Recent advances of nanostructured anodes for lithium ion batteries

Abstract:
Due to their high theoretical capacity and energy density, lithium-ion batteries have been widely used in various fields from small electronic devices to electric vehicles. In order to meet the needs of further applications, much research has been put into improving the performance of batteries. Among them, nanotechnology plays a vital role in the preparation of electrodes. Various nanostructures are designed to accommodate changes in the electrode during the charge-discharge cycle. This paper reviews the research progress of four promising cathode materials for the next generation of high energy density lithium batteries. The four materials covered in the paper include graphite, lithium titanate, silicon and iron oxide. The paper first introduces lithium battery and its application and the method to improve the battery performance. The issue then shows the development history of graphite, the most commonly used material, and the recent progress of emerging materials such as lithium titanate, silicon and iron oxide materials and their application to lithium battery performance improvement. And their respective problems and countermeasures. Finally, the problems and research directions of these materials for higher performance of lithium batteries are summarized.
