Summary: The study found that thermal stability of NCM cathode materials is influenced by nickel content and particle structure, with higher nickel content and polycrystal structure showing worse thermal stability. Increasing nickel content leads to a decrease in thermal reaction temperature and activation energy, while polycrystal materials exhibit a slight decrease in activation energy compared to single-crystal materials, with an increase in total enthalpy.
