Understanding the Energy Storage Principles of Nanomaterials in Lithium-Ion Battery

Abstract

Nanostructured materials offering advantageous physicochemical properties over the bulk have received enormous interest in energy storage and conversion. The nanomaterials have greatly enhanced the performance of electrochemical cells through the optimized surface, size and dimension, as well as the synergy between the bulk and interface. The booming nanotechnologies provide effective tools in fabricating nanomaterials at atomic or molecular scale with specific morphological and electronic structure. In this chapter, we will focus on the nanostructured materials used in lithium-ion batteries and supercapacitors by introducing the progress of nanomethodologies and popular nanostructured materials in each application. Novel and powerful functional nanomaterials are being rapidly developed to advance the technologies of energy storage and conversion. The understanding of the processing mechanisms in material synthesis and the relationship between the material structure and resulted electrochemistry is critical for the rational synthesis of nanomaterials. Unambiguous knowledge in the electrochemistry of nanomaterials benefts the improvement of the synthetic protocols of materials and the advancement of eletrochemical energy-storage devices.
