  • Early transition metal stabilized high capacity cobalt free cathodes for lithium-ion batteries
    Patent number: 11394020
    Abstract: A cathode for a lithium battery includes LiNi0.5-x/2Mn0.5-x/2MxO2 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 LiNi0.5-x/2Mn0.5-x/2MxO2 can be coated with Mn2P2O7. The Mn2P2O7 can be 1-3 wt. %, based on the total weight of the LiNi0.5-x/2Mn0.5-x/2MxO2 and Mn2P2O7. A cathode composition, a lithium battery, and a method of making a lithium battery are also disclosed.
