Abstract: A method for preparing a sodium super ionic conductor solid electrolyte by low-dimensional crystallization belongs to a field of energy materials. The method is based on the theory of negative ion coordination polyhedron growth unit, and uses low-temperature plasma as a protective gas of a spray drying equipment. While evaporating the solvent in a sodium super ionic conductor solid electrolyte precursor slurry, plasma active groups modify the particle surface of the sodium super ionic conductor solid electrolyte precursor particles in-situ. A free space dimension of crystal growth in the crystallization process is reduced, and directional growth of crystals in the solid phase sintering process is induced. Secondly, the dispersion stability of the sodium super ionic conductor solid electrolyte precursor particles is improved.
