Abstract

O3-type layer-structured Na₀ _. ₈[Ni_1/5Fe_1/5Co_1/5Mn_1/5Ti_1/5]O₂ (denoted as N0.8NFCMTO) has been investigated as a new cathode material for Na-ion batteries. The N0.8NFCMTO cathode delivers an initial discharge capacity of 107 mAhg⁻¹ with excellent cycling stability of over 90% capacity retention after 100 cycles. This material delivers comparable capacity to that of previously reported layered cathode materials with multi-transition metal elements while showing an excellent rate capability and stable long cycle life. Synchrotron-based in situ X-ray diffraction and ex situ X-ray absorption spectroscopy investigations combined with quantitative refinement analysis reveal the reversible structural changes and charge compensation mechanism during sodium extraction/insertion, which is associated with the excellent cycling stability of the N0.8NFCMTO electrode.
