Patent number: 11148202Abstract: 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.Type: GrantFiled: December 16, 2016Date of Patent: October 19, 2021Assignee: 6K Inc.Inventors: Kamal Hadidi, Gregory Wrobel, Makhlouf Redjdal

Publication number: 20170373344Abstract: The present disclosure relates to methodologies, systems and apparatus for generating lithium ion battery materials. Starting materials are combined to form a homogeneous precursor solution including lithium, and a droplet maker is used to generate droplets of the precursor solution having controlled size. These droplets are introduced into a microwave generated plasma, where micron or sub-micron scale lithium-containing particles are formed. These lithium-containing particles are collected and formed into a slurry to form lithium ion battery materials.Type: ApplicationFiled: June 23, 2017Publication date: December 28, 2017Inventors: Kamal Hadidi, Gregory Wrobel

Patent number: 9782791Abstract: 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.Type: GrantFiled: April 13, 2016Date of Patent: October 10, 2017Assignees: AMASTAN TECHNOLOGIES LLC, UNIVERSITY OF CONNECTICUTInventors: Makhlouf Redjdal, Kamal Hadidi, Gregory Wrobel, Eric Jordan
