Abstract

Use of nickel in a cathode material of the general formula Li (4/3-2x/3-y/3-z/3)NixCoyAlzMn(2/3-x/3-2y/3-2z/3)02 wherein x is greater than 0.06 and equal to or less than 0.4; y is equal to or greater than 0 and equal to or less than 0.4; and z is equal to or greater than 0 and equal to or less than 0.05 for suppressing gas evolution during a charge cycle and/or increasing the charge capacity of the material.
