Description
Synthesis of LiNi_0.8Mn_0.1Co_0.1O_2 (NMC 811) by coprecipitation method is promising for use. In this study, different precipitation agents were used to compar ing 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.
