Abstract
A transition metal based ceramic material having the general formula LiαM1−βTβNxO67, wherein M is a transition metal, T is a dopant metal, and wherein x is greater than 0 and less than or equal to l, δ is 0, or less than or equal to 4; α is less than or equal to 3−x, and β is less than 1 is disclosed. The ceramic material has utility as a cathode material for rechargeable lithium batteries.
