Title: Nano-sized structured layered positive electrode materials to enable high energy density and high rate capability lithium batteries

Abstract

Nano-sized structured dense and spherical layered positive active materials provide high energy density and high rate capability electrodes in lithium-ion batteries. Such materials are spherical second particles made from agglomerated primary particles that are Li.sub.1+.alpha.(Ni.sub.xCo.sub.yMn.sub.z).sub.1-tM.sub.tO.sub.2-dR.sub.d- , where M is selected from can be Al, Mg, Fe, Cu, Zn, Cr, Ag, Ca, Na, K, In, Ga, Ge, V, Mo, Nb, Si, Ti, Zr, or a mixture of any two or more thereof, R is selected from F, Cl, Br, I, H, S, N, or a mixture of any two or more thereof, and 0.ltoreq..alpha..ltoreq.0.50; 0<x.ltoreq.1; 0.ltoreq.y.ltoreq.1; 0<z.ltoreq.1; 0.ltoreq.t.ltoreq.1; and 0.ltoreq.d.ltoreq.0.5. Methods of preparing such materials and their use in electrochemical devices are also described.
