ELECTRODE SHEET DRYING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18461576 titled 'ELECTRODE SHEET DRYING APPARATUS

Simplified Explanation

The electrode sheet drying apparatus described in the patent application includes multiple hot air blowers, each equipped with a nozzle. The nozzle is designed to blow hot air in a band-like manner towards an obliquely upstream direction. The angle between the first guide surface of the nozzle and the undried active material layer is set to ensure that the band of hot air travels along the undried active material layer for a distance that is at least 15 times the gap from the first upstream-side edge to the undried active material layer, even without the use of a spread prevention part.

  • The apparatus includes multiple hot air blowers with nozzles.
  • The nozzle blows hot air in a band-like manner towards an obliquely upstream direction.
  • The angle between the first guide surface of the nozzle and the undried active material layer is set to ensure the hot air travels along the undried active material layer for a significant distance.
  • This effect is achieved even without the need for a spread prevention part.

Potential Applications

This technology can be applied in various industries and processes that involve the drying of electrode sheets or similar materials. Some potential applications include:

  • Lithium-ion battery manufacturing: Drying electrode sheets used in the production of lithium-ion batteries.
  • Fuel cell production: Drying electrode sheets used in the fabrication of fuel cells.
  • Solar panel manufacturing: Drying of electrode sheets used in the production of solar panels.
  • Printed electronics: Drying of conductive ink or paste used in the production of printed electronic devices.

Problems Solved

The electrode sheet drying apparatus addresses several problems associated with conventional drying methods:

  • Uneven drying: Ensures uniform drying of the electrode sheet by blowing hot air in a band-like manner along the undried active material layer.
  • Spread prevention: Eliminates the need for a separate spread prevention part by setting the angle of the nozzle to direct the hot air towards the upstream side.
  • Efficiency: Increases the efficiency of the drying process by maximizing the distance traveled by the hot air along the undried active material layer.

Benefits

The electrode sheet drying apparatus offers several benefits over traditional drying methods:

  • Improved product quality: Ensures uniform drying, resulting in electrode sheets with consistent properties.
  • Cost savings: Eliminates the need for a separate spread prevention part, reducing equipment and maintenance costs.
  • Time savings: Increases the efficiency of the drying process, reducing overall drying time and increasing production throughput.
  • Energy efficiency: By directing the hot air towards the upstream side, the apparatus optimizes the use of hot air, reducing energy consumption.


Original Abstract Submitted

An electrode sheet drying apparatus includes a plurality of hot air blowers each having a nozzle. The nozzle has a first hot air guide having a first guide surface, a second hot air guide having a second guide surface. The nozzle is configured to blow band hot air toward an obliquely upstream side. An angle formed between the first guide surface and an undried active material layer is set to an angle at which the band hot air travels toward an upstream side along the undried active material layer over a distance longer than or equal to 15 times as large as a gap from a first upstream-side edge to the undried active material layer even without a spread prevention part.
