A novel border-rich Prussian blue synthetized by inhibitor control as cathode for sodium ion batteries

Electrolyte Additives for Room‐Temperature, Sodium‐Based, Rechargeable Batteries

“…Following thorough optimization of the electrolytes, 1 m NaPF 6 –EC/PC/FEC (49:49:2) turned out to be the best performing electrolyte composition . This is indeed because the addition of FEC favors the formation of conductive and mechanically stable CEI layers on the positive electrode, thereby resulting in an improvement in both CE and cycling life for the Na–PB‐based cells (Figure ) …”

Recent research progresses in ether‐ and ester‐based electrolytes for sodium‐ion batteries

“…Nowadays, one of the frontiers of research is mainly focused on the development of film‐formation additives, which can be used for interfacial chemistry modification to enhance the cycling performance and, most importantly, the safety of SIBs. To date, fluoroethylene carbonate (FEC) has been one of the most successful film‐forming additives, not merely for LIBs, but for SIBs as well . Komaba et al, screened electrolyte additives for HC anodes and NaNi 1/2 Mn 1/2 O 2 cathodes, finding that FEC is the most efficient electrolyte additive to improve the cycling performance of SIBs (Figure A,B).…”

[61][62][63] Komaba et al, 61 screened electrolyte additives for HC anodes and NaNi 1/2 Mn 1/2 O 2 cathodes, finding that FEC is the most efficient electrolyte additive to improve the cycling performance of SIBs ( Figure 4A,B). In contrast, other well-known and effective additives for LIBs, such as ethylene sulfite, vinylene carbonate, and difluoroethylene carbonate (DFEC), unfortunately, were found to be ineffective in SIBs (Figure 4C).…”
