Abstract

, (ii) oxygen release and transition-metal (TM) dissolution that accelerate electrolyte decomposition, and (iii) the dynamic formation, reconstruction, and failure of the cathode-electrolyte interphase (CEI). Recent progress in optimization strategies, including defect engineering (aliovalent doping and vacancy regulation), surface engineering, nano engineering, and electrolyte engineering, is critically evaluated with respect to their ability to suppress structural degradation, limit TM loss, and engineer robust CEIs. Finally, we discuss future directions, emphasizing the need for integrated approaches that combine theory and rational electrolyte design to achieve a durable CEI and crystal stability of the desired inorganic cathode material, in turn, leading to predictive control over long-term electrochemical behavior.
