This chapter introduces readers to a new kind of hierarchically
nanostructured electrode materials for lithium-ion batteries. In
this chapter, readers will learn the basic working principle of a
typical lithium-ion battery as well as each component in the battery,
and the materials used for fabricating the battery electrodes. In
addition, it discusses both advantages and disadvantages in the use
of nanomaterials and makes a comparison between nanomaterials
and their micron-scale counterparts. Thus, readers understand
the necessities to employ new materials, such as hierarchically
nanostructured materials for the purpose of eliminating the flaws of
nanomaterials to the greatest extent while retaining their inherent
merits. Various examples of such structures, including sphere-
like and flower-like nano/micro hierarchical structures as well as
