Abstract

The invention discloses a sodium-sulfur cell solid electrolyte ceramic tube molding die positioning device in the field of energy storage. The sodium-sulfur cell solid electrolyte ceramic tube molding die positioning device comprises an annular positioning support and a positioning ring used for positioning a rubber sleeve and a core bar in a sodium-sulfur cell solid electrolyte ceramic tube molding die; and the positioning ring is horizontally arranged and is fixed to the radial inner side of the bottom of the positioning support through three-point positioning. The sodium-sulfur cell solid electrolyte ceramic tube molding die positioning device has the beneficial effects that the coaxiality of the rubber sleeve and the core bar in the sodium-sulfur cell solid electrolyte ceramic tube molding die is guaranteed, the wall thickness uniformity of a sodium-sulfur cell solid electrolyte ceramic tube can be improved, the size accuracy of the sodium-sulfur cell solid electrolyte ceramic tube is effectively improved, and the homogeneity and the performance stability of sodium-sulfur cells are better facilitated.

Description

technical field [0001] The invention relates to a positioning device for a forming mold of a sodium-sulfur battery solid electrolyte ceramic tube in the field of energy storage. Background technique [0002] A sodium-sulfur battery is a secondary battery that uses a solid electrolyte ceramic tube as the electrolyte and diaphragm, metallic sodium as the negative electrode material, and non-metallic sulfur as the positive electrode material. It has the advantages of large capacity, small size, high efficiency, and long life, and can be used in power grid peak shaving and valley filling, emergency power supply, new energy access, power quality optimization and other fields. [0003] The commercial production of solid electrolyte ceramic tubes generally adopts a dry isostatic pressing method, which includes the steps of feeding, pressing and demolding. Addition step: Na-β″-Al 2 o 3 The powder is added into the cavity of a molding mold corresponding to the shape of the solid e...
