Nanoengineering of Advanced Carbon Materials for Sodium-Ion Batteries.

Recent research shows that the continuing importance of carbon anode materials plays an important role in the development of sodium-ion batteries. Nevertheless, the practical deployment of sodium-ion batteries still faces many challenges such as mediocre sodium storage capability and short cycle life. Therefore, it is imperative to explore improvement methods to boost their competitiveness. Herein, various nanoengineering strategies, including nanostructure design, defect and heteroatom doping, and nanocomposite optimization, are proposed as reliable and effective approaches to improve electrochemical performances and structural stability of carbon-based anode materials for sodium-ion batteries (SIBs). The feasibility of nanoengineering is highlighted as a promising approach to develop next-generation carbon materials for sodium-ion batteries.
