Abstract The robust respective formations of a solid electrolyte interphase (SEI) and pillar at the surfaces hard carbon O3-type positive electrodes are consequences integrating LiPF 6 salt into sodium-ion battery that considerably strengthens both interfaces negative electrodes. improvement cycle performances due to formation highly passivating SEI on electrode is induced by alternated solvation structure following addition Li salt, which inhibits electron leakage from further decomposition. with incorporated less soluble than Na-based SEI, passivation ability initially formed can thus be well preserved. Conversely, gas evolution caused oxygen release reduced marginal surface intercalation ions O3-positive electrode. Additionally, LiF layer forms O3 diminishes additional deterioration after formation. Compared fluoroethylene carbonate additive typically applied, simultaneously strengthened interface yields major improvements in capacity retention.

Abstract Sodium‐ion batteries (SIBs) have emerged as a promising alternative for large‐scale energy storage due to the abundance of sodium resources. Among cathode materials, layered oxides shown exceptional potential, yet their practical application is hindered by structural instability during electrochemical cycling. In this study, challenge addressed introducing novel strategy Cu and F dual doping into octahedral ligand field oxygen‐activated P2‐type Na 0.67 Ni 0.33 Mn O 2 oxides. Through comprehensive suite advanced characterization techniques, unprecedented insights modulation oxygen redox activity are uncovered. Ex situ X‐ray photoelectron spectroscopy Raman reveal enhanced reversibility stability in chemical bonding, while diffraction analysis indicates suppression detrimental phase transitions, ensuring stable unobstructed + diffusion pathway. Density functional theory calculations further elucidate that Cu‐F co‐doping reduces overlap between t g orbitals 2p orbitals, thereby inhibiting activity. Remarkably, co‐doped material exhibits significantly improved capacity retention rate performance. This work not only advances fundamental understanding engineering but also provides transformative approach designing high‐performance materials SIBs, paving way widespread adoption systems.
