Patent number: 6017654Abstract: Crystalline lithiated transition metal oxide materials having a rhombohedral R-3m crystal structure includes divalent cations selected and added in amounts so that all or a portion of the divalent cations occupy sites in transition metal atom layers within the materials' crystal lattice. The lithiated transition metal oxides are useful as cathode materials in lithium-ion secondary cells. The materials include, but are not limited to, Li.sub.1+x Ni.sub.1-y M.sub.y N.sub.x O.sub.2(1+x) and Li.sub.1 Ni.sub.1-y M.sub.y N.sub.x O.sub.p, wherein M is a transition metal selected from titanium, vanadium, chromium, manganese, iron, cobalt, and aluminum, and N is a group II element selected from magnesium, calcium, strontium, barium, and zinc. The materials provide improved cyclability and high voltage capacity as cathodes in lithium-ion secondary cells. Processes for producing the divalent cation-containing lithium transition metal oxide materials of the invention are also disclosed.Type: GrantFiled: August 4, 1997Date of Patent: January 25, 2000Assignee: Carnegie Mellon UniversityInventors: Prashant Nagesh Kumta, Chun-Chieh Chang, Mandyam Ammanjee Sriram
