Layered structural LiNi_xCo_yAl_1−x−yO₂ (NCA, x ≥ 0.8) cathodes have been regarded as one of the most promising cathode candidates for next-generation high-energy density lithium-ion batteries on account of their superior discharge capacity and low cost. Nonetheless, the structural and interfacial instability leads to their poor cyclability and inferior thermal stability, which needs to be urgently addressed prior to their further practical applications. In this review, we give a brief introduction about the degradation mechanism of layered NCA cathodes during charge-discharge processes and summarize proposed performance enhancement strategies, which may contribute to provide important ideas to design and construct integrated layered NCA cathodes for high-energy density lithium-ion batteries.
