Description

Technical Field

[0001] The utility model relates to the technical field of hard carbon production, in particular to a sintering device for hard carbon negative electrode materials. Background Art

[0002] Hard carbon refers to carbon that is difficult to graphitize and is the thermal decomposition of high molecular polymers. Common hard carbons include resin carbon, organic polymer pyrolytic carbon and carbon black. Carbon refers to carbon that is difficult to graphitize and is the thermal decomposition of high molecular polymers. The modification research of hard carbon materials is one of the important ways to improve hard carbon as a negative electrode material for lithium-ion batteries. Generally, when operators sinter hard carbon negative electrode materials (graphite negative electrode materials), they set different sintering times and temperatures according to the sintering amount. When traditional sintering devices take out the hard carbon negative electrode materials that have been sintered, the temperature of the hard carbon negative electrode materials that have just been sintered is extremely high. If the staff does not have enough strength to hold the clamping tools when taking out the materials, the taken out materials are likely to fall, which poses a certain threat to the safety of the operator. In addition, the sintering box itself does not have a cooling component, which affects the later processing of the material, thereby reducing the use effect. Utility Model Content
