Sol-Gel synthesis and crystalline size, dislocation density and microstrain of LiNi0.85Co0.10Mn0.05O2 cathode material for lithium-ion batteries

Abstract

Lithium-ion batteries (LIBs) are essential energy storage solutions for a wide range of applications. The cathode material significantly influences the performance of LIBs. Nickel-cobalt-manganese (NCM) ternary cathode materials have gained prominence due to their potential to offer high capacity, stability and voltage characteristics. In this paper, we focus on the synthesis of NCM cathode material using sol-gel method and its characterization primarily through X-ray diffraction (XRD) analysis. The crystal structure of the synthesized material is investigated using XRD. These XRD patterns are analyzed to estimate particle size and to deduce crystalline size, dislocation density and microstrain. This study helps us better understand how NCM materials are put together, which is important for making high performance lithium-ion batteries. These batteries are used in laptops, electric cars, etc.
