    摘要: An aggregate composition and process for making the aggregate composition. The aggregate composition includes an insoluble rare earth-containing compound and a polymer binder. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. A suitable insoluble cerium-containing compound can be derived from cerium carbonate or a cerium salt. In a specific embodiment, the aggregate composition consists essentially of one or more cerium oxides, the polymer binder and optionally a flow aid. A process for making the composition includes mixing the insoluble rare earth-containing compound with a polymer binder to form a mixture, and subjecting the mixture to mechanical, chemical and/or thermal treatment to adhere the rare earth compound to the polymer binder. The aggregate composition can be used in a variety of fluid treatment applications to remove one or more chemical and biological contaminants in a fluid.

    摘要: The present invention includes lithium cobalt oxides having hexagonal layered crystal structures and methods of making same. The lithium cobalt oxides of the invention have the formula LiwCo1−xAxO2+y wherein 0.96≦w≦1.05, 0≦x≦0.05, −0.02≦y≦0.02 and A is one or more dopants. The lithium cobalt oxides of the invention preferably have a position within the principal component space defined by the relationship axi+byi≦c, wherein xi={right arrow over (S)}i&Circlesolid;{right arrow over (P)}c1; yi={right arrow over (S)}i&Circlesolid;{right arrow over (P)}c2; the vector {right arrow over (S)}i is the x-ray spectrum for the LiwCo1−xAxO2+y compound; the vectors {right arrow over (P)}c1 and {right arrow over (P)}c2 defining the principal component space are determined by measuring the x-ray powder diffraction values {right arrow over (S)}i between 15° and 120° using a 0.02° step size and CuK&agr; rays for a large sample set of lithium cobalt oxides and using the regression of {right arrow over (S)}i of the sample set against the capacity fade after 50 cycles of a lithium coin cell that includes a lithium negative electrode and the lithium cobalt oxide as the positive electrode material and that is cycled between 3.0 and 4.3V at a constant current of C/3 during both charge and discharge cycles; and the values a, b and c are determined by using only the xi and yi values for LiwCo1−xAxO2+y compounds in the sample set that have a capacity fade after 50 cycles of less than or equal to 15%.
