Abstract

Abstract Previous research on NMC811 showed that the higher the Ni content over NMC622, the faster the thermal stability decreased. Therefore, it is necessary to have a type of NMC cathode material that is thermally stable and has better electrochemical performance. In this research, the synthesis of cathode material LiNi0.5Mn0.4Co0.1O2 (NMC541) was carried out using the coprecipitation method to determine the character of the material with variations in calcination temperature of 700, 800 and 850oC. XRD and RAMAN analysis of samples and comparison with references shows that NMC541 material is formed. Observation of surface morphology using SEM on calcified samples at 800oC for 8 hours showed a homogeneous distribution of particles and relatively uniform sizes, as well as the highest conductivity value of 5.099x10− 3 S.cm− 1. Measurements using TEM showed that average grain size of NMC particles was 129.834 nm.
