Revealing Phase Transition in Ni-Rich Cathodes via a Nondestructive Entropymetry Method.

ABSTRACT: With the expanding requirements of recent energy regulations and economic interest in high-performance batteries, the need to improve battery energy density and safety has gained prominence. High-energy-density lithium batteries, employed in next-generation energy storage devices, rely on nickel-rich cathode materials. Since they have extremely high charge/discharge capacity, high operating voltage, prolonged cycle life, and lower cost, nickel-rich cathode materials such as Ni-rich NCM (LiNi_x > 0.8Co_yMn_zO₂) and Ni-rich NCA (LiNi_x > 0.8Co_yAl_zO₂) are of particular interest to researchers. Several in situ characterization methodologies are currently used to understand lit
