Navigating thermal stability intricacies of high-nickel cathodes for high-energy lithium batteries
Nature Energy, Published online: 07 March 2025; doi:10.1038/s41560-025-01731-xHigh-nickel oxide cathodes are important for automotive lithium batteries but face thermal instability challenges. This study analyses a range of materials, quantifying how the cathode chemistry, nickel content, morphology and state of charge dictate the stability, and proposes a thermal stability index.
