Synthesis, Characterization, and Evaluation of LiNi0.45Th0.05Mn1.5O4/Polyaniline composite as Cathode Material for Lithium-Ion Batteries

Our study includes a novel process for the synthesis of conductive polyaniline; named self-oxidation polymerization. Spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) and LiNi 0.45 Th 0.05 Mn 1.5 O 4 (LNMO-Th) have been prepared by a sol-gel auto-combustion process. The well crystalline spinel Fd-3 m structures with a high degree of disordering with Th- substituted samples were obtained. The LNMO sample's particle morphology demonstrated a consistent octahedron-like form with a wide range of size distributions. The Th- doped LNMO samples, on the other hand, consisted of bigger, flattened particles with fewer facets and a smaller distribution of particle sizes.
