High-Temperature Graphitization Furnace for Lithium Battery Anod

Core Value: Specifically designed for high-temperature purification of lithium battery anode materials (artificial/natural graphite). By modifying the turbostratic structure of the material, it significantly improves the specific capacity and stability of the battery. Mass Production Advantage: Adopts a “one-to-many” production mode (one power supply controlling 3–6 furnace bodies), achieving seamless integration between heating and natural cooling cycles, greatly enhancing equipment turnover rate. Technical Assurance: Equipped with an automatic gas inlet/outlet balancing system and a PID-controlled vacuum device with slow opening/closing functions, effectively addressing process challenges such as the light specific gravity, tendency to spatter, and volume expansion of carbon powder. Contact Hotline: 15115399105.

Product details

Overview

As the endurance requirements for terminal digital devices and new energy vehicles continue to rise, improving the performance of lithium battery anode materials has become crucial. High-temperature graphitization is the core method for modifying the turbostratic structure of artificial and natural graphite, thereby increasing battery specific capacity. The anode material-specific graphitization equipment developed by Yuanhang Industrial Furnace has been deeply customized to address the physical characteristics of carbon powder materials, such as high heat capacity and low specific gravity, making it an ideal mass production solution for current anode manufacturers.
