Packaging method for electric power storage units of an ultracapacitor energy storage device

A packaging method for electric power storage units of an ultracapacitor energy storage device, which comprises the steps of:

• providing a first electrode and coating a first annular glue wall along the border on a top surface of the first electrode, providing a second electrode and coating a second annular glue wall along the border on a bottom surface of the first electrode with the second annular glue wall corresponding to the first annular glue wall;
• filling an electrolyte solution on the top surface of the first electrode enclosed by the annular glue wall;
• providing a separating plate between said first electrode and said second electrode;
• stacking the second electrode on the first electrode;
• and
• heating and reflowing the first annular glue wall and the second annular glue wall to bind the first electrode, the second electrode, the first annular glue wall, and the second annular glue wall together and to enclose the electrolyte solution and the separating plate between the first electrode and the second electrode with the separating plate not being in contact with the said first and second glue walls.
