electrolytic solution, wherein the weakly basic anion exchange resin has a styrene-based resin as substrate and an amino group as weakly basic anion exchange group.-
