💡 Novelty & Significance:
This work regulates chemomechanical failure in high-compaction Na4Fe3(PO4)2P2O7 by La doping, which refines grains, strengthens Fe–O bonds, and suppresses microcracks and lattice strain. The optimized cathode delivers 90.4 mAh g–1 at 10 C with 92.2% retention over 5000 cycles, plus wide-temperature pouch-cell stability, offering a practical route to durable, high-energy sodium-ion batteries.
