“…First, add the NaOH 5 M solution to pH 4. The solution will then be lowered to pH 2 using the 5 M oxalate acid solution [13]. The result of the copresipitation process is then inhabited, so that natural sedimentation or separation occurs based on the phase between liquid and solid.…”

The co-precipitation approach, along with nickel-rich (NMC622) cathode materials, magnesium, and Fe doping, was used to produce nickel-rich NMC (NMC622) cathode materials from spent nickel catalysts. Both X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were utilized in order to carry out the characterization of the NMC622 materials. The structural study showed that the doped materials had a structure that was equal to that of Li[Ni0,6Mn0,2Co0,2Xy]O2, which has a layered hexagonal structure similar to that of α-NaFeO2. The electrochemical test found that Mg 1 mol% had the highest discharge capacity at 99.61 mAh/g. This was determined by the results of the test. The use of magnesium as a dopant in structurally stable, Ni-rich NMC materials led to an increase in the electrochemical capacity of the Mg-doped NMC. Magnesium exhibited a significant amount of potential as a dopant. It is necessary to do additional research into the functional testing of magnesium as a doping material in order to maximize its use for a longer cycle life and improved thermal stability lithium ion batteries.

“…Recent studies 72 have shown that the partial replacement of Co sites with Cu can effectively reduce the degree of cation mixing and the polarization of the cell during cycling for the purpose of extending the cycle time. Ahmad Jihad et al 125 systematically studied the effect of Cu doping on the structural parameters of NMC622 in terms of lattice parameters, lattice parameter ratio, cation mixing arrangement, grain size, etc. A cross-sectional comparison with Mg, Zn doping was also done, which is shown in Fig.…”

“…According to the result, c/a lattice parameter's value was a direct measurement of the ideal cubic close-packed lattice and was valued at 4.90. This is significant because a structure with a c/a value greater than the stipulated value will become more regular and the lithium-ion exchange will be easier 21,22) . Commercial NMC 811 has c/a of 4.93, while the c/a value of NMC 811 with oxalate and hydroxide precipitating agent can be seen in Table 1.…”

Synthesis of LiNi0.8Mn0.1Co0.1O2 (NMC 811) by coprecipitation method is promising for use. In this study, different precipitation agents were used to comparing the characterization of each cathode. XRD analysis shows that both samples of NMC 811 have a highly layered hexagonal structure. By using FTIR analysis, it was indicated that the two cathodes contain C-H, O-H and C-O groups. Based on SEM analysis, the constituent particles of the cathodes are spherical asymmetrical with the size of the primary particle less than 1 micron and for the secondary particle more than 1 micron. The electrochemical performance showed that NMC-oxalate has a higher specific capacity than NMC-hydroxide. Based on this analysis, oxalate gave better results than hydroxide as a precipitate agent.
