An improved structure of nano-scaled and nanostructured Si particles is provided for use as anode material for lithium ion batteries. The Si particles are prepared as a composite coated with MgO and metallurgically bonded over a conductive refractory valve metal support structure.

Nano-scale/nanostructured Si coating on valve metal substrate for lib anodes

An electrically active electrode material for use with a lithium ion cell, a lithium ion cell, and a method for forming the electrochemically active material electrode material are described. The electrode material is in the form of a sheet or mat formed of a valve metal material formed of filaments of a valve metal not larger than about 10 microns in cross section, and coated with an electrochemically active material such as silicon nanoparticles.

Medical implantable lead and manufacture thereof

The method for forming a 3-D metal object by 3-D printing or injection molding comprising providing as a feed material metal particles formed by establishing multiple metal components in a primary billet of a ductile material, working the primary billet through a series of reduction steps to form the components into elongated elements, leaching the ductile material from the elongated elements and reducing the length to short uniform lengths.

System and method for fabrication of 3-D parts

A process of forming porous electrolytic electrode in which alternating layers of a valve metal and a ductile metal are combined to form a billet, and the billet mechanically reduced by exclusion and drawing prior to etching. One or more slots are formed in the billet prior to the mechanical reducing, and filled with the ductile metal.

Methods for fabrication of improved electrolytic capacitor anode

A process for making a valve metal material useful for forming electrolytic devices comprising the steps of: establishing multiple tantalum or niobium components in a billet of a ductile material; working the billet to a series of reduction steps to form said tantalum or niobium components into elongated elements; cutting the resulting elongated elements and leaching the ductile metal from the elements; washing and mixing the cut elements; and forming the cut elements into a sheet. The resulting sheet may be formed into anodes and cathodes and assembled to form a wet electrolytic capacitor.

Wet electrolytic capacitor and method for fabricating of improved electrolytic capacitor cathode

A superconducting material useful for forming electrolytic devices is made by establishing multiple niobium or tantalum components in a primary billet of a ductile material; working the primary billet through a series of reduction steps to form the niobium or tantalum components into elongated elements; cutting and restacking the resulting elongated elements with a porous confining layer to form a secondary billet, working the secondary billet through a series of reduction steps including twisting and final rolling to thin ribbon cross-sections with greater than 5:1 Aspect Ratios; cutting the resulting elongated billet into sections; and leaching the core and sheath at least in part.

Production of electrolytic capacitors and superconductors

Process for producing superconductor

A niobium-based superconductor is manufactured by establishing multiple niobium components in a billet of a ductile metal, working the composite billet through a series of reduction steps to form the niobium components into elongated elements, each niobium element having a thickness on the order of 1 to 25 microns, surrounding the billet prior to the last reduction step with a porous confining layer of an acid resistant metal, immersing the confined billet in an acid or a high temperature liquid metal to remove the ductile metal from between the niobium elements while the niobium elements remain confined by said porous layer, exposing the confined mass of niobium elements to a material capable of reacting with Nb to form a superconductor.
