Problems solved by technology

By compounding a layer of anti-erosion layer material on the inner wall of the box wall, since the material structure of this layer is basically the same as that of the box and is not dense, it can still react with the matrix to cause the peeling of the composite layer when the erosive medium is in the liquid or gas phase. The improvement of the service life of the body is limited, and the preparation process is complicated and the cost is high

Abstract

The invention belongs to the technical field of saggers for synthesizing lithium battery cathode materials, and provides an anti-corrosion coating for an aluminum-magnesium-silicon sagger. The anti-corrosion coating for the aluminum-magnesium-silicon sagger is used for directly modifying the surface layer of the aluminum-magnesium-silicon sagger, so that the aluminum-magnesium-silicon sagger has an excellent anti-erosion tissue structure and chemical composition; the anti-corrosion coating comprises the following solid raw materials: 30-70% of alkaline earth metal salt; 20%-40% of TiO2; 2%-10%of SiO2; 5%-10% of Al2O3; 1%-5% of borax; 0.1%-0.3% of a dispersing agent; and 0.3%-10% of a binding agent. The anti-corrosion coating further comprises water, and the addition amount of the water is10-40% of the total weight of the solid raw materials. According to the coating, the surface of the aluminum-magnesium-silicon sagger is modified, so that the aluminum-magnesium-silicon sagger has excellent lithium corrosion resistant chemical composition and structure, meanwhile, the preparation process is simple, low-cost preparation can be realized, and the practical value is achieved.

Description

technical field [0001] The invention belongs to the technical field of saggers for synthesizing positive electrode materials of lithium batteries, and in particular relates to an anti-corrosion coating for aluminum-magnesium-silicon saggers. Background technique [0002] The sagger is widely used as a synthetic vessel for powder calcination or reaction. Its application scenarios are usually pusher kilns or roller kilns, and it has been used many times until it cracks or is severely eroded. Aluminum-magnesium-silicon saggers usually have good thermal shock resistance and can be used repeatedly without cracking. They are widely used in the field of lithium battery cathode material synthesis, but their disadvantage is poor corrosion resistance. Thereby the service life of sagger has reached the bottleneck. A prominent problem brought about is that the pollution of the synthesized positive electrode material is becoming more and more serious, which greatly restricts the rapid d...
