💡 Novelty & Significance:
The novelty lies in coherently intergrowing a perovskite Ca2MnO4 phase into layered NaNi1/3Fe1/3Mn1/3O2, creating an intrinsic strain-tolerant architecture. This perovskite buffer constrains lattice strain during rapid Na+ deintercalation, stabilizing structural evolution. It offers a structure-level strategy beyond compositional or surface tuning, enabling high-rate, long-life sodium-ion batteries.
