PROBLEM TO BE SOLVED: To restrain short-circuiting inside of a battery from proceeding even if a separating function of a separator between a positive electrode and a negative electrode is lost by interposing short-circuit preventing means made of a non-electron conductive substance between the positive electrode and the negative electrode. SOLUTION: A positive electrode having a positive electrode active substance 2 formed at one surface of a positive electrode current collector 1 is disposed opposite to a negative electrode having a negative electrode active substance 5 formed at one surface of a negative electrode current collector 4. In a organic battery in which a separator 3 is interposed between the positive electrode and the negative electrode, a coating layer 6 serving as short-circuit preventing means is formed on a separator side of the positive electrode active substance 2. In the organic battery such arranged as described above, even if the separator 3 is melted with, for example, an increasing temperature inside of the battery, the coating layer 6 having non-electron conductivity is hardly melted since a heat resisting temperature of the coating layer 6 is much higher than that of the separator 3. |
