Title: Early transition metal stabilized high capacity cobalt free cathodes for lithium-ion batteries

Abstract

A cathode for a lithium battery includes LiNi_0.5-x/2Mn_0.5-x/2M_xO₂ where M is at least one selected from the group consisting of Mo, Ti, Cr, Zr and V, and x is between 0.005-0.02. The LiNi_0.5-x/2Mn_0.5-x/2M_xO₂ can be coated with Mn₂P₂O₇. The Mn₂P₂O₇ can be 1-3 wt. %, based on the total weight of the LiNi_0.5-x/2Mn_0.5-x/2M_xO₂ and Mn₂P₂O₇. A cathode composition, a lithium battery, and a method of making a lithium battery are also disclosed.
