Description

Technical Field

[0001] The utility model relates to the technical field of negative electrode material processing, in particular to a negative electrode material continuous carbonization device. Background Art

[0002] Anode materials, commonly used in batteries and capacitors, refer to materials that act as the negative electrode during the battery's charging and discharging processes. The basic working principle of a battery involves a positive electrode, a negative electrode, and an electrolyte. During charging, the anode material accepts electrons and stores electrical energy, while during discharging, it releases these electrons and provides current. Common examples include graphite and silicon. These materials require continuous carbonization during their use.

[0003] In existing technologies, due to temperature non-uniformity during the carbonization process, some areas can reach excessively high temperatures, leading to over-carbonization of the raw materials. This over-carbonization not only causes changes in the physical and chemical properties of the material but also leads to structural defects in the carbonized product, such as incomplete crystallization or the formation of unnecessary byproducts. The raw materials also spend a long time in a high-temperature environment, resulting in non-uniform carbonization on the surface or within the material. This non-uniformity can affect the conductivity, specific surface area, and cycling stability of the negative electrode material, and thus the overall performance and life of the battery.
