PURPOSE:To increase the discharge capacity per volume when used as an electrode material of battery or photocell by forming polyaniline having fibrous structure in which a mean diameter of fiber is 0.8mum or more. CONSTITUTION:Polyaniline has fibrous structure in which fibers are randomly intertwined and a mean diameter of fiber is 0.8mum or more. Since polyaniline having fibrous structure has high bulk density such as 0.3-0.9g/cm<3>, even when it is used without compression as the electrode material of a battery, discharge capacity per volume is increased and a battery which is compact but has large discharge capacity can be obtained. A mean diameter of fiber is 0.8mum or more, preferably 1-5mum, especially 1-2mum, and by using polyaniline having these fibers, the performance of a battery is further increased. Polyaniline having a mean diameter of 1mum or more has a bulk density of 0.35-0.9g/cm<3>, and it is suitable as electrode material for battery. |
