Method of manufacturing short-preventive all-solid-state battery
A method of manufacturing a short-preventive all-solid-state battery in which a thermosetting insulating resin applied in advance to a pouch-type electrode case provided with an electrode assembly received therein is forced to fill a space between the edges of the electrode assembly during packaging of the electrode assembly to fill vacant spaces between electrodes at the edges of the electrode assembly and may thus prevent physical contact and collision between the electrodes and fundamentally prevent generation of a short circuit caused thereby.
1. A method of manufacturing a short-preventive all-solid-state battery, comprising:
applying an insulating resin to an inner surface of at least one of a pair of exterior members; and
disposing an electrode assembly between the pair of exterior members and bonding edges of the exterior members so as to seal the electrode assembly, said disposing includes:
primarily sealing the electrode assembly by hermetically bonding a primary sealing area of the edges of the pair of exterior members so as to form an electrode case which receives the electrode assembly; and
secondarily sealing the electrode assembly by pressing areas adjacent to the primary sealing area of the exterior members bonded in the primarily sealing,
wherein, in the secondary sealing, the insulating resin, applied to the area adjacent to the primary sealing area of the at least one of the pair of exterior members, fills a space between edges of the electrode assembly and spaces between electrodes at the edges of the electrode assembly.
2. The method of claim 1 , wherein the insulating resin is applied to the entirety of the inner surface of the at least one exterior member or applied to the edge of the inner surface of the at least one exterior member.
3. The method of claim 1 , wherein the insulating resin is applied only to a designated area of the inner surface of the at least one exterior member, and the designated area includes a secondary sealing area of the at least one exterior member corresponding to an area between the primarily sealing area of the at least one exterior member and the edges of the electrode assembly.
4. The method of claim 1 , further comprising pressing the electrode assembly by applying pressure thereto in an electrode stacking direction, after the disposing the electrode assembly between the pair of exterior members and bonding the edges of the exterior members.
5. The method of claim 1 , wherein the insulating resin includes a thermosetting polymer.
