Morphology controlled performance of ternary layered oxide cathodes

With the rapid advancement of electric vehicle technologies, ternary layered oxide cathodes in commercial Li-ion batteries have become increasingly promising due to their high energy density and low cost. However, the need for higher energy density and cell stability has posed significant challenges in their development. While various coating and doping strategies have been demonstrated to improve the rate and cycle performance of cathode materials, morphology-focused modifications of these cathodes are sometimes overlooked, despite their impact on electrochemical performance. Herein, this review focuses on the morphological relationship of cathode materials to their electrochemical performance. We summarize the effects of cathode materials morphology on Li-ion diffusion and stability. We also discuss the recent advances in the development of cathode materials with different morphologies. Finally, we present future perspectives for the design of cathode materials with optimized morphologies to promote their commercialization and fundamental research. The effect of morphology-focused modifications is often overlooked despite their impact on battery applications. Here, the morphological relationship of ternary layered oxide cathodes to their electrochemical performance is Reviewed, with guidance suggested for their design and commercialization.
