Patent number: 12374733Abstract: An efficient and green method for selective extraction of Li from end-of-life secondary LIBs of any capacity and size is provided. Electrochemical driven selective lithium deposition is targeted at the anode/separator interface of the end-of-life LIB. The deposited Li is recovered by processing of an opened or dismantled battery using only distilled or de-ionized water. The process not only enables the recovery of the plated lithium at the anode/separator interface, but also extracts the lithium from the organic salts and/or inorganic salts in the solid electrolyte interface (SEI) layers and from the electrolyte in the separator. In addition, the method partially strips the cyclable Li from the cathode and concentrates it at the anode/separator interface. The concentrated Li is extracted by using aqueous solution such as distilled or de-ionized water followed by recovery of the Li from aqueous solution. After Li recovery from the anode, the method can also enable the recovery of battery-grade graphite.Type: GrantFiled: June 30, 2022Date of Patent: July 29, 2025Assignee: Iowa State University Research Foundation, Inc.Inventors: Cajetan Ikenna Nlebedim, Abhishek Sarkar, Pranav Shrotriya

Patent number: 12358077Abstract: Various embodiments relate to forming particles using undercooled metal particles in response to focused low power laser light. Particle growth can be initiated by utilizing the metastable and liquid nature of the particles, allowing for surface instability promoted by the laser light to induce liquid flow to translate to a neighboring particle. This event can cascade radially leading to accumulation of the liquid metal at the epicenter. The grown solidified particle size can be varied by using different power, exposure time, or working distance. Once the liquid has accumulated into a single region, it eventually solidifies either through homogeneous or heterogeneous nucleation to give a solid particle of larger size than the original. Such a method can be used to print patterns on a surface in four dimensions, where the fourth dimension (4D) is attained through gradient in size of the particles made. Additional systems and methods are disclosed.Type: GrantFiled: February 27, 2023Date of Patent: July 15, 2025Assignee: Iowa State University Research Foundation, Inc.Inventors: Martin Thuo, Peter C. Collins, Andrew Martin

Patent number: 12272471Abstract: The present invention provides fine grain structures for rare earth permanent magnets (REPMs) and their production in a manner to significantly enhance flexural strength and fracture toughness of the magnets with no or little sacrifice in the hard magnetic properties. The tough REPMs can have either homogeneous or heterogeneous refined grain microstructural architectures achieved by introducing a small amount of additive particle materials into the magnet matrix, such as fine-sized, insoluble, chemically stable, and non-reactive with the magnet matrix. These additive materials can act effectively as both heterogeneous nuclei sites and grain growth inhibitors during the heat treatment processes, which in turn resulting in refined grain structures of the REPMs. Alternatively, the fine grain structures were also achieved by using magnet alloy feedstock powders with finer particle sizes.Type: GrantFiled: October 19, 2020Date of Patent: April 8, 2025Assignee: Iowa State University Research Foundation, Inc.Inventors: Baozhi Cui, Jun Cui
