LiNiO2 (space group: R-3m) doped with Co/Mn/Al meets the demand for high energy density cathode material by offering high operating voltage and high capacity for lithium ion battery application. LiNi1-x-yCoxAlyO2 (LNCA), possessing nano/micro hierarchical architecture, delivers high specific capacity of 200mAh/g with the higher cut-off potential of 4.4V. However, the difficulty in synthesis, voltage fade and poor cycling capabilities due to structural instability and surface degradation pose a serious issue. In order to mitigate the effects of Ni at the electrode-electrolyte interface without ceding the specific energy (>300 Wh/Kg), LiNi1-x-yCoxAlyO2 with reduced concentration of Ni at the surface has been synthesized by optimizing the composition of Ni/Co/Al across the hierarchical structure. The optimum concentration gradient of aluminium maintains the surface structure stability and helps in enhancing the rate capability. The structural and morphological analysis through X-ray Diffraction, scanning electron microscopy and elemental mapping will be presented. The enhancement of electrochemical property due to variation in Al concentration during co-precipitation will be discussed through galvanostatic charge/discharge, cyclic stability, rate capability, cyclic voltammetry and impedance spectroscopy.
