Coating the Future: Laser Tech Redefining Zero Carbon Battery Production

Hymson, a laser & automation comprehensive solution supplier, delivered a speech at The Battery Show Europe 2024 (Hymson booth 8-D70 & 80) on June 18 and 19, titled Coating the Future: Laser Tech Redefining Zero Carbon Battery Production. Share with the industry a variety of new technology applications that reduce energy consumption and improve efficiency in the coating process.

To address the pain points of high energy consumption and low energy utilization in the existing coating process, Hymson launches the 1600 mm double-layer high-speed coating machine for battery factories in Europe. Dedicated to achieving low-carbon and environmentally friendly production methods, Hymson’s coating machines, as key equipment on battery production lines, enabling European customers to enhance their global competitiveness by reducing costs and improving coating quality.

Core benefits of Hymson coating machine: with a low-energy design and innovative technologies, Hymson coating machines aim to enhance coating efficiency, enable intelligent manufacturing, and reduce materials and costs for low-carbon, sustainable production.

Technological roadmap of Hymson coating machine:

• Wide-width and high-speed
  

• Automatic design to enhance equipment OEE
  

• Automatic closed-loop coating adjustment to improve coating quality
  

• Drying energy reduction technology to reduce energy consumption
  

• Online control of drying parameters, standardization of drying process

Most of the energy consumption of a coating machine is generated in the drying process of the electrode. Therefore, effectively controlling energy consumption in this part is crucial for overall battery production energy management. The anode adopts infrared + heating technology, combining hot air and infrared. This involves large-volume circulating hot air and infrared radiation to vaporize liquids, reducing drying energy consumption by 20-60% and saving operating energy. To address the issue of high heat dissipation temperature on the oven's exterior and the resulting significant heat loss, we have upgraded the coating drying oven with an insulation layer and thermal break design. This enhancement increases the oven's insulation, ensuring that the exterior temperature of the oven is less than the ambient temperature +15°C, thereby improving energy efficiency.

Oven parameters can be monitored online. Air valve opening, NMP concentration, oven air pressure, fresh air temperature and humidity, electrode surface temperature, and electrode vibration can be viewed in real time. This ensures that the oven's airflow and temperature fields meet process conditions, thereby enhancing the stability and reliability of the oven drying process and enabling customers to achieve higher productivity.
