Research Progress of MOFs and Their Derivatives as Cathode Materials for Sodium-Ion Batteries

Benefiting from the remarkable advantages of abundant sodium resource reserves and low cost, sodium-ion batteries (SIBs) have emerged as one of the most promising alternative technologies to lithium-ion batteries. However, SIBs still face several technical challenges in practical applications, particularly regarding the energy density and electrochemical performance of cathode materials. Metal-organic frameworks (MOFs), as materials with highly tunable pore structures, excellent specific surface
