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 battery module is provided. The battery module includes a plurality of battery cell assemblies configured to electrically communicate with each other. Each battery cell assembly has an electrode stack enclosed by a case. The electrode stack is positioned in the case to form one or more peripheral spaces between the electrode stack and the case. Support members are positioned adjacent to each of the battery cell assemblies to contact a desired portion of the electrode stack. The support members are configured to focus a compressive force on a desired portion of the electrode stack. The compressive force urges gases formed during operation of the electrode stack into the peripheral spaces within the case.
