A method of forming a solid, dense, hermetic lithium-ion electrolyte membrane comprises combing an amorphous, glassy, or low melting temperature solid reactant with a refractory oxide reactant to form a mixture, casting the mixture to form a green body, and sintering the green body to form a solid membrane. The resulting electrolyte membranes can be incorporated into lithium-ion batteries.

An antimicrobial medical device that includes a substrate having a metal surface that is made from a metal or metal alloy that may include stainless steel, cobalt, and titanium. Disposed on the metal surface is a first antimicrobial oxide layer that includes an antimicrobial metal that may include silver, copper, and zinc, and combinations thereof. The atoms of antimicrobial metal in the first antimicrobial oxide layer are of a first concentration. The first antimicrobial oxide layer is positioned in a direction opposite that of the metal surface. The device further includes a second antimicrobial oxide layer that includes an antimicrobial metal that may be silver, copper, and zinc, and combinations thereof. The atoms of the antimicrobial metal present in the second antimicrobial oxide layer are of a second concentration. The first concentration and the second concentration are not equal. Methods for making the antimicrobial medical device are also disclosed.

A method for producing a three-dimensionally shaped object by stacking layers includes forming each layer using a three-dimensional shape composition containing particles, measuring the thickness of the layer, and ejecting onto the layer a liquid binder containing a binding agent capable of binding the particles. For the ejecting, the amount of the liquid binder to be ejected per unit area of the layer when viewed from above is adjusted according to the result of the measuring.

This invention discloses a method of fabricating a reticulated solid electrolyte/separator (RSES) which is suitable both as electrolyte and separator in a solid state battery. The reticulated composite is produced by casting and drying of a slurry which exhibits a high yield stress (greater than 50 dyne/cm2) and comprised of a high MW resin dissolved in a solvent (having solution viscosity of higher than 100 cp at 5% in NMP at room temperature) and dispersed nanoparticles of solid electrolyte of high specific surface areas (i.e. greater than 1 m2/g, preferable greater than 10 m2/g) including but not limited to LLZO, LSP, or LIPON or derivatives thereof. This reticulated solid electrolyte/separator exhibits superior cycling properties and high ionic conductivity, resists lithium dendrite penetration, and maintains a high dimensional stability (less than 10% shrinking) at elevated temperatures (up to 140° C.). In addition, the present disclosure relates to electrochemical cells comprising such a reticulated film composite to act as both electrolyte and separator.
