The HKANON manufacturing Process Conforms to the Highest Quality Standards. Using global partnerships and best practices, Custom Lipo battery solution design and manufacturing.

  • Mixing: The material that will be coated on to the anode and cathode is mixed.
  • Coating: Large rolls of raw materials are loaded into the coating machine.
  • Calendering: This machine smashes the electrode like a pasta machine. In effect, making the sheets much thinner so that they can be folded more times.
  • Slitting: Cutting the large sheets to proper width.
  • Tab welding: These machines take the rolls of electrodes, attach a terminal or tab, cut them to the proper length.
  • Winding: Once a pile of a given anode type is made, it is brought together with a pile of the cathode of the same size. A semi-permeable membrane is inserted between the layers, and the three strips are then folded together many times.
  • Top/side sealing: The electrodes are then inserted between the protective housing and thermally welded together on three sides. The fourth side is left open for squirting in the electrolyte.
  • Vacuum drying: Drying the battery in a vacuum
  • Injection: In a carefully controlled environment the electrolyte is pumped into the cell. This part of the manufacturing floor is tightly controlled for humidity and temperature. The fume chamber is even more carefully controlled.
  • Formatting: This is the first charging cycle.
  • Pumping: Air quickly degrades and causes problems with the battery chemistry. The heavy compression helps force out any remaining air from the cells.
  • Capacity test: Testing every cell's capacity
