Organic solvent battery

Abstract

Abstract PURPOSE:To reduce contact resistance and restrain the rise of inner resistance even in storage by bringing a positive electrode black mix in contact with a positive electrode collector body via a conductive layer composed of titanium oxynitride powder. CONSTITUTION:A conductive layer 8 composed of titanium oxynitride powder is interposed between a positive electrode black mix 2 and a positive electrode collector body 6. In this case, the titanium oxynitride powder is made suspension with a solvent such as methanol, ethanol, water, etc., to be paste, and to be consistent paste with thickener such as polyacrylic oxide added. Then one drop of the paste is dropped on the body 6 and then dried, the black mix 2 is pressed to a dried place, and at least a half preferably the whole surface of the contact area between the black mix 2 and the body 6 is covered with the layer 8 made of titanium oxynitride. This enables contact resistance between the body 6 and the black mix 2 to be reduced, and the rise of inner resistance of a battery to be restrained even at the time of storage.
