A sealing tool for a pouch type secondary battery, which seals a pouch provided with an electrode assembly therein, the sealing tool comprising:

• a holder elevatably disposed on a side of the pouch;
• a sealing block coupled to the holder to contact the pouch by the elevation of the holder, thereby sealing the pouch, the sealing block and the holder spaced apart from each other in a first direction, and
• a space between the sealing block and the holder,
• a first spacing member in the space between the sealing block and holder;
• and
• a second spacing member in the space between the sealing block and holder, the second spacing member spaced apart from the first spacing member in a second direction,
• wherein the first spacing member and second spacing member extend between a top surface of the sealing block and a bottom surface of the holder, and
• wherein the sealing block can expand into the space.

A sealing tool for a pouch type secondary battery, which seals a pouch provided with an electrode assembly therein, the sealing tool comprising:

• a pair of sealing jaws, each sealing jaw comprising:
• a holder elevatably disposed on a side of the pouch;
• and
• a sealing block coupled to the holder to contact the pouch by the elevation of the holder, thereby sealing the pouch, the sealing block and the holder spaced apart from each other in a first direction to define a space therebetween;
• a first spacing member in the space between the sealing block and holder;
• and
• a second spacing member in the space between the sealing block and holder, the second spacing member spaced apart from the first spacing member in a second direction,
• wherein the first spacing member and second spacing member extend between a top surface of the sealing block and a bottom surface of the holder.
