Synthesis of NMC 111 via urea assisted solid state method

Due to their characteristics of high power, high energy density, high thermal stability and long-life time, NMC metal-based cathode material for lithium ion become one of the most popular material and widely used in the automotive industry. In this study, material of LiNi0.33Mn0.33Co0.33O2 (NMC 111) was synthesized via urea-assisted solid state method. The effect of urea addition of 0, 20, 40, 60 %wt/wt was investigated. Sintering process was carried out at 800°C for 12 hours. The structure of NMC 111 material was analyzed using X-ray Diffraction (XRD). The XRD pattern showed that material of NMC 111 has been successfully synthesized which is indexed well to JCPDS card #20-0781. Cylindrical battery was used to test the electrochemical performance of NMC 111 material. The best of electrochemical performance was obtained by NMC 111 material with 40 %wt addition of urea.
