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. Mays, Diana Wong, Xue Liu, Benjamin Reichman, Martin L. Panchula, Gary A. Yacobian

Patent number: 9601755Abstract: Lithiated composite materials and methods of manufacture are provided that are capable of imparting excellent capacity and greatly improved cycle life in lithium-ion secondary cells. By supplementing a high nickel content lithium storage material with a transition metal oxide lithium storage material or a dopant at relatively low levels, the capacity of the high nickel content lithium storage materials is maintained while cycle life is dramatically improved. These characteristics are promoted by methods of producing the materials that intermix unlithiated precursor materials with a lithium source and sintering the materials together in a single sintering reaction. The resulting lithiated composite materials provide for the first time both high capacity and excellent cycle life to predominantly high nickel content electrodes.Type: GrantFiled: March 14, 2013Date of Patent: March 21, 2017Assignee: Ovonic Battery Company, Inc.Inventors: Benjamin Reichman, William Mays, Diana Wong

One click to update buyer in mass on purchaser orders and prepare changes to communicate to supplier
Patent number: 9501801Abstract: A mass change of values of a specified attribute (e.g., buyer identity) of multiple purchase orders can be performed automatically in conjunction with additional automatically performed operations, and all in response to a single user activation of a button control, without requiring any further human intervention. The additional operations can include the creation of change orders for each changed purchase order; the logging of each change made to each purchase order in an audit history; the requesting of change approvals for purchase orders; and the preparation of the created change orders for communication to suppliers to whom the changed purchase orders pertain. Thus, each supplier can made aware via an automated process that he is now dealing with a different entity than before.Type: GrantFiled: September 26, 2013Date of Patent: November 22, 2016Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Elaine Diana Wong, Thomas Keith Workman -
