"Sodium Difluoro(oxalato)borate Additive-Induced Robust SEI and CEI Lay" by Xiaohao Liu, Jiahua Zhao et al.
Sodium-ion batteries (SIBs) are a promising candidate for large-scale energy storage due to the low cost and abundant sodium resources. However, the formation of sodium dendrites on the surface of hard carbon (HC) anodes is the most intractable challenge for full cells during charging, leading to severe performance degradation and safety hazards. Here, a robust additive-induced borate and fluoride-rich interphase is constructed by introducing sodium difluoro(oxalato)borate (NaDFOB) as additive i...
