The present invention provides a nanostructured metal oxide material for use as a component of an electrode in a sodium-ion battery. The material comprises a nanostructured titanium oxide film on a metal foil substrate, which can be produced by depositing or forming a nanostructured titanium dioxide material on the substrate, and then, optionally, charging and discharging the material in an electrochemical cell to improve the capacity and Coulombic efficiency thereof.

Sodium-ion electrochemical cells and batteries

A method of forming an inorganic film on a surface can include depositing a polymer at a layer on a surface, swelling the polymer with a solvent to produce a swollen polymer on the surface, infiltrating the swollen polymer with a precursor, removing the swollen polymer after infiltrating the swollen polymer with the precursor, and forming a porous inorganic film on the surface based on removing the swollen polymer.

Method of forming porous inorganic films via polymer swelling infiltration

The disclosure relates to a method for forming a low refractive index layer on a substrate. The method generally includes (a) applying a block copolymer layer on a substrate, the block copolymer including a polar polymeric block and a non-polar polymeric block; (b) swelling the block copolymer layer with a solvent to increase the block copolymer layer thickness; (c) depositing a metal oxide or metalloid oxide layer on polar polymeric blocks of the block copolymer layer; and (d) removing the block copolymer layer from the substrate, thereby forming a porous metal oxide or metalloid oxide layer on the substrate.

Low refractive index surface layers and related methods

Products and methods for redirecting the pathological biochemical process of accumulation of reduced pyridine nucleotides under deleterious hypoxia conditions toward the reduction of the precursor salt and the biosynthesis of biologically compatible, antioxidant noble metal nanoparticles and the simultaneous restoring of the tissue redox state are provided. The products and methods have application in the treatment of hypoxia and hypoxia-related diseases and disorders. Such products and methods are also useful in organ transplantation and recovery, in screening of anti-hypoxia agents, and in detecting elevated levels of the reducing equivalents of the redox state, for example, NADH, NADPH, GSH, and TrxSH, in cells, tissues, or organs.

Multicomponent inorganic porous materials and methods of making the same

A thermally conductive electrochemical cell comprises a lithium ion-containing liquid electrolyte contacting a cathode and anode. The cathode and anode are in the form of electroactive sheets separated from each other by a membrane that is permeable to the electrolyte. One or more of the cathode and anode comprises two or more layers of carbon nanotubes, one of which layers includes electrochemically active nanoparticles and/or microparticles disposed therein or deposited on the nanotubes thereof. The majority of the carbon nanotubes in each of the layers are oriented generally parallel to the layers. Optionally, one or more of the layers includes an additional carbon material such as graphene, nanoparticulate diamond, microparticulate diamond, and a combination thereof.

Thermally conductive lithium ion electrodes and batteries

The present invention provides a nanostructured metal oxide material for use as a component of an electrode in a lithium-ion or sodium-ion battery. The material comprises a nanostructured titanium oxide or vanadium oxide film on a metal foil substrate, produced by depositing or forming a nanostructured titanium dioxide or vanadium oxide material on the substrate, and then charging and discharging the material in an electrochemical cell from a high voltage in the range of about 2.8 to 3.8 V, to a low voltage in the range of about 0.8 to 1.4 V over a period of about 1/30 of an hour or less. Lithium-ion and sodium-ion electrochemical cells comprising electrodes formed from the nanostructured metal oxide materials, as well as batteries formed from the cells, also are provided.

High capacity electrode materials for batteries and process for their manufacture

A cathode comprises, in its discharged state, a layer of hollow &#x3b3;-FeOnanoparticles disposed between two layers of carbon nanotubes, and preferably including a metallic current collector in contact with one of the layers of carbon nanotubes. Individual particles of the hollow &#x3b3;-FeOnanoparticles comprise a crystalline shell of &#x3b3;-FeOincluding cation vacancies within the crystal structure of the shell (i.e., iron vacancies of anywhere between 3% to 90%, and preferably 44 to 77% of available octahedral iron sites). Sodium ions are intercalated within at least some of the cation vacancies within the crystalline shell of the hollow &#x3b3;-FeOnanoparticles.
