Perspective—Challenges and Benchmarking in Scale-Up of Ni-Rich Cathodes for Sodium-Ion Batteries

Abstract

The recent surge of research in the development of sodium-ion batteries (SIBs) as an alternative to the lithium-ion batteries (LIBs) has shown that the SIBs can reduce the load of the LIBs in certain areas. However, the development of SIBs in the commercial arenas is yet to be tapped. This perspective delineates the importance of Ni-rich cathodes and various strategies to ameliorate the performance of the Ni-rich cathodes in the SIBs. Also, discussed various synthesis routes for the industrial-scale synthesis of Ni-rich materials and tried to elucidate the importance of SC cathodes and the necessity to develop those in SIBs.
