Innovative Electrode Coating System Patent Filed by Hyundai Motor Company

A patent for an innovative electrode coating system has been filed by Hyundai Motor Company, aiming to solve the issue of interrupted coating operations when filters are replaced. According to the patent, the system includes a slurry storage tank, coating slot die, and lines for transporting the slurry, with features that allow for continuous operation without interruption when a filter is replaced. The claims of the patent describe a method of controlling the system using an upstream selection unit, control unit, and downstream selection unit to direct the slurry flow based on filter status.

Key Takeaways:

• The patented electrode coating system is designed to enable continuous operation of the coating operation line without interruption, even when a filter is replaced.
• The system includes a slurry storage tank, coating slot die, and lines for transporting the slurry, with features that allow for selective flow of the slurry through the lines based on filter status.
• The control unit is configured to determine whether a filter has failed based on measured flow rates, pressures, or other parameters.
• The patent claims also describe additional features, including a set of flowmeters, pressure gauges, and gates that can be used to control the flow of the slurry.
• The controller unit adjusts the flow rate of the slurry through the line based on measured flow rates or other parameters.
• The system is designed to coat the supplied slurry on a current collector.
