Products Description

Graphite saggers are the product of the rapid development of lithium battery. Due to their high density, long life and excellent safety, they have become the most widely used energy storage system in portable electronic devices and electric vehicles. Electrodes in lithium battery are typically made from graphite and lithium cobalt oxide or other lithium transition metal oxides. Graphite saggers are primarily used to manufacture these electrodes and prevent reactants from mixing, ensuring efficient and safe lithium battery production.
In the following content, we will explain the application of the following graphite saggers in the lithium battery industry.
As a container for holding electrode materials, the lithium battery graphite sagger plays a role in preventing contamination between different electrode materials. It has high strength and thermal shock resistance and is very suitable for high-temperature sintering processes of electrode materials. The structure of the sagger and the material properties of graphite limit the oxidation of lithium battery electrodes during the sintering process, helping to maintain the chemical stability of the electrodes.
Lithium battery graphite saggers have a high thermal conductivity of 150-180 W/mK, which means they can effectively transfer heat during the sintering process, making it even and efficient. This ensures that the reaction proceeds evenly throughout the electrode material, promoting uniform and rapid heating.
The sintering process in lithium battery production is a key step in the lithium battery manufacturing process. During the sintering process, usually at temperatures of about 800-1300°C, lithium electrode materials densify and react with each other to form stable electrodes. Graphite saggers provide uniform heating, insulation and chemical inertness, helping to prevent battery electrodes from deforming at high temperatures.
