Publication number: 20230303407Abstract: Disclosed are a ternary cathode material and a preparation method and application thereof. The ternary cathode material has a chemical formula of LiNix CoyMn(1-x-y)MO2, wherein 0.5?x?1, y?0, M is at least one selected from the group of niobium, boron and titanium. In the present disclosure, through the reaction between the niobium compound, the boron compound or the titanium compound with the residual lithium on the surface of the calcinated materials, the micro powder deposits in the defect position of the lithium crystal lattice on the surface of the calcinated material, so that the content of the micro powder can be greatly reduced. Meanwhile part of the surface residual lithium is consumed by the reaction to generate lithium niobate, lithium borate or lithium titanate which is uniformly coated on the surface of the material, thereby obtaining the ternary cathode material with excellent cycle and rate performance.Type: ApplicationFiled: May 27, 2023Publication date: September 28, 2023Inventors: Wenyu Zhao, Dingshan Ruan, Jingjing Liu, Guohan Huang, Yang Xia, Changdong Li

Patent number: 8527223Abstract: In one embodiment, a method for managing an industrial process wherein a processor transforms electronic data into an energy prognosis is provided. An energy related test signal including effective power test data indicative of electrical energy consumed by an energy consuming machine may be received. The energy related test signal may be partitioned into an energy related test sub-signal. Mathematical functions may be applied to the energy related test sub-signal to extract a feature set of data from the energy related test sub-signal. The feature set of data may be transformed with a transformation matrix into a reduced test feature set. The reduced test feature set may be input into a performance assessment algorithm based at least in part upon a reduced training feature set derived from data indicative of electrical energy consumed during healthy operation. A power-based performance index may be generated with the performance assessment algorithm.Type: GrantFiled: September 10, 2010Date of Patent: September 3, 2013Assignee: University of CincinnatiInventors: Mohamed AbuAli, Jay Lee, Wenyu Zhao
