dc.description.abstractSodium‐ion batteries (SIBs) have emerged as a compelling alternative to lithium‐ion batteries (LIBs), exhibiting comparable electrochemical performance while capitalizing on the abundant availability of sodium resources. In SIBs, P2/O3 biphasic cathodes, despite their high energy, require furthur improvements in stability to meet current energy demands. This study introduces a systematic methodology that leverages the meta‐heuristically assisted NSGA‐II algorithm to optimize multi‐element doping in electrode materials, aiming to transcend conventional trial‐and‐error methods and enhance cathode capacity by the synergistic integration of P2 and O3 phases. A comprehensive phase analysis of the meta‐heuristically designed cathode material Na0.76Ni0.20Mn0.42Fe0.30Mg0.04Ti0.015Zr0.025O2 (D‐NFMO) is presented, showcasing its remarkable initial reversible capacity of 175.5 mAh g−1 and exceptional long‐term cyclic stability in sodium cells. The investigation of structural composition and the stabilizing mechanisms is performed through the integration of multiple characterization techniques. Remarkably, the irreversible phase transition of P2→OP4 in D‐NFMO is observed to be dramatically suppressed, leading to a substantial enhancement in cycling stability. The comparison with the pristine cathode (P‐NFMO) offers profound insights into the long‐term electrochemical stability of D‐NFMO, highlighting its potential as a high‐voltage cathode material utilizing abundant earth elements in SIBs. This study opens up new possibilities for future advancements in sodium‐ion battery technology. © 1999-2025 John Wiley & Sons, Inc or related companies.en_AU
