Compositions with transition metal doping at B-site of lithium nickel oxide (LNO) formulae LiNi1−xMxO2 (where M=Zr, Nb and Mo, 0≤x≤0.80) were synthesised via solid state route. Doping is used over past years to enhance the stability of a “stoichiometric LNO composition. This study reveals the impact of doping Zr+4, Nb5+ and Mo6+ impact on the stability/crystal lattice of lithium nickel oxide (LNO). The focus of investigation was electrochemical properties determined by testing synthesised powders as cathode in half and full coin cells. XRD results revealed that the Zr, Nb and Mo doping resulted in a regular layered structure. The process of doping tailored microstructure, which was revealed smooth via SEM. studies. SEM indicated that the synthesized material has prominent grain growth, with size variation in the grain boundaries due to doping process. The impact of this altered morphology on the electrochemical performance was tested via Arbin work unit at ambient conditions. It was observed that polarization at H2 to H3 phase transition was reduced in the doped compositions even with 1.0% mol. Specific capacity vs. voltage plots reveal 2 mol% doping decreased the discharge capacity. However, the cycling stability over 100 cycles was remarkable with 2 mol % doping. Therefore, we believe that these compositions are very useful in EV device applications, besides cycling for a lithium-ion battery cathode at coin cell level.
