Abstract Li(Ni x Co y Mn z )O 2 ( + = 1, NCM), as one of the most dominant cathode materials in electric vehicle (EV) batteries, faces challenges poor cycling stability and safety concerns with increase Ni content charge/discharge capacity. Single crystalline NCM (SC‐NCM) have been developed to mitigate these challenges, owing their lower surface areas, fewer grain boundaries, better morphological stability. Here, preparation strategies SC‐NCM are summarized, including continuous high‐temperature sintering (CHTS), molten salt method, pulse (PHTS), controllable growth special orientations or sizes. CHTS produces irregular particles, but is accompanied by Li‐volatilization agglomeration during long‐term sintering. The helps calcination temperature generate well‐defined material, generally causes large capacity loss due Li/H exchange following water rinsing procedure. To address above PHTS strategy has recently proposed, which mitigates Li‐loss through shortened stage avoids further steps. For improving C‐rate performance, crystal specific sizes highly desired, calls for investigation upgrading current large‐scale technology.
