Research progress in nanotechnology for enhanced silicon-based and iron-based anodes for lithium-ion batteries

Abstract

Recent research has focused on making suitable anode materials for lithium-ion batteries and using nanotechnology to refine composite electrode materials with high reversible capacity and strong stability. However, much work remains to be done to develop these materials into commercially viable solutions. The anode materials must have high reversible capacity, a long lifetime, and the ability to accept and release lithium ions repeatedly. Nano-engineered composite anode materials based on silicon and iron have shown good promise but need improved electrochemical properties and longer effective lifetimes. This paper summarizes the performance characteristics of Si-based and Fe-based anodes and ways to improve their performance through nanoengineering.
