Nanoparticles Engineering for Lithium‐Ion Batteries

Abstract

Lithium‐ion batteries (LIBs) have been extensively investigated due to the ever‐increasing demand for new electrode materials for electric vehicles (EVs) and clean energy storage. A wide variety of nano/microstructured LIBs electrode materials are hitherto created via self‐assembly, ranging from 0D nanospheres; 1D nanorods, nanowires, or nanobelts; and 2D nanofilms to 3D nanorod array films. Nanoparticles can be utilized to build up integrated architectures. Understanding of nanoparticles’ self‐assembly may provide information about their organization into large aggregates through low‐cost, high‐efficiency, and large‐scale synthesis. Here, the focus is on the recent advances in preparing hierarchically nano/microstructured electrode materials via self‐assembly. The hierarchical electrode materials are assembled from single component, binary to multicomponent building blocks via different driving forces including diverse chemical bonds and non‐covalent interactions. It is expected that nanoparticle engineering by high‐efficient self‐assembly process will impact the development of high‐performance electrode materials and high‐performance LIBs or other rechargeable batteries.
