Suppression of partially irreversible phase transition in O'3-Na3Ni2SbO6 cathode for sodium-ion batteries by interlayered structural modulation
文献摘要:
As a promising cathode material for sodium ion batteries,honeycomb-ordered layered Na3Ni2SbO6 still suffers from rapid capacity fading because of partially irreversible phase transition.Herein,a substitution of Na+by Rb+with a larger ionic radius in honeycomb layered Na3-xRbxNi2SbO6 is proposed to modulate the interlayer structure.The results unveil that biphasic transition reversibility of the intermediate P'3 phase is substantially enhanced,and the structure evolution behavior during the charge/discharge pro-cess changes due to the structural modulation,which contributes to a suppression of the unfavorable 01 phase and an alleviation of the lattice distortion.Moreover,Rb substituted samples exhibited an improved Na+(de)intercalation thermodynamics and kinetics.Attributed to the modifications,the sam-ple with optimized Rb content delivers superior cycle stability and rate capacity,demonstrating a feasible strategy for suppressing irreversible phase transition and developing high-performance honeycomb lay-ered materials for sodium ion batteries.
