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.

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.

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.

Abstract: Compositions of polyphosphazene-containing polymers and methods of preparation thereof are provided. The disclosed compositions encompass telechelic functionalized polyphosphazenes and a variety of block and graft polyphosphazene-polystyrene, polyphosphazene-polysiloxane, and polyphosphazene-ROMP of norbornene copolymers. Methods for the preparation of such compositions generally involve generation of a polydichlorophosphazene species, attachment of a function group to the resultant polyphosphazene compound, and coupling the functionalized polyphosphazene with a corresponding organic or inorganic polymers or polymerizing the functionalized polyphosphazene with corresponding organic molecules.

Abstract: A process for the preparation of polyphosphazenes is provided that includes the cationic solution polymerization reaction of a phosphoranimine, using a main group or transition metal halide, or other appropriate halide salt, including a linear phosphazene salt of any chain length, or a preformed non-phosphazene polymer containing a main or transition metal chloride, as an initiator. In a preferred embodiment, triarmed-star polyphosphazenes having the formula N{RN(H)R'.sub.2 P--(N.dbd.PR'.sub.2).sub.n }.sub.3 are prepared via this method. Also, a methods for synthesis of the monomer Cl.sub.3 P.dbd.NSiMe.sub.3 and cyclic trimer N.sub.3 P.sub.3 X.sub.6 from the reactants N(SiR.sub.3).sub.3 and PX.sub.5 are also described.
