“…To address the lengthy heat treatment times of LLOs, several fast synthesis methods have been proposed, including flame-assisted spray pyrolysis (FASP), microwave synthesis, and carbon-based Joule heating. 29–35 FASP operates as a spray-based technique similar to conventional spray pyrolysis, utilizing flame as a heat source to drive reaction kinetics. 29,36 Microwave heating achieves rapid synthesis by directly absorbing microwave energy into the materials.…”

Cathode materials are the core components of lithium‐ion batteries owing to the determination of the practical voltage and effective energy of the battery system. However, advanced cathodes have faced challenges related to cation migration and cation intermixing. In this review, the study summarizes the structural failure mechanisms due to the cation mixing of advanced cathodes, including Ni‐rich and Li‐rich layered cathodes, spinel, olivine, and disordered rock‐salt materials. This review starts by discussing the structural degradation mechanisms caused by cation intermixing in different cathodes, focusing on the electronic structure, crystal structure, and electrode structure. Furthermore, the optimization strategies for effective inhibition of cation migration and rational utilization of cation mixing are systematically encapsulated. Last but not least, the remaining challenges and proposed perspectives are highlighted for the future development of advanced cathodes. The accurate analysis of cation migration using advanced characterization, precise control of material synthesis, and multi‐dimensional synergistic modification will be the key research areas for cation migration in cathodes. This review provides a comprehensive understanding of cation migration and intermixing in advanced cathodes. The effective inhibition of cation migration and the rational utilization of cation intermixing will emerge as pivotal and controllable factors for the further development of advanced cathodes.
