  • Publication number: 20050170249
    Abstract: A cathode composition for a lithium-ion battery having the formula Li[M1(1-x)Mnx]O2 where 0<x<1 and M1 represents one or more metal elements, with the proviso that M1 is a metal element other than chromium. The composition is in the form of a single phase having an O3 crystal structure that does not undergo a phase transformation to a spinel crystal structure when incorporated in a lithium-ion battery and cycled for 100 full charge-discharge cycles at 30° C. and a final capacity of 130 mAh/g using a discharge current of 30 mA/g.

  • Publication number: 20040020809
    Abstract: A template assembly for locating required mounting holes for door lock has a generally U-shaped flexible end template, support clips pivotably attached to free ends of the end template, and side templates attached to the support clips. The end template has a center hole locating mark, and the side templates have lock cylinder hole locating marks and a strike plate hole locating mark. Alternatively, the side templates are pivotably attachable directly to the free ends of the end template. Alternatively, the template assembly is a one-piece construction, having integrated end template and side templates, the side templates not being pivotable relative the end template.

  • Publication number: 20030108793
    Abstract: A cathode composition for a lithium ion battery that contains lithium having the formula (a) Liy[M1(1−b)Mnb]O2 or (b) Liy[M1(1−b)Mnb]O15+c where 0≦y<1, 0<b<1 and 0<c<0.5 and M1 represents one or more metal elements, with the proviso that for (a) M1 is a metal element other than chromium. The composition is in a form of a single phase having an O3 crystal structure that does not undergo a phase transformation to a spinel crystal structure when incorporated in a lithium-ion battery and cycled for 100 full charge-discharge cycles at 30 C. and a final capacity of 130 mAh/g using a discharge current of 30 mA/g.
