Abstract
In this study, the synthesis of LiCo1-XSmXOy powders (X = 0.002, 0.004, 0.006, 0.008, and 0.1) by the sol-gel method and the influence of Sm on their structural and morphological properties is reported for the first time. The results of x-ray diffraction (XRD) studies show that LiCoO2 powders synthesized at temperatures up to 700°C present a characteristic hexagonal crystalline phase of the α-NaFeO2 type (space group R-3m), revealing a shift in the (0 0 3) Bragg reflection, which reflects the presence of Sm in the crystalline structure. The morphology was spheroidal and, on average, 122 nm in size. Based on the data obtained, LiCo1-XSmXOy powders (X = 0.002, 0.004, 0.006, 0.008, and 0.1) show promise as a material for use in the cathodes of lithium-ion batteries.

In 2016, Xudong Meng et al [16] increased the charge retention capacity of the LiFePO4/C cathode by 96%, following doping with Sm at 6 mol%; this study revealed that samarium ions increase the conductivity and diffusion of lithium ions, improving their electrochemical performances and, as a result, their charge retention capacity
Summary
The portability of electrical energy is a fundamental part of our daily life, [1] due to the applications of this energy in devices such as cell phones, tablets, laptops, and hybrid, and electric cars. They have been widely used to enhance electrochemical properties and to provide electrical solutions in response to a growing demand for electrical portability [8] [9] [10]
