The high-temperature carbonization rotary furnace is used for the high-temperature carbonization process of natural graphite. Inside the furnace, graphite is coated with a layer of asphalt or resin-based polymer material at temperatures below 1200 °C. This coating helps prevent the co-embedding of small organic molecules, thereby further improving the rate performance and cycling stability of the anode material. Equipment Dimensions: 47.9×3.8×5.7m
