Inorganic particle/polymer composites are described that involve chemical bonding between the elements of the composite. In some embodiments, the composite composition includes a polymer having side groups chemically bonded to inorganic particles. Furthermore, the composite composition can include chemically bonded inorganic particles and ordered copolymers. Various electrical, optical and electro-optical devices can be formed from the composites.

Polymer-inorganic particle composites

Inorganic particle/polymer composites are described that involve chemical bonding between the elements of the composite. In some embodiments, the composite composition includes a polymer having side groups chemically bonded to inorganic particles. Furthermore, the composite composition can include chemically bonded inorganic particles and ordered copolymers. Various electrical optical and electro-optical devices can be formed from the composites.

Nanoscale particles, particle coatings/particle arrays and corresponding consolidated materials are described based on an ability to vary the composition involving a wide range of metal and/or metalloid elements and corresponding compositions. In particular, metalloid oxides and metal-metalloid compositions are described in the form of improved nanoscale particles and coatings formed from the nanoscale particles. Compositions comprising rare earth metals and dopants/additives with rare earth metals are described. Complex compositions with a range of host compositions and dopants/additives can be formed using the approaches described herein. The particle coating can take the form of particle arrays that range from collections of disbursable primary particles to fused networks of primary particles forming channels that reflect the nanoscale of the primary particles. Suitable materials for optical applications are described along with some optical devices of interest.

Improved high rate batteries based on silver vanadium oxide yield improved pulsed performance. In particular, batteries comprise an electrolyte having lithium ions and a cathode comprising silver vanadium oxide. Improved batteries have a pulsed specific energy of at least about 575 mWh/g when pulsed in groups of four-10 second pulses at a current density of 25 mA/cm spaced by 15 seconds between pulses and with 30 minutes between pulse groups down to a discharge voltage of 1.5 volts. In addition, improved batteries can achieve high maximum specific powers, high current densities and no voltage delay in pulsed operation. The batteries are particularly suitable for use in implantable medical devices, such as, defibrillators, pacemakers or combinations thereof. Improved processing approaches are described.

A method for removing HF from a solid electrolyte using alumina is disclosed. The solid electrolyte contains a polymeric matrix, a salt, a solvent, and a toughening agent. The toughening agent may include alumina, silica, zeolite, and metal oxides (e.g., calcium oxide and magnesium oxide), and mixtures thereof. The toughening agent acts as a drying agent to remove excess solvent in the electrolyte. The solid electrolytes have improved mechanical strength and adherence to the anode and cathode.

The present invention is a simple and reliable method for producing lithiated metal oxides such as those useful as cathode materials in lithium ion electrochemical cells. The method is based on the use of an organic solvent that dissolves both lithium sulfide and elemental sulfur without dissolving the metal oxide or the lithiated product. Lithium sulfide and the metal oxide as a powder are refluxed in the organic solvent under an inert atmosphere. The organic solvent dissolves the lithium sulfide and the dissolved sulfide reduces the metal oxide allowing the intercalation of lithium. At the same time the sulfur that results from the oxidation-reduction reaction is carried away by the solvent thereby promoting the reaction and preventing contamination of the product with sulfur.

A cathode for use in an electrochemical cell comprising a lithiated isopolyvanadate or heteropolyvanadate wherein the isopolyvanadate or heteropolyvanate has a cage structure, and an electrochemical battery comprising an alkali metal anode, an ionically conductive electrolyte and a cathode which comprises a lithiated isopolyvanadate or heteropolyvanadate having a cage structure, are described.

This invention relates to a filter and a method of making a filter. The filter is made of randomly orientated fibers made from an interpenetrating network formed from at least two polymers which are substantially water soluble in their salt form and which ionically interact in an aqueous solution to form the interpenetrating network. The filter is made without organic solvents, particularly, volatile organic compounds, and the filter is sufficiently water soluble to biodegrade upon disposal. A desired use of the filter is a cigarette filter.
