Microwave Roasting Equipment for Battery Anode Materials, Microwave Energy Saving Enhances Quality and Efficiency

I. Application of Microwave High-Temperature Roasting Synthesis in Power Battery Anode Materials

Technical Features and Introduction of Microwave Production of Lithium Battery Materials

1) Microwave high-temperature industrial equipment enables automatic control, continuous production, rapid heating, easy regulation, energy saving, and environmental protection, significantly reducing industrial production costs and saving over 50% more energy compared to electric kilns.

2) Due to its fast heating speed, microwave high-temperature industrial equipment shortens reaction time. Additionally, since microwave heating involves the material itself absorbing microwaves to generate heat, it has a strong catalytic effect, which can also lower reaction temperatures and improve the stability of material performance.

3) For anode materials, microwave high-temperature roasting greatly enhances the material's tap density and purity, thereby significantly increasing the charge-discharge cycles and charging capacity of power batteries, leading to a substantial improvement in material quality.

II. Technical Principles and Features of Microwave Industrial Equipment:

Power battery material microwave roasting equipment heats up by the material itself absorbing microwave thermal energy. Microwaves are extremely high-frequency electromagnetic waves. In a microwave field, polar and non-polar molecules within an object become polarized, turning into dipole molecules. They align according to the direction of the electric field. Since this electric field is alternating, the dipoles rotate and vibrate with the changes in the electric field. For example, at a frequency of 2450 MHz, they rotate and vibrate 2.45 billion times per second, producing an effect similar to friction between molecules, thereby absorbing the energy of the electric field and generating heat. The object itself becomes the heat source. Microwave heating is a non-contact internal heating method, so the material heats up uniformly from within. In contrast, conventional processes use coal, electricity, oil, or gas kilns, which are energy-intensive or produce pollution and exhaust emissions. Their heating methods rely on radiation, convection, and other heat conduction processes from the outside in, resulting in high energy consumption, low energy efficiency, and long heating times.

Microwave heating offers energy savings (high conversion efficiency to thermal energy, saving over 30% compared to traditional heating methods), environmental protection (no external emissions, effectively reducing harmful substance generation), cleanliness (the material itself absorbs microwaves to generate heat, avoiding contact pollution, improving product quality and yield), and high thermal efficiency (fast heating speed, high energy utilization). The microwave industrial equipment manufactured by Zhongsheng operates at temperatures up to 1600°C, with kiln temperature stability of ±5°C. It supports high levels of automation and intelligent operation, improving the production environment.

III. Introduction to the Features of Hunan Zhongsheng's Microwave High-Temperature Equipment:

1) The equipment uses microwave antennas for large-area energy feeding to avoid localized overheating caused by microwave concentration. The microwave heating cavity employs a wave homogenizing device to ensure uniform temperature of the heated materials.

2) The equipment is equipped with a 1.5KW industrial-grade microwave source, with continuously adjustable power (0.1~1.48kW), ensuring the microwave cavity temperature is uniform, adjustable, and controllable to meet different process requirements and enable 24-hour continuous production.

3) Wearable parts (magnetrons) can be replaced online without stopping the machine.

4) The equipment is derived from proprietary intellectual property. The company currently holds over 20 invention patents and more than 40 utility model patents.

5) The company's microwave high-temperature heating kiln technology and equipment have been included in the National Development and Reform Commission's Key Energy-Saving Technology Promotion Catalog.

6) The company's equipment features unique leakage prevention technology. It automatically alarms and shuts down when microwave leakage exceeds standards. Microwave leakage can be controlled to no more than 1mW/cm² (the standard requirement is no more than 5mW/cm²), significantly improving safety.
