20100068605 | REJUVENATION AND REUSE OF DEGRADED LITHIUM ION BATTERY CELLS - One embodiment includes a method for rejuvenating failed or degraded pouch-type lithium-ions batteries. | 03-18-2010 |
20100124691 | METHOD AND APPARATUS FOR REJUVENATION OF DEGRADED POUCH-TYPE LITHIUM ION BATTERY CELLS - One embodiment includes a method including use of a manifold connected to one or more pouches for rejuvenating failed or degraded pouch-type lithium-ions batteries. | 05-20-2010 |
20110151333 | LITHIUM ION BATTERY - 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 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. | 06-23-2011 |
20110165459 | LITHIUM ION BATTERY - 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 podand, a lariat ether, a calixarene, a calixcrown, or mixtures thereof.

20120244390 | SELF HEALING LITHIUM-ION BATTERY NEGATIVE ELECTRODES, PRODUCT INCLUDING SAME, AND METHODS OF MAKING AND USING SAME - One embodiment includes a lithium-ion battery negative electrode including one or more low-melting point alloys that react with lithium. | 09-27-2012 |
20120244418 | LIQUID-METAL NEGATIVE ELECTRODE FOR LITHIUM-ION BATTERIES - One embodiment includes a liquid-metal alloy negative electrode for a lithium-ion battery. | 09-27-2012 |
20120301790 | LITHIUM ION SECONDARY BATTERY ELECTRODE AND METHOD OF FORMING SAME - A method of forming an electrode of a lithium ion secondary battery includes combining a binder and active particles to form a mixture, coating a surface with the mixture to form a coated article, translating the article along a first plane, cutting a first plurality of carbon fibers, each having a first average length, to form a second plurality of carbon fibers, each having a longitudinal axis and a second average length that is shorter than the first average length, inserting the second plurality of fibers into the mixture layer so that the longitudinal axis of each of at least a portion of the second plurality of fibers is not parallel to the first plane to form a preform, wherein the second plurality of fibers forms a truss structure disposed in three dimensions within the mixture layer, and heating the preform to form the electrode. An electrode is also disclosed. | 11-29-2012 |
20140272514 | BATTERY MODULE FOR MITIGATING GAS ACCUMULATION AND METHODS THEREOF - 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. | 09-18-2014 |
