Transformative Effect of Li Salt for Proactively Mitigating Interfacial Side Reactions in Sodium-Ion Batteries

Highlights LiPF6 integration into sodium-ion battery electrolytes strengthens solid electrolyte interphase (SEI) film and stabilizes O3 electrode surfaces, enhancing cycleability with 92.7% at 400 cycles. Li-based SEI exhibits reduced solubility, effectively suppressing sodium-ion and electron leaka...
