💡 Novelty & Significance:
The novelty lies in an HF-scavenging additive that interrupts the autocatalytic H₂O/HF cycle causing Ni-rich NCM cathode degradation. Its significance is enabling durable, high-capacity Ni-rich layered oxide cathodes by suppressing LiPF₆ hydrolysis and HF corrosion, thereby extending battery cycle life.
