The growing dependence on electric mobility, portable electronics, and renewable-energy storage has intensified the need for lithium-ion batteries that can deliver greater energy density, faster charging, and longer service life. Conventional graphite anodes, although well established, are constrained by their limited lithium-storage capacity and slower ion mobility, making them inadequate for the performance demands of next-generation batteries. Recent advances in nanotechnology have enabled researchers to design anode materials with highly controlled structures that significantly improve reaction kinetics, mechanical stability, and long-term cycling behavior. This review discusses progress across a wide range of nanostructured anode systems, including carbon nanomaterials, silicon and silica designs, tin-based compounds, transition-metal oxides, MXenes, MOF-derived materials, and emerging phosphorus-based and other advanced nanostructured anode materials. Their enhanced performance arises from features such as short diffusion pathways, high surface area, and architectures that buffer volume changes during repeated lithiation and delithiation. Although these materials show tremendous promise, several challenges remain before they can be widely adopted, especially in maintaining interface stability, reducing irreversible capacity loss, and achieving scalable, cost-effective production. Continued efforts in material engineering, modelling, and environmentally conscious fabrication will be essential to translate these advances into commercially viable lithium-ion batteries capable of meeting future energy-storage demands.
