This review discusses recent advancements in the synthesis and characterization of nanostructured cathode materials for lithium-ion batteries, aiming to enhance energy density, rate capability, and cycling stability. Nanostructured materials, such as lithium transition metal oxides, vanadium oxides, manganese oxides, and lithium phosphates, offer significant improvements due to their large surface area, short diffusion paths, and volume change freedom. The review highlights the unique properties and challenges of each type of nanostructured material, including their synthesis methods, electrochemical performance, and potential applications. For instance, lithium transition metal oxides like LiCoO₂, LiNiO₂, and LiMn₂O₄ have been extensively studied for their high energy density, but they face issues with toxicity and rate capability. Nanostructured forms of these materials can mitigate these problems by improving diffusion kinetics and stability. Vanadium oxides, known for their low cost and high energy densities, have been explored for their potential in lithium-ion batteries, with studies focusing on their nanoroll, nanotube, and nanocable structures. Manganese oxides, both amorphous and crystalline, have also shown promise as cathode materials, particularly in their ability to act as both cathode and anode materials. The review concludes by discussing the use of nanosized coatings to enhance the stability and performance of lithium transition metal oxides, emphasizing the importance of tailoring the size and morphology of these coatings to optimize their electrochemical properties.This review discusses recent advancements in the synthesis and characterization of nanostructured cathode materials for lithium-ion batteries, aiming to enhance energy density, rate capability, and cycling stability.
