US Classification:

427 58, 2521821

Abstract:

Compositions and methods of forming battery active materials are provided. A solution of battery active metal cations and reactive anions may be blended with a fuel to yield a precursor mixture usable for synthesizing a battery active material for deposition onto a substrate. The battery active metal cations include lithium, manganese, cobalt, nickel, iron, vanadium, and the like. Reactive anions include nitrate, acetate, citrate, tartrate, maleate, azide, amide, and other lower carboxylates. Suitable fuels, which may be water miscible, may include amino compounds. Alcohols and sugars may be added to adjust carbon content and fuel combustion characteristics. An exothermic reaction is performed to convert the metals into battery active oxides.

US Classification:

2521821, 422198, 422202, 422119

Abstract:

Apparatus and methods of forming a battery-active material are described. An apparatus includes a first processing section that raises the temperature of a precursor material to a reaction threshold temperature, a second processing section that converts the precursor material to a battery-active material, and a third processing section that cools the resulting battery-active material. Each of the processing sections may be a continuous flow tubular component. The first and third processing sections may be metal, and the second processing section may be a refractory material for high temperature service. The battery-active material is collected using a solids collector.

H01M 4/48
C01B 13/34
B01J 19/26

Abstract:

A processing system and method of producing a particulate material from a liquid mixture are provided. The processing system generally includes a system inlet connected to one or more gas lines to deliver one or more gases into the processing system, one or more power jet modules adapted to jet a liquid mixture into one or more streams of droplets and to force the one or more streams of droplets into the processing system, and a reaction chamber adapted to deliver the one or more streams of droplets in the presence of the one or more gases and process the one or more streams of droplets into the particulate material. The method includes delivering one or more gases into a processing system, jetting the liquid mixture into one or more first droplets streams using one or more power jet modules of the processing system and into the processing system, and reacting the one or more first droplets streams delivered from the processing chamber inside a reaction chamber of the processing system in the presence of the one or more gases into the particulate material at a first temperature.

Embodiments of the present invention relate generally to lithium-ion batteries, and more specifically, to batteries having integrated separators and methods of fabricating such batteries. In one embodiment, a lithium-ion battery having an electrode structure is provided. The lithium-ion battery comprises an anode stack, a cathode stack, and a porous electrospun polymer separator comprising a nano-fiber backbone structure. The anode stack comprises an anodic current collector and an anode structure formed over a first surface of the anodic current collector. The cathode stack comprises a cathodic current collector and a cathode structure formed over a first surface of the cathodic current collector. The porous electrospun polymer separator is positioned between the anode structure and the cathode structure.
