ABSTRACT

As the most promising secondary energy storage equipment, lithium batteries have been successfully commercialized. Compared with the existing new energy systems, it has the advantages of small size, light material, high voltage, long service life, and low pollution. Anode as the important part of lithium batteries, how its advantages are expanded is the research focus in future. Miniaturization of the negative electrode, nanometer, solved volume expansion problem and slowed down the lithium dendrite problem; Composite materialization provided higher cyclic stability; Alloying of materials made SEI film more stable. This article reviews the research progress on the properties, advantages and disadvantages, and improvement methods of C, Si, and Li-based anode materials.
