How to solve the problems of "low graphitization degree and large batch fluctuations" of lithium battery anode materials?

The high-temperature graphitization furnace is a core equipment developed by Hunan Jingtan Automation Equipment Co., Ltd. for the high-temperature treatment of high-end carbon materials such as lithium battery anode materials, carbon fibers, and graphene. In the production of lithium battery anode materials, the degree of graphitization directly determines the capacity and cycle life of the battery, and the improvement of the degree of graphitization must rely on a sufficiently high heat treatment temperature and a pure atmosphere environment. The high-temperature graphitization furnace for refined carbon adopts advanced heating technology, with a temperature that can reach approximately 2600℃, fully meeting the sintering and graphitization requirements of various materials. Under ultra-high temperature vacuum or inert gas protection conditions, carbon atoms gain sufficient energy to rearrange from disordered layers into ordered graphite crystals. At the same time, impurities in the raw materials are fully volatilized and discharged, achieving the dual goals of purification and graphitization.

The intelligent temperature control system of the high-temperature graphitization furnace is the core guarantee for achieving high-quality processing. The equipment adopts a digital intelligent temperature control system, which automatically and precisely completes the temperature measurement and control process. The system can heat up according to the given temperature rise curve and can store 20 different process heating curves totaling 400 segments. The operator only needs to invoke the process formula of the corresponding product, and the equipment can automatically execute the entire process of heating, holding and cooling without the need for manual supervision, significantly reducing the impact of human operational errors on product quality. The temperature uniformity in the furnace working area has been optimized through design to ensure that products at different positions within the same furnace pass achieve consistent graphitization effects.

The application scope of high-temperature graphitization furnaces covers a wide range of fields from carbon materials to ceramic materials. The equipment can be used for the sintering of battery anode materials, carbon material structural components, C/C composite material products, carbon fibers, carbon materials, carbon fiber ropes, and the high-temperature graphitization of phosphorus flake graphite and other graphite materials. For the production of thermal conductive graphite film, the equipment can be combined with carbonization furnaces at 1200-1600℃ to form a complete thermal conductive graphite film production line. The equipment required for the preceding and subsequent processes of the equipment is reasonably matched, and various sizes and specifications of thermal conductive graphite films can be produced.

The vacuum and atmosphere system of the high-temperature graphitization furnace is the hardware guarantee for its purification capacity. The equipment can operate under vacuum or inert gas protection, effectively removing the residual active gas in the furnace and preventing carbon materials from oxidizing at high temperatures. The comprehensive PLC water, electricity and gas automatic control and protection system monitors the equipment's operating status in real time. When an abnormality occurs, it automatically alarms and executes protection programs, ensuring the safe and reliable operation of the equipment under ultra-high temperature conditions. The equipment adopts an internal circulation pure water cooling system and is equipped with a digital flow monitoring system. With its comprehensive technical advantages of "ultra-high temperature of 2600℃, intelligent temperature control and wide application", the high-temperature graphitization furnace of Jingcarbon has become an important piece of equipment in the new energy materials and special carbon materials industries.
