Improving Anodes for Lithium Ion Batteries

As energy demands increase for applications such as automotive, military, aerospace, and biomedical, lithium-ion battery capacities are forced to increase in a corresponding manner. For this reason, much research is directed toward the development of improved battery anodes. Carbon nanotubes (CNTs), silicon, tin, and nanocomposites with these metals are the leading candidates for the next generation of lithium-ion battery anodes, leading to capacities 3 to 10 times that of graphite alone. This review looks at some of the studies addressing high capacity lithium-ion battery anodes.
