Lithium ion battery is essential for electric vehicles development. One of the most promising cathode materials for Li-ion battery is LiNi0.8Mn0.1Co0.1O2 (NMC 811) due to its high energy density. However, it caused a low rate capability and obvious capacity degradation at high potential cycle. These limits its practical application. One of the potential solutions to overcome that problem is by doping. In order to modify the crystal structure for performance improvement, the cathode material can be doped by rare earth elements (REE). Besides, Indonesia has one of the biggest deposits for REE. The most promising REE is cerium, because it has been much widely used for catalyst and addition in many fields. In this research, NMC 811 is doped by Cerium Nitrate (Ce (NO3)3) using co-precipitation method for 5 hours followed by heat treatment. The product was characterized by XRD (X-Ray Diffraction), in order to understand its structural behavior. The cerium has reduced the cobalt composition by 0.02, 0.03, and 0.04 mol. The result shows that the doping did not affect the layered oxide structure of NMC 811, except the increasing of Ce-doped crystallite size to 1275.6 Å rather than pristine. [ABSTRACT FROM AUTHOR] |
