This work uniquely traces the evolution of cathode materials over time, revealing how advancements have shaped modern LIBs. In this paper, we emphasize the innovative approaches used to optimize the porosity, structure and morphology of cathode materials and their intimate correlation with electrochemical properties. Several cathode materials for LIBs including layered transition metal oxides, spinel oxides, olivine oxides are discussed in this review paper along with their advantages and disadvantages.
