Investigation of the correlation between production and magnetic properties and battery performance for rechargeable batteries LiNi0.80Co0.15M0.05O2 (M=Al, Si, Ti)

In this thesis, the samples of LixNi0.80Co0.15M0.05O2 (M = Al, Si, Ti) subjected to 750-degree 24-hour heat treatment were analyzed. LixNi0.8Co0.15Ti0.05O2 (x = 1.03, 1.06, 1.09) According to the XRD data of the samples Li1.09Ni0.8Co0.15Ti0.05O2 other than the impurity, LixNi0.80Co0.15M0.05O2 (M = Si, Ti, x = 1.03, 1.06, 1.09) showed homogenization. In cyclic voltammetry (CV), the best result belongs to Li1.06Ni0.8Co0.15Al0.05O2 phase. The best rechargeable performance is the Li1.06Ni0.8Co0.15Si0.05O2 cathode and the best capacity value from LixNi0.80Co0.15M0.05O2 (M = Al, Si, Ti, x = 1.03, 1.06, 1.09) is 98.7% retention rate of Li1.06Ni0.8Co0.15Ti0.05O2.
