Provided is a resin composition superior in the adhesiveness to a metal and having high organic solvent resistance, particularly, a resin composition preferable as a sealant for an organic electrolyte battery, which shows superior adhesiveness to a terminal or a collector made of a highly heat resistant metal such as stainless steel and nickel, does not easily develop degradation even when contacted with an organic electrolytic solution at a high temperature, and does not easily influence an electrolytic solution, and a highly reliable organic electrolyte battery wherein leaching of an electrolytic solution from an electrolyte layer is prevented by the resin composition. A resin composition containing (A) an epoxy resin containing at least (E1) an epoxy resin having an aromatic ring and an alicyclic skeleton and (B) a latent curing agent.

Resin composition and organic-electrolyte battery

The present invention provides a bipolar battery made by using a polymer gel electrolyte or a liquid electrolyte in an electrolyte layer, which is highly reliable and prevents liquid junction (short circuit) caused by leak out of an electrolyte solution from the electrolyte part. The present invention provides a bipolar battery laminated, in series, with a plurality pieces of bipolar electrodes which is formed with a positive electrode on one surface of a collector, and a negative electrode on the other surface, so as to sandwich an electrolyte layer, characterized by being provided with a separator which retains the electrolyte later, and a seal resin which is formed and arranged at the outer circumference part of a part of the separator where the electrolyte is retained.

Bipolar battery

The disclosure is directed to a bipolar battery that is constructed to improve battery performance by reducing distortions within electrode material of the bipolar battery. The bipolar battery includes multiple battery elements that each includes multiple unit batteries. Each unit battery contains a conductor having a positive electrode layer and a negative electrode layer. A collector is positioned between adjacent positive and negative electrode layers of adjacent unit batteries, and an accumulated thickness absorption member is used to separate collectors of adjacent battery elements. The bipolar battery may be used in a motor vehicle, such as an electric car.

Bipolar battery and vehicle that contains the batteries

A bipolar battery comprises a bipolar electrode having a positive electrode layer on one side of a collecting foil and a negative electrode layer on the other side of the collecting foil, and a polymer electrolyte layer disposed between the bipolar electrodes. In the bipolar battery, an insulation layer is provided on a periphery of at least one side of the collecting foil.
