Disclosed herein are embodiments of systems and methods for recycling used solid feedstocks containing lithium powders for use in lithium-ion batteries. The used solid feedstocks may be Lithium Nickel Manganese Cobalt Oxide (NMC) materials. In some embodiments, the used solid feedstock can undergo a microwave plasma process to produce a newly usable, lithium supplemented solid precursor with augmented chemistries and physical properties.

Methods and systems for reclamation of Li-ion cathode materials using microwave plasma processing

Methodologies, systems, and devices are provided for producing metal spheroidal powder products. By utilizing a microwave plasma, control over spheriodization and resulting microstructure can be tailored to meet desired demands.

Spheroidal titanium metallic powders with custom microstructures

Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.

Spheroidal dehydrogenated metals and metal alloy particles

Methods are disclosed for producing core-shell particles having a uniform size using a microwave plasma process. More particularly, methods of the present technology are used to manufacture core-shell particles having a core at least partially surrounded by a shell. The core and shell of the core-shell particles are chemically distinct. Methods of the present technology occur within a plasma chamber of a microwave plasma reactor and a microwave formed plasma is utilized to vaporize core precursor material.

Method of manufacturing core-shell particles by a microwave plasma process

Disclosed herein are embodiments of doped and undoped spherical or spheroidal lithium lanthanum zirconium oxide (LLZO) powder products, and methods of production using microwave plasma processing, which can be incorporated into solid state lithium ion batteries. Advantageously, embodiments of the disclosed LLZO powder display a high quality, high purity stoichiometry, small particle size, narrow size distribution, spherical morphology, and customizable crystalline structure.

Lithium lanthanum zirconium oxide (LLZO) powder

Systems, methods, and devices are disclosed for producing quantum particles (e.g., quantum dots) having a uniform size by vaporization of molten precursor droplets. More particularly, the present technology produces quantum dots by melting or liquefying solid and substantially pure precursor materials followed by production of uniformly sized droplets of molten precursor by use of a droplet maker into a microwave generated plasma torch.

Apparatus and method for the production of quantum particles

Systems, methods, and devices are disclosed for producing substantially uniform droplets. The system includes a fluid reservoir vessel defining a fluid reservoir, a separation membrane at one end of the fluid reservoir, at least one capillary channel at an opposite end of the fluid reservoir, a solution dispenser, and a piezo actuator in contact with a separation membrane. The separation membrane has a thickness greater than about 0.2 mm, and the solution dispenser maintains the fluid reservoir filled with fluid such that the fluid simultaneously contacts the separation membrane and the capillary channel. The solution dispenser maintains the fluid reservoir under pressure to create a fluid stream exiting the capillary. The piezo actuator is in contact with the separation membrane on a side opposite that in contact with the fluid, and the piezo actuator transfers a pressure wave through the fluid in the fluid reservoir to break up the fluid stream into uniform droplets.
