Sintering sagger of lithium battery positive electrode material

The utility model provides a sintering sagger for a lithium battery positive electrode material. The sintering sagger comprises a base with a hollow cavity structure and a stock bin formed by extending upwards from the periphery of the base. The interior of the sagger base is designed to be of a cavity structure, better heat preservation and heat energy buffering effects can be achieved, and excessive sintering of materials at the bottom by a heating rod is avoided; and the powder charging amount can be adjusted according to the height of a heating rod at the upper part of the sintering furnace during charging, so that excessive top sintering caused by too small distance between the material and the heating rod is avoided. According to the saggar, the loading space is increased, the sintering capacity is improved, the number of used saggars is reduced, and the work of carrying and cleaning the saggars is reduced; and the materials are located in the optimal temperature area, the utilization rate of the optima
