Patent number: 11834341Abstract: Provided are processes for the formation of electrochemically active materials such as lithiated transition metal oxides that solve prior issues with throughput and calcination. The processes include forming precursor materials into agglomerates prior to calcination. The use of the agglomerates improves gas flow into and out of the materials thereby improving calcination results, electrochemical properties of the resulting materials, and allows for use of high temperature kilns not previously suitable for such materials thereby lowering production costs.Type: GrantFiled: August 25, 2020Date of Patent: December 5, 2023Assignee: BASF CorporationInventors: William C.

Patent number: 11713494Abstract: Provided are processes for extracting lithium and optionally nickel from a Nickel(II)/Lithium(I) (Ni2+/Li+) solution. The extraction is optionally performed in a series of steps with counterflow of aqueous and organic flows to thereby produce a lithium poor solution. The lithium poor solution may be treated so that remaining Ni in the lithium poor solution may be directly precipitated therefrom in the form of a Ni salt. Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses.Type: GrantFiled: November 4, 2020Date of Patent: August 1, 2023Assignee: BASF CorporationInventors: Jack Bender, William C.

Publication number: 20230114285Abstract: Provided are processes of removing lithium from an electrochemically active composition. The process of removing lithium from an electrochemically active composition may include providing an electrochemically active composition and combining the electrochemically active composition with a strong oxidizer optionally at a pH of 1.5 or greater for a lithium removal time. The electrochemically active composition may include Li, Ni, and O. The electrochemically active composition may optionally have an initial Li/M at % ratio of 0.8 to 1.3. According to some embodiments of the present disclosure, the lithium removal time may be such that a second Li/M at % ratio following the lithium removal time is 0.6 or less, thereby forming a delithiated electrochemically active composition.Type: ApplicationFiled: March 9, 2020Publication date: April 13, 2023Applicant: BASF CorporationInventors: William C.

Patent number: 6447178Abstract: Multiple widths of fluid may be extruded onto portions of material without requiring a complex reconfiguration of the system or replacing the extruding device. In at least one embodiment, various extrusion widths are provided by altering the angle at which materials are guided with respect to the extruding device along a lateral plane with the extruder. In one embodiment, the present invention provides for the manipulation of the position of the extruding device with respect to the material, or alternately, by manipulation of the position of the material with respect to the extruding device. Another embodiment provides a single extruder with multiple applicator heads of different sizes. An additional embodiment provides a single coater head with multiple applicator openings of different sizes. Yet another embodiment provides an extruding device capable of moving laterally over the material to achieve the proper angle of approach.Type: GrantFiled: December 29, 2000Date of Patent: September 10, 2002Assignee: Applied Science Fiction, Inc.Inventors: Michael R. Thering, Joseph B. Gault, John Straigis, Matthew R. Thomas, William C. May
