Investigation of the Synergetic Effects of GO and Zn on the Electrochemical Properties of Li[Li₀.₂₀Mn₀.₅₄Ni₀.₁₃Co₀.₁₃]O₂ Cathode Material

This study explores the impact of incorporating graphene oxide (GO) and zinc (Zn) on the electrochemical performance of the Li[Li۰.۲۰Mn۰.۵۴Ni۰.۱۳Co۰.۱۳]O۲ cathode material, a candidate for high-performance lithium-ion batteries. Through the sol-gel and hydrothermal synthesis methods, composite structures were achieved by combining the base material with GO and introducing Zn as a dopant. Comprehensive electrochemical assessments, including cyclic voltammetry and electrochemical impedance spectroscopy, were conducted to analyze how these modifications affect charge transfer, capacity, and ionic conductivity. The results revealed that the GO addition enhances conductivity and stability, while Zn doping significantly reduces polarization and improves lithium-ion transport. Together, GO and Zn achieve synergistic effects, resulting in improved cycling stability and higher capacity, underscoring their potential to optimize the performance of Li-rich layered oxide cathodes.
