Rechargeable sodium-ion batteries (SIBs) are regarded as a promising candidate for the next generation energy storage devices owing to the enormous supply of sodium. In particular, layered sodium oxide NaxMO2 (M is a transition metal) with reversible deintercalation and intercalation has aroused interest over recent years. A novel layered composites material with P2+O3 structural integration show unexpected ehancement of electrochemical performance. However, the structure information of this class of materials, including the composition of phase and structure evolution, needs to be investigated in detail. Here we plan to measure 4 Na0.8Ni0.22Li0.12Ti0.66-xMnxO2 samples (x=0, 0.22, 0.44, 0.66) at room temperature and 4 NaxNiyMnzTi1-y-zO2 samples at different temperature (3K, 300K, 700K, and 1000K) by neutron powder diffraction, and to investigate the structure evolution of this intergrowth.
