Abstract

A doped spinel comprising the formula:Li1±wMe1vMe2x-vMn2-x-yTiyO4-zFz where, 0≦w<1, 0.3<x≦0.7, 0.3≦v<0.7, x>v, 0.0001≦y≦0.35, and 0.0001≦z≦0.3. Me1 is a metal selected from a group of elements consisting of Cr, Fe, Co, Ni, Cu, and Zn. Me2 is a metal selected from a group of elements consisting of Ni, Fe, Co, Mg, Cr, V, Ru, Mg, Al, Zn, Cu, Cd, Ag, Y, Sc, Ga, In, As, Sb, Pt, Au, and B.
