Abstract
LiNi0.83Co0.12Mn0.05O2 (NCM83) is considered as a potential cathode material owing to its high energy density and low cost, yet the discharge capacity decays rapidly with the cycles. Dual doping of Mg and Ti is used to improve electrochemical stability. MgxTixMn1-2x(OH)2+x is uniformly coated on the surface of precursor particles by co-precipitation method, and MgxTixMn1-2x diffuses evenly during the sintering process. Mg and Ti successfully enter into the crystal lattice of NCM83. The cells are cycled in 2.8ā4.5 V at 1C for 200 cycles. The specific capacity of NCM83 is 192.1 mAh gā1, and the capacity retention is 61.8% after 200 cycles. The cyclability can be significantly enhanced by dual doping of Mg and Ti, which can maintain 84.3% capacity under the same condition.
