Embodiment Construction

[0010] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0011] Such as figure 1 with figure 2 As shown, a honeycomb sintering plate includes a stainless steel base 1 and a crucible plate 2. The crucible plate 2 is fixed on the stainless steel base 1 by screwing in a fixing nail 3, and the top of the crucible plate 2 sinks to form an inverted truncated cone shape In the inner cavity 4 of the crucible plate 2, a honeycomb plate 5 with matching shape is placed in the inner cavity of the crucible plate 2. The honeycomb plate 5 is composed of a plurality of honeycomb holes arranged closely adjacent to each other. A connecting fixing member 6 is insta...

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 lithium battery cathode materials, and particularly relates to a honeycomb sintering disc. Background technique [0002] The sintering process of lithium battery cathode material requires the cathode material to be put into a special container, and then pushed into the sintering furnace for sintering. However, the current container has some problems that can easily affect the sintering quality of the cathode material. On the one hand, the existing The structure of the material container cannot make the positive electrode material and the atmosphere in the sintering furnace sufficiently contact, resulting in low quality or uneven performance of the sintered product; on the other hand, the number of material containers is large, the distribution of materials is uneven, and the production process is troublesome. , And it cannot guarantee the same degree of sintering of the positive electrode material in a batch o...
