Patent number: 11909041Abstract: This invention provides an environmental friendly method for the production of high capacity cathode materials for use in Li-ion batteries. Traditional methods for producing lithium mixed metal oxide cathode materials typically generate large amounts of effluent which effluent must be treated prior to discharge. The present process uses mixed metals as raw materials, in a wet chemical reaction with an oxidant, in order to make high-quality metal hydroxide precursors which can be used to prepare high-quality cathode materials after lithiation. As a key feature, in the precursor preparation process, the bulk of the aqueous solution used for the wet chemical reaction can be recycled back to the reactor, so that the total process has little or no effluent generated during production of the cathode precursor material.Type: GrantFiled: April 3, 2019Date of Patent: February 20, 2024Assignee: Tesla, Inc.Inventors: Feng Zou, Yang Liu

Patent number: 11909081Abstract: The invention relates to a control device (10) for a fuel cell stack (14), the control device being set up to actuate the fuel cell stack (14) using a predetermined current (IV) and to measure the resulting voltage (U) and to compare this with a reference voltage (UR). The predetermined current (IV) depends on the reference voltage (UR) by means of a sum of at least two exponential functions whose argument in each case contains the reference voltage (UR). The control device (10) is designed to ascertain the reference voltage (UR) by approximately reversing the correlation between the predetermined current and the reference voltage (UR) using an iterative approximation algorithm.Type: GrantFiled: June 15, 2022Date of Patent: February 20, 2024Assignee: Robert Bosch GmbHInventor: Antonius Bader
