Lithium-ion batteries are the systems of choice, offering high energy density, flexibility, lightness in weight, design and longer lifespan than comparable battery technologies. A brief historical review is given of the development of Li-ion rechargeable batteries, highlighting the ongoing research strategies, and highlighting the challenges regarding synthesis, characterization, electrochemical performance and safety of these systems. This work is primarily focused on development of Li-ion batteries from micro-structured to nanostructured materials and some of the critical issues namely, electrode preparation, synthesis, and electrochemical characterization. The purpose of this review is to act as a reference for future work in this area.
