Meanwhile, the challenges with enabling prolonged cycling (beyond 1000 cycles) may be associated with Fe dissolution and formation of a copper oxide phase. A reversible local and global structural evolution is observed during initial cycles. ![]() Synchrotron X-ray diffraction, spectroscopy, and imaging are applied to elucidate the relationship between chemical/structural evolution and battery performance. ![]() Stable full cell performance is achieved with 84.2% capacity retention after 1000 cycles at a rate of 1 C. A stable electrochemical performance is achieved in Na half cells with 100% capacity retention at a rate of C/10 after 100 cycles (initial capacity of 90 mAh/g), 96% capacity retention at a rate of 1 C after 500 cycles (initial capacity of 70 mAh/g), and 85% capacity retention at a rate of 5 C after 1000 cycles (initial capacity of 55 mAh/g). Herein, we report Na 0.75Co 0.125Cu 0.125Fe 0.125Ni 0.125Mn 0.5O 2 with an intergrowth of ordered P2 and P3 phases, studied by neutron diffraction and Rietveld refinement. P2-type layered oxides are important as cathodes for their reversibility, but their long-term performance in full cells remains a key challenge. Developing stable cathode materials represents a crucial step toward long-life sodium-ion batteries. ![]()
