PURPOSE:To suppress increase in internal resistance during storage by contacting a positive mix with a metal container which also serves as a positive terminal through conductive ceramic powder. CONSTITUTION:In an organic solvent battery, a positive mix is in contact with a metal container which also serves as a positive terminal through conductive ceramic powder. Powder of nitride such as TaN, ZrN, TiN, NbN, and VN, or powder of carbide such as TiC, WC, and TaC is used as the conductive ceramic powder. These ceramic powder is easily produced by vapor reaction method, for example. The conductive ceramic powder is dispersed in a mixed solution of water and alcohol such as methnol and ethanol to prepare paste. This paste is uniformly spreaded on the contact surface of the metal container with the positive mix. |
