Patent ID: 8691431

Claim:
A method of producing a sealing structure of a bipolar battery comprising: a step of stacking a first sealing layer consisting of a thermosetting resin that is not cured on a second sealing layer consisting of a thermoplastic resin; a step of preparing a sealing assembly by heating the first sealing layer and the second sealing layer at a temperature lower than a temperature at which the thermosetting resin of the first sealing layer is cured in order to adhere the first sealing layer to the second sealing layer; a step of stacking the first sealing layer of the sealing assembly on a same surface that an electrode is formed at a peripheral part of a resin collector comprising a thermosetting resin that is cured; and a step of preparing a collector assembly, wherein a contact area of the sealing assembly and the resin collector is sealed by heating the sealing assembly and the resin collector at the temperature at which the thermosetting resin of the first sealing layer is cured to adhere the first sealing layer of the sealing assembly to the resin collector.
