The 6th International Conference on Nanomaterials and Advanced Energy Storage Systems. Institute of Batteries LLP, Nazarbayev University, and PI “National Laboratory Astana”. p18.http://nur.nu.edu.kz/handle/123456789/3424These We developed Na3V(PO3)3N as a novel 4V-class and zero-strain cathode material for Na-ion batteries. Through the combined studies using neutron and X-ray diffraction, it was identified that the Na3V(PO3)3N contains 3-dimensional channels, which enables the facile Na diffusion in the structure. The Na (de)intercalation of Na3V(PO3)3N was occur at ~4 V (vs. Na/Na+) via the V3+/V4+ redox reaction and its capacity retention over 3000 cycles was ~67% of the initial capacity.enAttribution-NonCommercial-ShareAlike 3.0 United StatesCathode MaterialsAbstract
