摘要： An ion conducting polymer comprising a modified poly(phenylene oxide) is described. In an exemplary modified polymer, a portion of the monomeric units are attached to a sulfonate-substituted arylamino moiety, such as a monovalent derivative of phenoxy aniline trisulfonate (BOATS), to form a monomeric unit with a charged side chain. Ion conducting polymers can also be prepared with polyether-containing side chains. The ion conducting polymer can be used to prepare ion exchange membranes which can be used in a variety of applications, such as in non-aqueous redox flow batteries and related energy storage systems.

摘要： The instant disclosure or invention is preferably directed to a polyamide-imide coated membrane, separator membrane, or separator for a lithium battery such as a high energy or high voltage rechargeable lithium battery and the corresponding battery. The separator preferably includes a porous or microporous polyamide-imide coating or layer on at least one side of a polymeric microporous layer, membrane or film. The polyamide-imide coating or layer may include other polymers, additives, fillers, or the like. The polyamide-imide coating may be adapted, for example, to provide oxidation resistance, to block dendrite growth, to add dimensional and/or mechanical stability, to reduce shrinkage, to add high temperature performance (HTMI function), to prevent electronic shorting at temperatures above 200 deg C., and/or the like. The microporous polymeric base layer may be adapted, at least, to hold liquid, gel, or polymer electrolyte, to conduct ions, and/or to block ionic flow between the anode and the cathode in the event of thermal runaway (shutdown function). The polyamide-imide coated separator may be adapted, for example, to keep the electrodes apart at high temperatures, to provide oxidation resistance, to block dendrite growth, to add dimensional stability, to reduce shrinkage, to add high temperature performance (HTMI function), to prevent electronic shorting at temperatures above 200 deg C., to increase puncture strength, and/or to block ionic flow between the anode and the cathode in the event of thermal runaway (shutdown function). Although secondary lithium battery usage may be preferred, the instant polyamide-imide coated membrane may be used in a battery, cell, primary battery, capacitor, fuel cell, textile, filter, and/or composite, and/or as a layer or component in other applications, devices, and/or the like.
