    Abstract: In a lithium ion battery, one or more chelating agents may be attached to a microporous polymer separator for placement between a negative electrode and a positive electrode or to a polymer binder material used to construct the negative electrode, the positive electrode, or both. The chelating agents may comprise, for example, at least one of a crown ether, a crown ether, a podand, a lariat ether, a calixarene, a calixcrown, or mixtures thereof. The chelating agents can help improve the useful life of the lithium ion battery by complexing with unwanted metal cations that may become present in the battery's electrolyte solution while, at the same time, not significantly interfering with the movement of lithium ions between the negative and positive electrodes.

    Abstract: A method for making a fibrous layer for fuel cell applications includes a step of combining a perfuorocyclobutyl-containing resin with a water soluble carrier resin to form a resinous mixture. The resinous mixture is then shaped to form a shaped resinous mixture. The shaped resinous mixture includes perfuorocyclobutyl-containing structures within the carrier resin. The shaped resinous mixture is contacted (i.e., washed) with water to separate the perfuorocyclobutyl-containing structures from the carrier resin. Optional protogenic groups and then a catalyst are added to the perfuorocyclobutyl-containing structures.

    Abstract: Methods of scavenging acid in a lithium-ion electrochemical cell are provided. An electrolyte solution that contains an acid or is capable of forming the acid is contacted with a polymer comprising a nitrogen-containing acid-trapping moiety selected from the group consisting of: an amine group, a pyridine group, and combinations thereof. The nitrogen-containing acid-trapping moiety scavenges acidic species present in the electrolyte solution by participating in a Lewis acid-base neutralization reaction. The electrolyte solution comprises a lithium salt and one or more solvents and is contained in the electrochemical cell that further comprises a first electrode, a second electrode having an opposite polarity from the first electrode, and a porous separator. Lithium ions can be cycled through the separator and electrolyte solution from the first electrode to the second electrode, where acid generated during the cycling is scavenged by the polymer comprising a nitrogen-containing acid-trapping moiety.

    Abstract: A lithium ion battery includes a positive and a negative electrode, and a nanoporous or microporous polymer separator soaked in electrolyte solution and disposed between the electrodes. At least two different chelating agents are included and selected to complex with: i) two or more different transition metal ions; ii) a transition metal ion in two or more different oxidation states; or iii) both i) and ii). The at least two different selected chelating agents are to complex with transition metal ions in a manner sufficient to not affect movement of lithium ions across the separator during operation of the battery. The chelating agents are: dissolved or dispersed in the electrolyte solution; grafted onto the polymer of the separator; attached to the binder material of the negative and/or positive electrode; disposed within pores of the separator; coated on a surface of the separator; and/or coated on a surface of an electrode.
