Abstract

The invention is suitable for the field of sintering of positive electrode materials of lithium batteries and provides a honeycomb sintering disc. The disc comprises a stainless steel base and a crucible disc body, the top of the crucible disc body is sunken to form an inner cavity in an inverted circular truncated cone shape, and a honeycomb disc body is placed in the inner cavity of the crucibledisc body; the shape of the honeycomb disc body is matched with that of the inner cavity of the crucible disc body. Before sintering, the positive electrode materials to be sintered are poured into the honeycomb disc body and then smeared flat, the whole crucible disc body is placed in a sintering furnace for sintering, the honeycomb-shaped structure is stable and easily even when being heated, the contact area of atmosphere and the positive electrode materials is increased, and the efficiency of sintering the electrode materials is improved; a pull rod is fixed to the center of the honeycombdisc body through a connection fixing part, a pull ring is arranged on the pull rod, the honeycomb disc body is conveniently taken out after sintering, the crucible disc body inclines after sintering, and a certain gradient is formed in the side wall of the inner cavity of the crucible disc body so that sintered products can be easily poured out.

Description

technical field [0001] The invention belongs to the field of sintering of positive electrode materials of lithium batteries, and in particular relates to a honeycomb sintering disc. Background technique [0002] The sintering process of the positive electrode material of lithium batteries needs to put the positive electrode material into a special material container, and then push it into the sintering furnace for sintering. However, there are some problems in the current material container that easily affect the sintering quality of the positive electrode material. On the one hand, the existing The structure of the container can not make the positive electrode material in sufficient contact with the atmosphere in the sintering furnace, resulting in low quality or uneven performance of the sintered product; on the other hand, the number of containers is large, the distribution of materials is uneven, and the operation of the production process is troublesome , and it cannot ...
