RESIN COMPOSITION AND ORGANIC-ELECTROLYTE BATTERY

WIPO Patent Application WO/2010/147070

A1

Provided is a resin composition having excellent adhesion to metals and high resistance to organic solvents. In particular, the resin composition is suitable for use as a sealing material for organic-electrolyte batteries which has excellent adhesion to terminals or current collectors constituted of a highly heat-resistant metal such as stainless steel or nickel, is less apt to deteriorate even upon contact with high-temperature organic electrolytes, and is less apt to affect the electrolytes. Also provided is a highly reliable organic-electrolyte battery in which the electrolyte is prevented from oozing out from the electrolyte layer by the action of the resin composition. The resin composition is characterized by comprising an epoxy resin (A) comprising an epoxy resin (E1) having an aromatic ring and an alicyclic skeleton and a latent hardener (B). The organic-electrolyte battery has a positive electrode comprising a current collector (13) and a positive active-material layer (2) electrically bonded to the surface thereof, a negative electrode comprising a current collector (13) and a negative active-material layer (6) electrically bonded to the surface thereof, and an electrolyte layer (7) disposed between the positive electrode and the negative electrode, the battery including a sealing part formed by tightly filling the gap between the peripheral edge parts of the two opposed current collectors (13) with a cured object (12) formed from the resin composition.
