  • CURRENT COLLECTOR COATING FOR LI-ION BATTERY CELLS USING AQUEOUS BINDER
    Publication number: 20120225199
    Abstract: A coating for a current collector for a rechargeable electrochemical cell comprising a water-soluble polymeric material that provides suitable binding and coating characteristics without the need for a thickening agent or any external reagent to control the viscosity of the electrode active mix. Multiple water-based polymeric materials are disclosed. Also disclosed is an electrode active mix that is devoid of any thickening agent or any external reagent to control the viscosity of the electrode active mix.
    Type: Application

  • POLYMER ACIDS AS PH-REDUCING BINDER OR AGENT FOR AQUEOUS LITHIUM-ION BATTERIES
    Publication number: 20120064407
    Abstract: A positive electrode includes positive active material, conductive additive, water soluble polymer, water coated on the current collector. The slurry includes an active material, a water soluble binder, water, and a carboxylic acid-containing polymer sufficient to reduce the pH of the liquid slurry to a level below about 11.8. A method of forming an electrode is also disclosed.

  • POLYMER ACIDS AS BINDER AND PH REDUCING AGENT FOR AQUEOUS LITHIUM-ION CELLS
    Publication number: 20120064229
    Abstract: A positive electrode for an electrochemical cell. The positive electrode includes a current collector that is coated with a slurry comprising a positive active material, a water-soluble polymer which acts as a binder and pH adjuster, a conductive additive and water. The positive active slurry was then coated on to the current collector and dried.
