However, beyond simply altering the sodium content, rational control of the O3\/P2 ratio in these materials has proven particularly challenging despite being crucial for the realization of high-performance electrode materials. Here, using abundant elements, we manipulate the O3\/P2 ratio using the average ionic radius of the transition metal layer and different synthesis conditions. These methods allow deterministic control over the O3\/P2 ratio, even for constant Na contents. In addition, tuning the O3\/P2 ratio yields high-performing materials with different performance characteristics, with a P2-rich material achieving high rate capabilities and excellent cycling stability (92% retention, 50 cycles), while an O3-rich material displayed an energy density up to 430 Wh kg \u22121 , (85%, 50 cycles). These insights will help guide the rational design of future high-performance materials for sodium-ion batteries.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s43246-023-00337-8 Authors: Philip A.
