An HF-scavenging additive disrupts the autocatalytic H2O/HF cycle for durable Ni-rich layered oxide cathodes

The Nickel-rich layered oxide (NCM) cathodes suffer from rapid capacity degradation, primarily due to trace amounts of water in LiPF₆-based electrolytes trigger LiPF₆ hydrolysis and generate HF. The HF corrodes...
