ABSTRACT

Lithium-ion batteries (LIBs) have emerged as a dominant electrochemical energy storage technology, addressing the escalating global demand for efficient and sustainable power solutions. The continuous pursuit of advanced electrode materials is critical to enhancing LIB performance, particularly in terms of energy density, cycle life, and safety. Nanostructured metal oxides have garnered substantial attention as promising anode materials due to their high theoretical capacities, structural versatility, and electrochemical stability. Metal oxides such as as tin oxide (SnO₂), titanium oxide (TiO₂), iron oxides (Fe₂O₃, Fe₃O₄), and vanadium oxide (V₂O₅) exhibit exceptional lithium storage capabilities through conversion and alloying reactions. However, challenges such as significant volume expansion, poor conductivity, and cycling instability hinder their practical implementation. Recent advancements in nanostructuring, doping, and composite formation have significantly mitigated these limitations, enabling improved electrochemical performance. This review comprehensively examines the latest developments in nanostructured metal oxide anodes, focusing on their synthesis, structural modifications, and electrochemical behavior. Key materials such as tin oxide (SnO₂), titanium oxide (TiO₂), iron oxides (Fe₂O₃, Fe₃O₄), and vanadium oxide (V₂O₅), are discussed in detail, highlighting their unique advantages and remaining challenges. Additionally, the role of surface modifications, conductive additives, and hybrid architectures in enhancing performance is explored. The review also provides insights into future research directions, emphasizing scalable synthesis, advanced characterization techniques, and integration into next-generation batteries. By addressing current limitations and optimizing material design, nanostructured metal oxides hold immense potential to revolutionize LIB technology, enabling high-energy-density applications in electric vehicles, grid storage, and portable electronics.
